Abstract
A paint spray gun having a dual operating mode trigger. The trigger pivots on a gun body about an axis. The two operating modes are selected by radially positioning the trigger relative to the axis. In a first operating mode, fluid flow to a nozzle is gradually increased as the trigger is gradually squeezed to permit fluid flow control for feathering the applied coating. In this mode, the trigger is mechanically linked for actuating a valve needle. In a second operating mode, a small actuating movement of the trigger operates a valve which causes a piston to move the valve needle to its fully open position. The second operating mode provides only on-off fluid control with a very short trigger stoke and a low trigger force.
