Abstract
A spray gun of synthetic resin composition having a hollow barrel with a pistol grip handle including an actuating trigger pivoted from the butt end of the handle, the trigger being mounted to open and close a valve which, in closed position, seals against a valve seat in a passage between the inlet and the outlet of the spray gun. A spring is provided to urge the trigger and valve toward closed position while a latch is positioned on the free end of the trigger to lock the valve member in open position. Hydraulic balance of the valve member is achieved by proper dimensioning and arrangement of the fluid passage, valve member, valve stem and other related parts.
