Abstract
The hydrostatic piston machine has a smooth cylindrical pintle which is fixedly mounted in the housing and on which a cylinder block is rotatably mounted. The guide member for the pistons is eccentrically mounted about the pintle and has means thereon for supplying and/or taking off the torque of the machine. The eccentricity of this guide member is adjusted by a movable guide means within the housing. This guide means is controlled by the pressure mdium flowing through the machine.
Claims7
A hydrostatic piston machine comprising
- a housing;
- a pintle fixedly secured within said housing about a longitudinal axis;
- a cylinder block rotatably mounted on said pintle within said housing and about said longitudinal axis;
- a plurality of pistons movably mounted in said cylinder block and peripherally disposed about said cylinder block, each said piston having a support surface at an outer end;
- a guide member mounted about said cylinder block about a second longtudinal axis, said guide member having a plurality of plane guide surfaces disposed tangentially to a circuilar cylindrical surface normally eccentric to said axis of said cylinder block, each said guide surface having a support of a respective one of said pistons guided thereon;
- a movable guide means within said housing mounting said guide member therein for varying the eccentricity of said guide member axis to said pintle axis;
- and
- means on said guide member for supplying and/or taking-off the torque of the machine.
