<p>A spray gun (10) includes a body (12) with a barrel portion (14) having an inner chamber that extends therethrough from a front to a rear portion, and a grip portion (16). The grip portion (16) includes a water inlet conduit (12) and water outlet conduit (124) disposed therein that each extends through the grip portion (16) to the internal chamber. A spray nozzle (28) is disposed within the front portion of the barrel (14) and includes a valve (34) disposed around an inlet end of a passageway extending therethrough. A poppet assembly (38) is slidably disposed within the inner chamber and has a cylindrical body with the valve element (42) at one end that is adapted to form a liquid-tight seal with the valve seat (34) when the gun is operated in a no flow position. The poppet assembly also includes a diaphragm (48) at an opposite end of the body (12) that is adapted to form a liquid-tight seal with an adjacent portion of the inner chamber. The water inlet conduit (12) is positioned within the inner chamber adjacent the diaphragm (48) to dispense water adjacent the valve element (42) and the water outlet conduit (124) is positioned adjacent the diaphragm (48) to receive water circulated through the inner chamber. The spray gun (10) includes a spring retaining body (64) attached to the rear portion of the barrel that is adapted from accommodating pivoting attachment of a handle (100) thereto, and for accommodating a spring (114) to maintain engagement between the valve element (42) and the valve seat (34) in a no flow position. The spring retaining body (64) and handle (100) are each configured to provide dual-action pivoting movement of the handle.</p> |
