HYDRAULIC PUMP OR MOTOR (VERSIONS) Russian patent published in 2024 - IPC F04B53/16 F16B5/02 

FIELD: engines and pumps.

SUBSTANCE: group of inventions relates to hydraulic pumps or engines. Hydraulic pump (48) or motor with mounting configuration for increasing torque comprises shaft (58) defining longitudinal axis (64), axis Y extending upwards and at right angle from axis (64), and axis X passing at right angle to axis (64) and axis Y, housing (60) having a first longitudinal end, a second longitudinal end and a cavity extending from the first longitudinal end to the second longitudinal end, several mechanical components, including one interacting with hydraulics, which are arranged in cavity, and also cover of manifold attached to the second longitudinal end and forming inlet and outlet holes. Shaft (58) extends from the cavity beyond the first longitudinal end of housing (60). Mounting flange (78) is located at the first end of housing (60). Flange (78) forms a pair of slots for bolts located along axis X on both sides of shaft (58). Each slot of a pair of slots (80) for bolts has center (82) of radius and a guide ridge extending in a longitudinal direction from flange (78) and having diameter (88). Centers (82) are spaced apart by distance X (84). Ratio of dimension X (84) to diameter (88) ranges from 1.1 to 1.5.

EFFECT: group of inventions is aimed at increasing torque.
