A housing for a pressure washer for internal components of the washer such as a pump, an electric motor for the pump and a valve assembly. The housing has first and second identical interconnected housing halves. The inner surface of the housing halves include pairs of ribs interacting to engage the internal components.

Pressure washer

A pressure washer according to the preferred teachings of the present invention is disclosed including a pump driven by a gear reduced, high speed, series universal motor supported in a housing by a switch housing. The motor is stopped and started by a pressure actuation switch to remove the necessity of an unloader valve. A valve assembly is provided which includes provisions for allowing or for preventing weepage through the pump and for relieving excessive pressure. The housing is formed of identical, non-mirror image housing halves which are interconnected end for end. Pairs of ribs upstand from the inner surface of the housing halves, with the first of the pair of ribs of the first housing half interacting with the second of the pair of ribs of the second housing half to engage the internal components while the second of the pair of the first housing half and the first of the pair of the second housing half not interfering with the internal components. The switch housing interacts with abutting ribs of the interconnected first and second housing halves to create an air baffle for dividing the housing into hot and cold compartments, with the electrical components of the washer located in the hot compartment and the water components of the washer located in the cold compartment. The switch housing includes a key slot which clamps the pressure line to a nipple on the switch and which holds the switch in the switch housing protected from the elements by the motor supported thereon.
