Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
It please refers to Fig.1 to Fig.3, a kind of double plunger high pressure washer pump, including the pump housing 1, motor 2, motor is equipped in the pump housing 1
2 are equipped with cam assembly 3, and 3 upper and lower ends of cam assembly are symmetrically arranged with plunger 4, are connected between plunger 4 and the pump housing 1
Elastic component 5 for resetting plunger 4, the left and right sides of plunger 4 are respectively arranged with out water one-way valve 6 and water feeding one-way valve 7, electricity
Machine 2 drives the rotation of cam assembly 3 successively two plungers 4 to be pushed to move out, and plunger 4 makes one-way water inlet valve 7 by outside ejection
It closes, one-way water outlet valve 6 is opened, and plunger 4, which returns to initial position by the promotion of elastic component 5, opens one-way water inlet valve 7, unidirectional to be discharged
Valve 6 is closed.
