Abstract
Abstract A metering valve for metering or mixing either liquid or gases of different types is disclosed herein. The valve comprises a body portion having a chamber formed therein. A metering valve is rotatably mounted in the chamber and has a plurality of spaced apart valve elements rotatably mounted therein which have peripheral skirt portions provided thereon with a plurality of spaced apart passageways extending therethrough. A plurality of inlet conduits are in communication with the passageways formed in the valve elements and are in communication with sources of different liquids or gases. A plurality of outlet conduits are in communication with the passageways formed in the valve elements. The arrangement of the valve elements and the passageways formed therein is such that all of the gases or liquids in the inlet conduits may be mixed and so that any of the gases or liquids can be excluded from the final mixture. Any combination of gases or quantities of gases may be achieved through the selective rotation of the valve elements.
