PUMP UNIT WITH TWO PUMPS, SYSTEM, APPLICATION, AND METHOD |
摘要 |
FIELD: engines and pumps.SUBSTANCE: device comprises two pumps, each including pumping cylinder, and reciprocating pumping piston. Pumping piston confines pumping chamber in pumping cylinder communicated with fluid pump port. Actuator is connected with pumping piston. Proposed device comprises also the means to define magnitude dependent upon pumping piston position in pumping cylinder. Besides, it comprises first set of valves communicating every port of pump unit with feed line and discharge line. Note here that pump comprises fluid flow controller to adjust fluid flow by magnitude dependent upon pumping piston position in pumping cylinder.EFFECT: controlled fluid pressure, continuous or pulsating flow.22 cl |
