Abstract
The guide means for reciprocating the pistons of the cylinder block are mounted on rings which have bearing surfaces eccentric to the surface on which the cylinder block rotates. These rings are also of a diameter greater than the diameter of the surface on which the cylinder block rotates by at least twice the eccentricity of the machine.
Claims7
A hydrostatic piston machine comprising
- a control journal having a cylindrical surface thereon of predetermined diameter;
- a cylinder block mounted in rotatable relation on said surface of said control journal;
- a plurality of pistons slidably mounted in said cylinder block radially thereof;
- a pair of trunnions on said control journal, each said trunnion having an outer cylindrical bearing surface thereon of a diameter greater than said predetermined diameter and equal to each other;
- and
- guide means for reciprocating said pistons in said cylinder block, said guide means being rotatably mounted on said bearing surfaces of said trunnions in rotatable relation to said control journal eccentrically of said cylinder block.
