ABSTRACT:
A variable pressure wand or gun for connection to the flexible conduit of a pressure fluid cleaning system such as used in car washes and the like. Parallel high pressure and low pressure barrels are connected by a fluid passage having a normally open pressure fluid discharge valve plunger therein. A selectively hand operable grip and lever are provided for closing or seating the valve plunger against fluid pressure in the system, the degree of closing being proportional to the force applied to the grip. The high pressure barrel is equipped with a spray or jet nozzle and the flow of fluid to the low pressure barrel is controlled by the operation of the valve plunger.
