Hydraulic displacements unit and method of assembly thereof

Abstract From the Canadian patent

Abstract, A hydraulic displacement unit of the axial piston fixed displacement type having a rotatable cylinder block with axially reciprocal pistons each, of which has a slipper associated with a swash surface, as defined by a thrust plate, and structure for obtaining fixed maximum clearance between the slippers and the thrust plate. This fixed maximum clearance is achieved by the use of the controlled positioning of a slipper retainer bearing relative to the surface of the thrust plate by use of a tubular member positioned within the cavity of the unit housing which is securely located and positioned by assembly of an end cap to the housing to be located between the thrust plate and the …
