Claim Text:
1. An applicator for dispensing a liquid conformal coating material onto a substrate, the applicator comprising: a body assembly including a valve stem mounted in the body assembly for reciprocating movement between an open position and a closed position, the valve stem including a first end and a second end, the first end of the valve stem engaging the valve seat in the closed position to stop flow of the liquid coating material through the outlet, and disengaging from the valve seat in the open position to allow flow of the liquid coating material through the outlet, wherein the valve actuating mechanism is operative to move the valve stem from the open position to the closed position and is further operative to move the valve stem from the closed position to the open position; a valve stroke adjuster with a stop element for adjusting the distance that the valve stem travels between the open and closed positions; and a resilient dampening element located between the stop element and the valve stem, the resilient dampening element providing a biasing force against the valve stem as the valve stem moves from the closed position to the open position, wherein the resilient dampening element contacts the valve stem in the open and closed positions as well as during movement of the valve stem between the open and closed positions.
