Abstract

A thermal management valve module is provided which includes a housing with at least one flow chamber. First and second valve bodies are rotatably positioned in the housing, and control the opening and closing of ports located on the housing. The first and second valve bodies include fluid pathways that allow flow through the first port and second port, dependent upon rotational positions of the valve bodies. First and second actuator shafts extend in the housing, the second actuator shaft is hollow and the first actuator shaft extends, preferably concentrically, through the second actuator shaft. The first valve body is rotationally fixed to the first actuator shaft and the second valve body is rotationally fixed to the second actuator shaft allowing separate positioning of the first and second valve bodies.
