CRANK-PISTON HYDRAULIC ENGINE Russian patent published in 2024 - IPC F03C1/04 F03C1/22 F03C1/34 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, namely to crank-piston hydraulic engines. Crank-piston hydraulic engine comprises housing 1, radially mounted double-acting hydraulic cylinders 9–14, shaft 2, on which crank 3 is installed, rocker mechanism mounted on crank 3, including guide in form of disc 4 and rod 5, rigidly connected to disc 4 to retain it from rotation relative to crank 3 and moving reciprocating in rotary guide bushing 6, hydraulic control device 15 with shaft 16, pipelines 17, pressure and drain connection ports 18 and 19. Hydraulic cylinders 9–14 are hinged to housing 1 by means of fixed axes 7, and ends of rods of hydraulic cylinders 9–14 of action are hinged on disk 4 by means of movable axes 8 symmetrically around the circumference. Piston and rod cavities of hydraulic cylinders 9–14 are connected by means of pipelines 17 and device 15 with ports 18, 19. Shaft 16 is rigidly connected to shaft 2, on which crank 3 is installed.

EFFECT: invention is aimed at reducing metal consumption, simplifying the design and improving reliability of the crank-piston hydraulic engine.
