ABSTRACT:
A dispensing valve mechanism includes means for automatically maintaining a constant flow of fluid through a flow channel under varying fluid source pressure and and utilizes a piston movable within a chamber in response to fluid pressure to regulate the available flow area of a single outlet port in the chamber. The piston is sized to permit fluid flow around the periphery of the piston, and may have an axial flow path therethrough to serve as the primary flow path through the valve mechanism. A spring yieldably opposes axial movement of the piston that would tend to decrease the effective area of the chamber outlet port. An adjustment screw is carried in the valve body for adjusting the force exerted by the spring. The valve is particularly suited for use in liquid dispensing apparatus.
