Gas mixt. valve with two inlets and outlets - has central peg of conical form with two gas transfer ports permitting hydraulic resistance variation

Abstract

Abstract The valve for controlling the mixture of two gases consists of a rotatable core (50) and a housing (51) with an opening (52). The control of the flow is by means of two proportionating ports (53, 54) which are arranged to have openings on diametrically opposite sides of the core and connect with axial flow ducts (57, 58) for two inlet gases, typically oxygen and nitrogen. Rotation of the valve stem by a kneeled top (66) enables variable areas of flow duct to be exposed to the outlet ports and produces two types of mixture (A, B) in different proportions. The core member is of conical form.
