ABSTRACT:
The hydrostatic actuator in a constant displacement type radial piston pump or engine includes two telescopically arranged component parts separating a high pressure side from a low pressure side for a working medium, and defining a variable pressure space therebetween. The pressure space communicates with the high pressure side via a flow restrictor and with the low pressure side via a pressure limiting valve. The telescopically arranged components parts act as piston-like members and adjust the gaps between the outer end faces of the component parts and their control surfaces of the actuator in response to the pressure in the pressure space.
