REVERSIBLE AXIAL-PISTON ROTARY DISPLACEMENT HYDRAULIC MACHINE Russian patent published in 2007 - IPC F04B1/20 

FIELD: mechanical engineering.

SUBSTANCE: proposed hydraulic machine contains cylinder block with working chambers, hydraulic distributor with spherical working chamber, set of piston with connecting rods resting by heads on spherical seats of inclined disk rotating in axial and radial supports of housing. Shaft installed on rotary support is rigidly coupled with cylinder block and inclined support disk. It contains bevel gear train with ratio I=1 with common center of vertices of reference cones on intersection of shaft axis with center of circumference of inclined plane of connecting rod supports. Centers of heads of connecting rods are arranged in rotating plane of inclined disk axially symmetrically relative to common axis of rotation. Axial and radial supports in rotary supports of inclined disk are provided with spaces of balance hydrostatic relief of joints between movable and fixed surfaces of supports. Through channels in pistons-connected rods communicate with corresponding cylinders of block. Ratio of sizes of hydrostatic relief space is chosen to provide balancing of forces pressing support ring to and forcing it off fixed part of support. Value of clearance providing adequate leaks is made self-adjusting owing to throttling of liquid in channels. Supports of connecting rods are arranged in one plane passing through axis of shaft. Hydraulic machine is furnished with coordinator consisting of involute splines on shaft coupling position of cylinder, block, inclined disk, bevel gears ands driving unit-coupling.

EFFECT: reduced weight and load, friction losses in rotary supports, increased efficiency.
