Abstract: A variable pressure spray gun with an unloader valve built into the gun so that when the spray pressure is turned off fluid circulated to the gun is returned to the fluid system. Movable valves in the gun selectively direct all of the fluid developed in the pressure system through the outlet of the gun or through a bypass return line to the system and are arranged to selectively vary the pressure of the fluid delivered by diverting selected amounts of the pressurized fluid to the return line. The gun is arranged with counterbalancing fluid forces aiding a gun closing spring and with stop means for selectively limiting pressures delivered by the gun.
