Abstract

An airless paint sprayer (10) includes an inlet check valve assembly (62) having a dual spring configuration which allows for increased travel distance of the inlet check valve (62) thereby increasing the fluid flow through the valve without diminishing response time of the valve or the priming operations of the system. A dampener also contributes to lessening the cavitation and loss of pressure in the paint sprayer (10) and comprises a generally T-shaped fitting (36) in which one leg (46) of the T-shaped fitting (36) is capped and includes a trapped volume of air (52) to dampen acceleration/deceleration forces and acceleration spikes being transmitted from the pump (20) to the fluid being pumped through the fitting (36).
