Abstract
A thermal management valve module having at least one flow chamber is provided, with one or more inlet and outlet ports connected to the at least one flow chamber. A first valve body is rotatably positioned in the at least one flow chamber, and includes a fluid pathway that connects a first port to the flow chamber, which allows separate or mixed flows, or blocks the flow, based on the valve body position. A second valve body is rotatably positioned in the at least one flow chamber, and includes a fluid pathway that connects a second port, which allows separate or mixed flows, or blocks the flow, based on the second valve body position. One or more actuators can be used to independently position the first and second valve bodies. An indirect connection, which can be an epicyclic gear arrangement, allows a single actuator to independently position both valve bodies.
