The object of the invention is to provide a compressed air or fluid cleaning gun with a simple valve that allows a larger medium flow, a fine progressive control and a cleaning gun that will cope with rough service. The construction of this cleaning gun is a pistol shaped body (1-1), a flexible hose, a trigger assemble (1-2) that has a roller (1-4) fitted to serve as a pinch roller against hose (1-3) to stop medium flow while not in use. To operate, the trigger assembly (1-2) is simply drawn in towards the body (1-1) by finger pressure, which releases the pinch pressure from the flexible hose (1-3) and allows medium flow through the gun. |
