FIELD: engines and pumps.SUBSTANCE: pump consists of a cylinder, two suction valves, a stock, a piston, a delivery cavity, a discharge line, two bypass channels with bypass valves, which are located inside the piston. The stock is made in the form of a plate separating the suction cavity into two chambers. Each chamber has its suction valve. One of the bypass channels connects the delivery cavity to one chamber of the suction cavity. The second bypass channel connects the delivery cavity to the other chamber of the suction cavity; with that, bypass channels mutually cross each other.EFFECT: possibility of accurate dosing of pumped liquids and formation of a homogeneous mixture of them.1 dwg |
