ABSTRACT:
A flow control valve includes a body having a spherical hollow central section into which a spherical central body fits. Three fluid flow conduits are attached to the central section and two flow ports are defined in the central body with a flow passsage connecting the flow ports together. A control knob is attached to the central body and is used to move the central body from one orientation fluidically connecting one fluid conduit to a second fluid conduit to a second orientation fluidically connecting the one fluid conduit to a third fluid conduit. A flow selection plate having a plurality of notches defined therein is slidably mounted on the central section so various amounts of flow can be selected. The flow control valve can be used in a fluid circuit connecting a fluid source to various ones of a plurality of fluid flow driven subsystems.
