ABSTRACT:
A glide shoe of a hydraulic piston machine has a glide face which is in gliding contact with a gliding surface of a piston-reciprocating element. The glide shoe has a bore which communicates with an interior of a housing of the machine and extends toward the glide face so that a working medium which flows through the bore causes build-up of a hydrostatic pressure between the bore and the glide surface of the piston-reciprocating element. The glide face is continuous and is interrupted only by recess means which occupies not more than a relatively small portion of the glide face so that a relatively high hydrodynamic pressure can build up between the remainder portion of the glide face and the glide surface of the piston-reciprocating element during working movement of the glide shoe relative to the piston-reciprocating element.
