Abstract
There is provided an improved airless paint spray pump having an intake, an inlet valve assembly, a pumping chamber, an outlet, an outlet valve assembly, and stroke pumping means for pumping the fluid paint into the pumping chamber through the intake during the intake stroke and through the outlet on the pumping stroke. The inlet valve assembly includes a flat valve which cooperates with a valve seat at the intake and is displaced from the valve seat during the intake stroke of the pumping means and is seated on the valve seat during the pumping stroke of the pumping means. The flat inlet valve replaces the previous ball type inlet or check valve thereby expanding the design capabilities of the pump.
