Dual Control Metering Valve

Described is a precision measuring vernier adjustment capability incorporated into a valve combined with volume adjustments, by utilizing a double-coaxial valve stem containing a tapered notch.

The valve shown in Fig. 1 comprises an outer body 10 provided with internal threads, and input and output orifices 11 and 12 for passing fluid into and out of the valve. Disposed within the body 10 is a first coaxial core 13, threaded to be positionable within the body 10 and seat its stem 13a against the input orifice 11 to seal orifice 11. This core 13 is provided with input and output orifices 14 and 15 and a threaded internal coaxial valve element 16 having a conical stem 16a, which can seat against orifice 14 provided in the lower end of the first coaxial body 13 to seal off the orifice 14.

By providing the stem 13a of core 13 with a tapered notch 20, as shown in Fig. 2, fluid flow through the valve 10 can be precisely metered by carefully positioning the stem 13a with respect to the seat provided in the input orifice 11.
