Abstract
The present invention relates to a pump unit applied to a high-pressure cleaning machine, including: a water inlet chamber, a water outlet chamber, and a central chamber connected to the water inlet chamber and the water outlet chamber. The pump unit further includes a plunger disposed in the central chamber and an eccentric mechanism connected to the plunger. The eccentric mechanism drives the plunger to perform reciprocating motion in the central chamber.
