FIELD: engines and pumps. ^ SUBSTANCE: invention relates to devices intended for pumping over liquids, in particular, to the design of hydraulic eccentric pumps. The pump consists of casing (1) with inlet (2) and outlet (3) openings, eccentric shaft (4) accommodating oscillating or rotating cylindrical piston (5) and separator (6) separating the low- and high-pressure zones. The cylindrical piston inside space accommodates a counterweight fitted on the eccentric shaft. Separator (6) is a plate with one end attached to axle fitted into casing (1) and the other end being in contact with cylindrical piston (5). ^ EFFECT: higher reliability and efficiency, simpler design. ^ 6 cl, 6 dwg |
