  • Two-stage high-pressure pump with high sealing performance
    Patent number: 11002263
    Abstract: A two-stage high-pressure pump includes a reduction gearbox disposed in front of a motor, a-crank shaft connected to an output shaft of the reduction gearbox, a connecting rod having one side connected to the crank shaft and the other side connected to a primary piston, a primary one-way valve disposed at one end of the primary piston, and a gas storage chamber provided at the middle of the primary piston. The other end of the primary piston is connected to a secondary piston rod in a highly sealed manner. The secondary piston rod is provided with a vent in the middle, and the other end of the secondary piston is connected to a high-pressure piston. A secondary one-way valve is disposed in the secondary high-pressure piston. A noise attenuating filter and a one-way valve block are disposed at an air inlet of the primary cylinder cover.
