ABSTRACT:
Hydrostatic transmission comprises a radial piston pump assembly having an axis of rotation and a gear motor. A hydrostatic fluid pathway extends between the gear motor and the radial piston pump such that the gear motor is fluidly coupled to the radial piston pump, wherein the gear motor comprises at least one gear which is capable of being rotatably driven by a fluid being transported along the fluid pathway. Preferably, a piston guide retains the piston heads against the corresponding slippers without requiring any kind of direct mechanical linkage to maintain such coupling. The present invention further provides a hydraulic shock absorber which absorbs pressure pulses generated by a rotating rotary cylinder block of a radial piston assembly, which may be either a pump or a motor.
