Described pump housing top is provided with air-vent.
Described piston fixes with piston ring and is connected, and this piston is done by the piston ring and the pump housing and is slidingly connected.
Working principle
Behind the electrical power, the drive piston moves up and down, when piston moves from the top down, gas pressurized in the pump housing, spheroid in the suction tude on the right of making moves right under the effect of spring and blocks suction tude, and the spheroid in the outlet pipe of the left side is moved to the left under the usefulness of spring, leaves relief opening, and gas is discharged from relief opening.When piston moves from bottom to top, produce negative pressure in the pump housing, spheroid in the outlet pipe is moved right under the effect of spring, withstand relief opening, and the spheroid in the suction tude is moved to the left the suction port that leaves suction tude under the effect of spring, gas enters in the pump housing from this suction port, and the motion that goes round and begins again like this reaches the purpose of work.
