Abstract
The machine has a cylindrical pin mounted at each end in a guide device which is movable so as to change the eccentricity of the guide member axis relative to the pin axis. The guide member is connected over a toothing to a shaft for receiving or taking off power. The toothing can be formed on the outer periphery of the guide member or on a gearwheel secured to a side of the guide member. The guide device may either be of a pivotal type or a slidable type.
Claims5
A hydrostatic piston machine comprising
- a casing having a pair of opposed sidewalls, each sidewall having an aperture coaxially aligned with the aperture in the other sidewall;
- a pin passing through said apertures and said casing and having a longitudinal axis;
- a cylinder block within said casing rotatably mounted on said pin about said axis;
- a guide member rotatably mounted about said pin in said casing, said guide member having guide surfaces disposed tangentially with respect to a circular cylinder having a second axis eccentric to said axis of said pin;
- a plurality of pistons movably mounted in said cylinder block radially of said block, each said piston having a foot at an outer end, each said foot having a plane bearing surface disposed in guided relation on a respective guide surface of said guide member;
- and
- a guide means at each end of said pin on the outside of said casing mounting said pin relative to said casing for adjusting the eccentricity of said pin axis to said second axis, said guide means including a pair of pivotally mounted interconnected levers, each lever receiving one respective end of said pin therein.
