<p num="1"><br/> HYDRAULIC PAINT PUMP<br/> ABSTRACT OF THE DISCLOSURE<br/><br/> There is provided an improved airless paint spray<br/>pump having an intake, an inlet valve assembly, a pumping<br/>chamber, an outlet, an outlet valve assembly, and stroke<br/>pumping means for pumping the fluid paint into the pumping<br/>chamber through the intake during the intake stroke and<br/>through the outlet on the pumping stroke. The inlet valve<br/>assembly includes a flat valve which cooperates with a valve<br/>seat at the intake and is displaced from the valve seat<br/>during the intake stroke of the pumping means and is seated<br/>on the valve seat during the pumping stroke of the pumping<br/>means. The flat inlet valve replaces the previous ball type<br/>inlet or check valve thereby expanding the design<br/>capabilities of the pump.<br/><br/> |
