A fluid system for supplying a high pressure stream of fluid is disclosed in which a novel, hand-held nozzle and valve assembly is provided for controlling the flow of fluid from a high pressure pump to a nozzle. The assembly includes a valve housing having a pressure relief or dump outlet and a valve member which is movable between a position in which fluid is dumped or relieved through the pressure relief outlet to a position where substantially all of the fluid flow is through the nozzle. A flat, fluted valve member is utilized to minimize wear, and misalignment and to conserve space. Means, such as a muffler, is provided for diverting the fluid flowing through the pressure relief outlet in such a manner to substantially reduce kick of the assembly when the pressure in the valve housing is relieved. The assembly is also arranged to permit use of different types of operating handles with the same valve housing.
