METHOD OF GRAVITATIONAL CLEANING OF WORKING SURFACES AND HYDRAULIC TANK Russian patent published in 1995 - IPC

FIELD: pump engineering. SUBSTANCE: exhaust working fluid enters above-slot space through drain pipe line and pipe line and is decelerated in the slot between disk , plate provided with a flange projected out of diametrical surface of the disk, and wall of a ring shield. The working fluid, which has been free from the air bubbles, enters the space with a low speed and gets free of heavy fractions. Next, the working fluid flows to the sucking section through slots defined by baffles and then enters the sucking pipe line through sucking unit provided with float, disk, and plate.
