Abstract
Outlet valve assembly for a paint sprayer and the like includes a spring stop engageable by the outlet valve during opening of the outlet valve to dampen the outlet valve movement during opening of the outlet valve. There is a slight initial clearance between the spring stop and outlet valve when the outlet valve is in the closed position. During each cycle of operation of the paint sprayer, the impact of the outlet valve striking the spring stop compresses the spring stop somewhat, whereby the distance between the spring stop and outlet valve when the outlet valve is in the closed position is less than when a rigid stop is used to obtain the desired amount of outlet valve travel during opening of the outlet valve. At the end of the delivery stroke of the pump, the force of the spring stop acting on the outlet valve pushes the outlet valve to the closed position.
