ABSTRACT:
A spray gun having a trigger lever operated supply valve which includes a reciprocating hollow valve sleeve and a free floating spherical valve element to close the hollow in the reciprocating valve sleeve when the valve sleeve is in its closed position. The free floating spherical valve element and the valve sleeve are located in a chamber which has at least two exit ports spaced from one another at a distance in excess of the diameter of the spherical valve element. End areas of the valve sleeve are equal and subject to the pressure of the material flowing through the valve in its open position to provide a balanced force on the valve sleeve when the valve is open and to help a bias spring to hold the valve in the closed position.
