Abstract:
A gun for producing a flow of high pressure fluid, the gun having a gun body with a grip and a barrel, said grip having a first passage extending through it for directing compressed air into the barrel, a control button for allowing the air to pass through said first passage in said grip, a second passage extending completely through the barrel from one end of the barrel to the other end of the barrel, a nozzle coupling at the one end of the barrel and a valve at the other end of the barrel to which a hose for delivering fluid to the gun may be attached, an inlet into the gun body for compressed air or fluid, a sleeve in the barrel between the ends of the barrel in which the fluid introduced through the other end and the compressed air are mixed and through which the mixed fluids may pass to cause the mixed fluids to be ejected out through the nozzle and the valve being operable between two positions for allowing fluid from the hose into the passage and for preventing fluid from the hose from flowing into the passage, said sleeve having circumferentially spaced passages extending through it with said first and said second passages extending along, and at an inclined angle, relative to the longitudinal axis extending along the barrel.
