AXIAL PLUNGER HYDRAULIC MOTOR Russian patent published in 2012 - IPC F04B1/20 

FIELD: mechanical engineering.

SUBSTANCE: hydraulic motor comprises a body, and an cylinder unit in-built by bearing assemblies and coupled with an output shaft of a hydraulic machine. The latter with one end portion is movably coupled with a rigid end distributor. In its other end portion, plungers are introduced in the cylinders of the cylinder unit. On each plunger, a bearing shoe resting against a sliding surface of a swash plate pad is mounted from its other end through a spherical joint. The swash plate pad is rotatable about the plate in a plane perpendicular to an axis of this plate and coupled by a mechanism with an engine integrated in the hydraulic motor.

EFFECT: decreased power consumption.
