Abstract
A spray gun for use with a source of pressurized liquid provided through a supply hose is disclosed having a body with hose connection means at the rear portion thereof and a pistol grip-style handle extending therefrom. The body has a longitudinally passageway extending from the hose connection means to the longitudinally opposed fluid dispensing end of the body. Disposed within the passageway is a plunger, slidably movable between opened and closed positions to selectively allow the dispensing of fluid through the exiting end of the body. The plunger includes a longitudinally bore partially therethrough, the rear portion of the bore being in fluid communication with the hose connections means, and radial bores providing fluid communication between the front end of the longitudinal bore and the internal passageway of the body. The trigger disposed in the handle is operatively connected to a leaver which, upon depression of the trigger, engages a pusher ring which drives the hose connection means and the plunger rearward, thereby moving the plunger from its closed to its open position. A return spring disposed in the passageway provides resistance and biases the plunger in its closed position. The trigger includes automatic locking means which must be disengaged prior to depression of the trigger.
