Abstract: The vehicle has a body provided with ground-engaging portions and has an imaginary longitudinal medial vertical face of symmetry. At least one pair of devices which produce fluid streams is disposed substantially symmetrically on opposite sides of the face of symmetry. The devices have axes of rotation which parallel one another and the said face of symmetry. The body has further mounted thereon at least one pair of matching hydraulic motors whose rotors are connected with the fluid-stream producing devices to drive the same. The motors are supplied at the same rate of flow with streams of hydraulic pressure fluid, and consequently the fluid-stream producing devices are driven at equal velocities and, in turn, produce equal reaction thrusts symmetrically on both sides of the said face of symmetry. This stabilizes the attitude of the vehicle and produces forward movement in the direction of its longitudinal axis.The arrangement of the invention provides a controlled movement of the vehicle independent of the ground whereon the vehicle travels. Thereby it can travel on slippery ground. In addition the thrust-force of the vehicle is increased by means of utilizing a plurality of fluid stream producing devices. Such application of a plurality of fluid stream producing devices gives better efficiencies and considerable bigger thrust, than a single fluid-stream producing device would do at the same power installation. Thrust, control of movement and adaptability for travel on different grounds are increased.

Abstract: Piston shoes in radial piston devices of the prior art were provided with balancing fluid pressure pockets of circular configuration or of elongation normal to the movement direction of the piston shoes. Piston shoes had to provide the space for said pockets and thereby extended over the diameter of the piston. That resulted in deformation of the piston shoe and in friction in areas that cannot be lubricated between the piston shoe outer face and the piston actuator guide face. The invention provides a pair of balancing pockets normal to that of the prior art and extended in the movement direction of the piston shoes. Piston shoes are therefore short in the direction of the pivot axis, deformations are prevented and the areas that cannot be lubricated are reduced to a minimum or removed. The piston shoe becomes thereby able to operate under higher pressures, increased relative speeds and with better efficiency at assured perfect lubrication between neighboring faces.

Abstract translation: 现有技术的径向活塞装置中的活塞鞋具有与活塞鞋的移动方向垂直的圆形构造或伸长的平衡流体压力袋。 活塞鞋必须为所述袋提供空间，从而在活塞的直径上延伸。 这导致活塞靴的变形和在活塞靴外表面和活塞致动器导向面之间不能润滑的区域中的摩擦。 本发明提供了一种与现有技术相一致的平衡凹槽，并且在活塞鞋的移动方向上延伸。 因此，活塞鞋在枢轴方向上较短，防止变形，并且不能润滑的区域减少到最小或去除。 因此，活塞鞋能够在更高的压力下增加相对速度，并且在相邻的面之间确保完美润滑的情况下能够以更好的效率操作。

Abstract: A radial-piston machine has a rotor formed with a plurality of each a piston carrying radial cylinders. Each such piston is formed on its radially outer end with a part-spherical seat and a part-spherical portion of a respective piston shoe that rides on an eccentric cam in the housing is engageable in each seat. Each such piston shoe can move radially into and out of engagement with the respective piston. A pair of end members axially flank the piston shoes with play so that these shoes may also move axially relative to the motor. The piston-engaging portions of the shoes are always engaged radially in said cylinders. The cylinders may have outer portions with a cross-slot extending parallel to the axis of the rotor through said cylinders. The pistons and shoes may embrace each other partially or be radially free of each other, so, that either the connected piston and piston shoe assembly moves radially between end elements associated to the rotor or the pistons and shoes move unconnected to each other radially between said end elements. The piston shoes may have one- two- or three-dimensional free play.

Abstract: In an internal gear pump or motor the insert control member between the inner and the outer gear is provided with balancing pockets, which receive fluid under pressure to counter-balance the pressure forces exerted onto the inner and outer gear of the device. Thereby it is obtained, that the radial forces of fluid onto the inner and outer gear are balancing each other by diametrically located oppositional directed fields of force of pressure in fluid. The inner and outer rotors such float freely between radial forces of fluid. Radial rest loads are prevented and the life of the rotors is extended. There may be a single insert or a plurality of inserts and there may be one or a plurality of suction chambers in the device. Additional outer guide means or pressure fields of fluid under pressure may be provided. The loading of the balancing pockets with pressure fluid may be done through respective passages from areas under pressure to said balancing pockets.

Abstract: A double piston engine has a medial shaft between two pistons which reciprocate in opposed cylinders. From the pistons extend outer piston shafts which serve as control shafts. The outer ends of the cylinders are provided with inlet ports and control recesses while the control shafts have also control recesses and the meeting of the control recesses defines the inlet of the fluid into the cylinders. More details serve to combine a plurality of double piston engines to work in unison in timed relation, to increase the power per a given weight or to use the engine as a hydrofluid conveying combustion engine as well as the prevention of dead spaces by specific valves or configurations and locations. A piston may form a first piston portion and a plurality of secondary piston portions with the sum of the cross-sectional areas of the secondary piston portions equal to the cross-sectional area of the first piston portion.

Abstract: This snap ring has outer and inner fingers which extend slightly from the ring. Thereby it becomes possible to embrace the ends of the fingers by a plier from the outside to press the ends of the fingers towards each other and thereby to widen the inner diameter of the snap ring in a limited extent for moving the ring over a respective bar. The inner face of the ring may be circular or of angular configuration. An accessory shows especially suitable pliers for the use of handling the snap ring.The fingers extend normal to the imaginary medial plane of the ring, the outer face forms partially by a radius around an eccentric axis of the medial plane while the inner face of the ring may form by a radius around a concentric axis of the medial plane and the roots of the fingers should be bigger in radial direction than the length of the eccentricity between the concentric axis of the inner face and the eccentric axis of the outer face to give the snap ring the strength to hold itself against axial deplacement on a metallic bar or pipe.

Abstract: A member oscillates on a face and another member pivots on a bed of the first member. Passages are provided through the members to lead a lubrication fluid under pressure into a fluid pocket between the mentioned face and one of the members. The fluid pressure in the pocket carries a major portion of the load of one of the members on the face. The oscillation of the members has one stroke under higher load and one under less load. The pivotal movement of the other member controls the flow of fluid through the passages to provide high pressure in the fluid pocket at the stroke under higher load and lower pressure in the pocket at the stroke under less load. The arrangement is especially suitable to be provided on pistons and piston shoes of radial piston machines. But it can also serve to carry load on other members of machines or vehicles, wherein at least two movements are taking place and a source of supply of fluid under pressure is available. This present application claims the details of the arrangements of fluid pressure pockets on pistons of radial piston pumps and motors.
