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.
