Pressure regulator valve with incremental pressure adjustments

Abstract

A pressure regulating valve includes a housing defining a fluid passage between at least one inlet and one outlet. A ball valve is positioned within the fluid passage and biased by a spring. A cam is in biased engagement with the spring and ball valve to regulate pressure of fluid passing through the fluid passage. The cam includes multiple faces, each face milled to a different depth, and means for adjusting a position of the cam relative to the ball valve, such that a different face of the cam enters into biased engagement with the spring of the ball valve, thereby altering a compression force exerted by the spring on the ball valve. The faces of the cam correspond to increments of desired pressure adjustment, such that rotation or movement of the cam surface between different faces results in discrete changes to the pressure of fluid passing through the valve.
