Abstract:
An air, water, or land vehicle has a body adapted to travel in a normal direction of travel and having a pair of forwardly directed propellers symmetrically spaced to each side of the centerline of the vehicle and each carried on a respective fluid motor. An engine on the vehicle drives at least one pump having two independent working chambers each of whose output is connected to the input of a respective one of the propeller-carrying motors and an adjustment is provided for increasing the discharge rate of the one pump relative to the other and vice versa for steering the vehicle.
Abstract:
A pressure responsive control body in the housing of a fluid handling device has a control face which abuts against the control face at one axial end of a rotor which is provided with working chambers for the inflow and expulsion of a fluid. A portion of the control body extends into a pressure chamber of the housing and the control body is movable axially of the housing. The control body seals a portion of the pressure chamber by means of an eccentrically located cylindrical shoulder a portion of which extends radially beyond the control face. This insures that the position of the pressure center of the eccentric shoulder relative to the axis of the rotor is the same as the position of the pressure center between the control faces. Such positioning of the pressure centers guarantees a smooth running of the control face on the rotor relative to the control face on the control body and prevents relative tilting or adherence of the control faces to each other so that the control mirror between the control faces operates with a high degree of efficiency even at high fluid pressures and at a high RPM of the rotor.
Abstract:
A rotor is rotatably mounted in a housing and formed with angularly spaced radially oriented cylinder bores in each of which a piston is radially reciprocable. The radially outer end of each piston is formed with an inwardly extending recess having a length greater than the length of the piston stroke. A control ring which is eccentric relative to the rotor surrounds the latter, and its inner circumferential surface is slidingly contacted by respective piston shoes each of which is associated with one of the pistons and each of which has a shaft that is freely received in the recess of the associated piston and whose length is also greater than the length of the piston stroke.
Abstract:
A solid fuel preferred to be prepared from cleaned and pressed coal powder to a high density is led into a combustion chamber. Air is compressed to a high temperature which exceeds the self ignition temperature of the mentioned solid fuel. This compressed air is also led into the combustion chamber to meet there the tip of the solid fuel sheet and to ignite and burn the fuel in the hot air in the combustion chamber. The hot burned gas can then be led into an expander and the expander can drive a compressor for the supply of the mentioned hot air. The device then forms a combustion engine with continuous combustion in an external combustion chamber. In my parental U.S. Pat. No. 4,809,503 the solid fule is a fuel bar. This present application deals mainly with a solid fuel sheet or tape which is wider than it is thick. Thereby it is secured that the fuel portions meet exactly the required amounts of hot air locally at a wide meeting and burning place.
Abstract:
When pumping chambers were provided between tapered discs of axial compressibility and expandability, the discs worked perfect in the subcritical pressure range. But in the supercritical pressure range the high pressure in fluid would depart the discs away from each other and open a gap between the discs because the force of pressure in fluid in the chamber between the tapered discs was higher than the internal strength of the material of which the respective coned element was made. The invention now discovers that it is possible to provide a means which prevents the departure of a coned ring from a neighbored ring. The invention obtains this by providing a means which presses under actions of pressure in surrounding fluid the neighboring coned ring elements at all times together for a close and perfect sealing between them. This means which the invention now discloses is the provision of seals radially inwards and outwards of a defined radial dimension of a meeting area between two neighborings discs of a respective pair of coned ring elements. The radial extension of the meeting area defines the force with which the neighboring elements are pressed against each other for a close sealing procedure. The elements are produced from respective material, for example, from hardened stainless steel.
Abstract:
An aircraft has a pair of wing portions with propellers of a propeller pair which are driven and synchronized by a fluid transmission between the power plant and the propellers. A fluid line structure keeps most components of the craft together and consists preferredly of three pipes which are also utilized to carry the driving fluid to and from the motors, to hold the motors and to hold the wings. The take over of a plurality of functions by the interior pipe structure reduces weight and secures safe and economic operation of the craft. The pipe structure can be pivoted in respective bearings to effect the pivotal movement of the propellers and wing portions for either vertical take off and landing or for horizontal flight. The pipe structure is built by pipes without bends in order to make the cleaning of the interiors of the pipes from dirt and from remainders of welding possible. Ribs and holding portions are provided on the structure for assembly and/or disassembly of the wing portions of the pipe structure.

Abstract:
A double piston engine has a doubly acting piston reciprocably provided in a cylinder arrangement to form two working chambers which periodically increase and decrease their volumes. The invention provides inlet means with supply means for a cleaning flow through the working chambers and inlet means and supply means for a loading flow in excess of atmospheric pressure to the respective chambers. Means are further provided to secure that the loading flow enters the respective working chamber after the closing of the inlet for the cleaning flow. By this arrangement of the invention it becomes possible to operate two cycle engines with turbo-chargers or other loaders. A very powerful engine at compact space and low weight is obtained, while the poisenous gases of two stroke engines are prevented to a high degree.
Abstract:
In an axial piston motor or pump the cylinder barrel is mounted on a medial shaft which has a shoulder which axially bears against the front end of the rotor barrel. The rear end of the medial shaft is radially borne in a housing portion. The front portion of the medial shaft is provided with a bearing member of an axial thrust bearing for support on a respective axial thrust bearing member in the housing. On the rear end of the rotary barrel an axially selfthrusting control body is provided to seal the flow of fluid to and from the cylinders of the rotary barrel. The control body presses against the rotary barrel, the rotary barrel presses against the shoulder of the medial shaft and the thrust bearing member of the shaft bears on the thrust bearing member of the housing. As a result thereof the cylinders in the rotary barrel can be straight through bores. The manufacturing of the rotor barrel is thereby simplified and the flow acceleration losses of former bore type cylinders are prevented.
Abstract:
A combustion engine has a combustion chamber separated from the compression and expansion chamber(s). Passages are provided between the combustion chamber and the compression chamber(s) and the combustion chamber and the expansion chamber(s) with respective valves in the passages and inlet and exhaust valves provided in the combustion and expansion chamber. The combustion chamber maintains the combustion after passing fuel into the compressed air received from the compression chamber. The valves and piston heads are formed to prevent dead space in the cylinders in order to obtain a good efficiency by full discharge of the compressed air into the combustion chamber. Fuel cleaning means like, for example, a rotary separator and pure gas collecter are provided in the combustion chamber to separate unclean fuel particles, as, for example, ash or sand in coal, from the burned gases and collect the unclean particles in separated collection spaces. The engine can thereby burn unclean fuels, as for example coal powder or coal sludge and the like. The valves can be timed for different styles of combustion cycles if so desired. The engine may use conventional four stroke or two stroke engine arrangements and provide them with combustion chambers, pistons and cylinder heads of the invention to modify them from gasoline combustion to coal combustion or other cheaper and more avialable fuels for the combustion in the compressed air.
