Abstract (en)
In an axial, variable displacement, positive displacement pump having a swash plate mounted on a drive shaft for rotation therewith and a non-rotatable wobble plate surrounding the swash plate but isolated there from through bearings includes a slide mechanism disposed on the shaft that can be axially displaced along the shaft as the shaft is being driven to thereby vary the angle of inclination of the swash plate and wobble plate relative to the drive shaft. The pump further includes a unitary in-line valve assembly including suction and discharge poppet valves for each cylinder whereby the overall diameter of the cylinder block can be minimized. <IMAGE>
