Abstract
A spray gun includes a body with a barrel portion having an inner chamber that extends therethrough from a front to a rear portion, and a grip portion. The grip portion includes a water inlet conduit and water outlet conduit disposed therein that each extend through the grip portion to the internal chamber. A spray nozzle is disposed within the front portion of the barrel and includes a valve seat disposed around an inlet end of a passageway extending therethrough. A popper assembly is slidably disposed within the inner chamber and has a cylindrical body with a valve element at one end that is adapted to form a liquid-tight seal with the valve seat when the gun is operated in a no flow position. The poppet assembly also includes a diaphragm at an opposite end of the body that is adapted to form a liquid-tight seal with an adjacent portion of the inner chamber. The water inlet conduit is positioned within the inner chamber adjacent the diaphragm to dispense water adjacent the valve element, and the water outlet conduit is positioned adjacent the diaphragm to receive water circulated through the inner chamber. The spray gun includes a spring retaining body attached to the rear portion of the barrel that is adapted for accommodating pivoting attachment of a handle thereto, and for accommodating a spring to maintain engagement between the valve element and the valve seat in a no flow position. The spring retaining body and handle are each configured to provide dual-action pivoting movement of the handle.
