AI Technical Summary

Problems solved by technology

Due to design limitations of typical positive displacement pumps and other types of high pressure pumps, the flow rate through the pump, and thus the flow rate through the entire pressure washer, is limited
Fluid flow through a pressure washer is restricted as it releases high-pressure fluid, making flushing dirt removed from work surfaces a difficult and time-consuming task

Embodiment Construction

[0034] see now figure 1 In the illustrated embodiment, a pressure washer 10 according to the invention is shown. The pressure washer 10 includes a housing 20 that substantially encloses a pump mechanism 60 . The housing 20 has a front end 22 and a rear end 24 that define a longitudinal axis 26 . The housing 20 generally includes a pair of mating housing shells 28a, 28b that cooperate to define a housing cavity (not shown) within which the pump mechanism 60 is mounted. The housing shells 28a, 28b are also cooperatively formed with an inlet aperture 30, an electrical cord aperture 32, and a handle 40 that enables a user to hold the pressure washer 10 in hand.

[0035] The handle 40 has a first end 42 extending from a portion near the rear end 24 of the housing and a second end 44 terminating in the barrel 50 . The handle 40 and barrel 50 are provided with a fluid passage from an outlet 66 of a pump 62 . The fluid pressure at the outlet 54 of the barrel is greater than the fl...
