SELF-SUCTION HYDRAULIC PISTON UNIT FOR WATER TRANSFER Russian patent published in 2018 - IPC E03B5/00 

FIELD: water supply.

SUBSTANCE: invention relates to water supply. Unit consists of a suction line (1), a centrifugal pump (16), a vacuum bottle (2) with a filler neck (5), and a discharge pipeline (18). Unit is additionally equipped with a vacuum bottle (3) with a filler neck (5). In the upper part both vacuum bottles (2 and 3) have float-lever check valves (7 and 8), exhaust valves (6). Vacuum bottles (2 and 3) lower part is connected to the hydraulic distributor (9), which on the edges has power chambers (12 and 13) with membranes (14 and 15) interconnected by a rod (10), on which two pistons (11) are installed. Centrifugal pump (16) suction communication line (17) is also connected to the hydraulic distributor (9). In the pressure line (18), adjustable jets (19 and 20) are installed connected to the float-lever check valves (7 and 8) by flexible hoses (21), and also the check valve (22) and pressure switch (23) are installed. Suction pipe (1) supplies water to the vacuum bottles (2 and 3) through the inlet valves (4).

EFFECT: enabling the uninterrupted water supply to the pressure mainline by the pump, excluding the gases and vapours evolved in the vacuum cylinder effect thereon.
