Abstract: A fluid machine such as a pump, compressor, engine, motor or transmission has working chambers in a rotor and a concentric rotor - hub is provided in the rotor for the reception of a control body therein. The control body has control ports for the control of flow of fluid into and out of the working chambers of the rotor. Pressure fields form in the clearance between the rotor hub and the control body especially around the control ports. Leakage flows from the pressure fields through portions of the clearance between the rotor - hub and the control body which reduces the efficiency of the machine. Therefore, means are provided in the rotor or in the control body to press those portions of the faces of the rotor hub and of the control body, which have those local pressure fields, together, or to narrow the clearance between these faces in the respective areas where those pressure fields are located, in order to reduce the leakage through the clearance between the faces of the rotor hub and the control body.

Abstract: The invention provides an aircraft with propellers with vertical and horizontal axes in combination with pivotable wing portions. At vertical take off and landing the propellers with vertical axes bear the craft while the wing portions are set with their chord parallel to the airstreams through the lifting propellers. When the aircraft flies forward with enough speed, driven by the propeller(s) with the horizontal axis (axes), the lift propellers are set to rest parallel to the forward flight direction of the craft while the wing portions then pivot under the airflow over them into a horizontal position with their chords, at which they are prevented from further pivoting by stoppers in order that the wing portions then carry the craft at the forward flight. The actions of the lift propellers and the wing portions can be effected by power division means between the propellers with vertical and horizontal axes with the result that the wing portions adjust their positions automatically according to the flight behavior of the craft.

Abstract: An air-borne craft is provided with at least two pairs of propellers with substantially vertical axes. One pair of the propellers is provided on the front portion of the craft, the other pair on the rear portion with one propeller of each pair on the left side and the other propeller of the same pair on the right side of the body of the craft. The propellers are provided on their rear directions with flaps which can open and close relative to the profiles of the propellers. The arrangement of at least four propellers secures an economical operation in case of emergency landing and at flight. In case of an engine failure the craft has still a forwardly directed speed. This speed will open the flaps and the flow of air against the flaps will revolve the propellers. Thereby at least one arm of each of the propellers remains acting like a helicopter blade and the four propellers can carry the craft in a gliding procedure, flying forwardly with an angle of descent, towards the ground for the emergency landing.

Abstract: In the European patent application publication EP OS O No. 102 441 a high pressure pump is shown which uses tapered rings (disc spring derivatives) which are clamped together as a pump chamber. The clamping rings required cutting into sections which is expensive and time consuming. The present discoverings now show that the friction at compression of the coned rings was very large. The present invention now discovers that radially flexible ring portions should be provided to the coned ring portions in order to eliminate the friction and to reduce the time and cost of the production of the pump arrangement. The invention further provides U-type pump elements which eliminate the clamping rings. A second pressure led into the space in the housing which surrounds the pump elements makes it possible to increase the pressure in the pump, for example, to double the pressure.

Abstract: An arrangement which includes a coned ring forms with the coned portion an interior space. The interior space decreases and increases its volume, when the coned portion of the ring is compressed and de-compressed. The coned ring has a radial outer portion and a radial inner portion. The radial inner portion forms a bore. The radial outer portion is provided with a seat face portion. The seat face portion contacts and bears a respective portion of a body, which may be a second coned ring, a thrust body or an outer ring. The arrangement is utilized to center a coned ring relative to a neighboring body or to provide and effectively seal a working chamber for the reception and expulsion of a fluid.

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 bearing 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 sack-bare bore type cylinders are prevented.

Abstract: In a vehicle or device a fluid motor is employed to drive rotary members, such as wheels, propellers, tracks. The motor is provided with an arrangement which includes a control means and an axially moveable member. By utilizing the control means, for example, by a flow of fluid, the axially moveable member is used to apply an action, which is not common to the usual operation of fluid motors. The arrangement may be used to arrest the rotor of the motor from rotation when no pressure is in the driving fluid line. It may also be used to control the pitch of propellers with variable pitch arrangements. Also possible is to use the arrangement to automatically obtain an auto - rotation of rotor blades on vertical axes of vertically take off and landing vehicles, when the pressure in the fluid line to the motors for driving the motors drops below a predetermined minimum of pressure. The speciality of the preferred embodiment of the invention is to provide an upper structure of an airborne craft with a plurality of propellers with substantially vertical axes to carry pivotable on the mentioned structure a body of the craft below the mentioned structure, while the body contains the cabine and the power plant as well as the fluid flow supply means, the upper structure is pivotable in a limited extend relative to the body and the fluid under pressure is transferred from the fluid flow supply means in the body to the upper structure and to the fluid motors which drive the propellers of the upper structure.

Abstract: In a pivot bar portion of a piston shoe in a radial piston device wherein the pivot portion is pivotably borne in a bed in the piston which extends normal to the longitudinal axis of the piston, recesses are provided parallel to the pivot axis whereby bearing lands are formed between the recesses. The bearing lands are tracting fluid out of the recesses along themselves and the bearing bed face of the piston, when the shoes pivot in the piston. A perfectly operational forced lubrication between the pivot portion and the piston is thereby assured which results in a long life and very high bearing capacity between the piston and the piston shoe.
