Abstract

An airless paint sprayer (10) includes a dampener to lessen cavitation and loss of pressure in the paint sprayer (10). The dampener comprises a generally T-shaped fitting (36) in which one leg (46) 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).
