Abstract: A control pintle carries a rotor which rotates around the pintle. The rotor has chambers which can take in and expel fluid. Passages of a reduced cross-sectional area carry the fluid to or from the control pintle and to or from the chambers. The control pintle has control parts and fluid lines, as well as certain recesses. Rotor and control pintle are insofar known from the former art. The invention provides unloading recesses in specific relation to the passages and chambers to make the rotor float around the control pintle concentrically or eccentrically in a desired extent. Supply slots are added to assist the build-up of hydrodynamic pressure fields to act in co-operation with the hydrostatic forces. Details are shown, how such supply means become provided or supply be secured.

Abstract: A piston drive for use in diesel engines with a high specific liter output wherein the piston comprises discrete sealing and guiding sections and is constructed, configurated and assembled in such a way that the flow of power from the combustion zone takes place along straight paths directly from the crown to the connecting rod without causing any bending and/or other deformation of component parts of the drive. The piston drive allows for achievement of higher output, without increasing the stroke volume of the cylinder, by using relatively inexpensive piston sections and without reducing the E of the engine.

Abstract: In a fluid pump or motor improvements are provided to the piston shoes therein to permit a higher pressure in the respective device. Other improvements are done to the hydrostatic bearings in radial piston or radial chamber type fluid motors and pumps. A further arrangement is, that plural pistons are applied to permit the use of two different fluids in the respective device. This leads also to the application of disc springs and their modification in a pump or motor to make the pumping of non-viscous fluids like water possible at very high pressure. Motors are provided with arrangements to permit them to drive and to carry simultaneously or to have hollow shafts, whereby improved and novel machines and vehicles are obtained.

Abstract: A piston for an internal combustion engine comprises a piston body of aluminium or aluminium alloy and an insert of a ferrous material having a combustion bowl formed therein. The insert is surrounded by the piston body and the outer surface of the insert and the adjacent surface of the piston body are spaced apart at the crown ends thereof to form an annular gap therebetween which opens onto the crown. This insulates the piston body from the insert.

Abstract: An improved method of manufacturing a swash plate assembly for use in a compressor, fluid motor or similar device in which a plurality of pistons are connected, by means of connecting rods, to a swash plate which drives (or is driven by) the pistons. A plurality of piston assemblies are made by casting the piston around one end of a connecting rod section which is formed with a ball thus providing a ball-socket connection therebetween. Mating spherical ends with through-bores to receive the piston connecting rod section are cast-in-place and captured in sockets within the swash plate. The connecting rod section of the pistons is mated to the through-bores of the mating spherical ends and are positioned in an appropriate fixture to a fixed final relationship. The connecting rod sections are secured to the sidewall of each through-bore by a means such as electron-beam welding to secure the overall length of the final assembly.

Abstract: In a composite, liquid-cooled piston, the upper part consists of ferrous material and is joined by conventional means to the lower part. A ring is provided on the underside of the upper part which bears on the corresponding surface of the lower part and constitutes a radially inner boundary of a cooling passage which is disposed on the upper part and open to the interfacial plane. To improve the cooling action in the hottest regions of the upper part and to achieve a more uniform distribution of temperature in the ring carrying over of the upper part of piston, the upper portion of the wall defining the cooling passage is coated with a material having a high thermal conductivity.
