ABSTRACT:
An airless paint sprayer includes an outlet check valve assembly having a dual spring configuration which allows for increased fluid flow through the valve without diminishing response time of the valve or the priming operations of the system. One of the springs is not engaged when the valve is closed and the other spring has a much lower spring rate and biases the valve toward a closed configuration when the valve is open, closed, and all positions therebetween. The dual spring configuration accommodates highly viscous fluids or paints with maximum fluid flow and no detrimental impact on the priming operations of the sprayer.
