Abstract
The utility model discloses a piston-type double-way pump. The piston-type double-way pump comprises a pump cylinder and a piston, wherein the cylinder cavity is divided into an upper cylinder cavity and a lower cylinder cavity by the piston, wherein the top of the upper cylinder cavity is provided with a first inlet of a working medium, a corresponding one-way valve A , a first outlet and a corresponding one-way valve B. A containing cavity is connected on the lower end of the lower cylinder cavity. A second inlet of the working medium , a corresponding one-way valve A', a second outlet and a corresponding one-way valve B', are mounted at the bottom of the containing cavity a drive shaft is arranged in the middle of the containing cavity, a radial arm is fixedly installed on the drive shaft, the drive shaft drives the piston to move up and down repeatedly through a connecting rod. When the piston goes down, the first inlet absorbs the working medium, the second outlet discharges the working medium. When the piston goes up, the second inlet absorbs the working medium, and the first outlet discharges the working medium. The piston-type double-way pump has the advantages that the working medium can be discharged regardless of whether the piston moves in the positive direction or in the reverse direction in the pump cylinder, the work efficiency is high, and the piston-type double-way pump works regularly regardless of whether the drive device rotates in the positive direction or in the reverse direction.
