POSITIVE- DISPLACEMENT HYDRAULIC MACHINE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: periphery spherical surface of a disk baffle and spherical surfaces of blades are provided with hollows to form chambers for hydrostatic relief and sealing collars. Movable bushing or thrust bearing which forms a space for hydrostatic support, is mounted on face of a driving shaft or in a cover provided form the side of the face of the shaft. The space is in communication with spaces for supplying and discharging passages provided in a case or with working chambers of alternative volume through passages provided in a body of a jaw shank set in axial bore of a driven shaft of in the body of the shaft. Passages are provided with check valves for their opening in the direction of the space of the support. Chambers for hydrostatic relief, which are in communication with oppositely arranged working chambers of alternative volume through passages provided in the blade or in the body of the driven shaft, are provided on the driven shaft on both sides of blade plane of symmetry. EFFECT: improved design
