Airless paint sprayer intake dampener and inlet valve spring

摘要

An airless paint sprayer includes an inlet check valve assembly having a dual spring configuration which allows for increased travel distance of the inlet check valve 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 and comprises a generally T-shaped fitting in which one leg of the T-shaped fitting is capped and includes a trapped volume of air to dampen acceleration/deceleration forces and acceleration spikes being transmitted from the pump to the fluid being pumped through the fitting.
