ABSTRACT:
A high pressure fluid blast gun (10) has a valve assembly (12) and a handle assembly (14) removably connected to each other. Valve assembly (12) has a valve body (16) including a valve chamber (18) having a cartridge therein including a valve sleeve (30), and a slidable valve member (42). A plug (44) retains the cartridge in valve chamber (18). The handle assembly (14) has a mounting plate (70) and a handle grip portion (75) extending therefrom. A guard (76) extends from the handle grip portion (75) to mounting plate (70) for enclosing the trigger (78). A pair of dump passages (62) in valve body (16) communicate with dump port (66) in face (28) of valve body (12). A dump passage (94) in opposed face (71) of handle assembly (14) is in communication with dump port (66) and extends to atmosphere for relief of the high pressure water when trigger (78) is manually released thereby to provide a low pressure flow of water from high pressure supply conduit (24). The embodiment of FIGS. 4 and 5 includes a main gun body (11A) having a cylindrical opening (17A) receiving a cylindrical valve body (16A).
