Thermal management valve module with isolated flow chambers

A thermal management valve module, comprising:

• a housing;
• an isolating wall located in the housing that separates the housing into a first flow chamber and a second flow chamber that are isolated from one another;
• a first inlet on the housing that connects to the first flow chamber;
• a first outlet on the housing that connects to the first flow chamber;
• a second inlet on the housing that connects to the second flow chamber;
• a second outlet on the housing that connects to the second flow chamber;
• a first valve body rotatably positioned in the first flow chamber, the first valve body including a fluid pathway that, in a first rotational position, connects the first inlet and the first outlet, and in a second rotational position, prevents flow from the first outlet, and in an intermediate position, throttles the flow from the first inlet to the first outlet;
• a second valve body rotatably positioned in the second flow chamber, the second valve body including a fluid pathway that in a first rotational position of the second valve body connects the second inlet and the second outlet, and in a second rotational position of the second valve body, prevents flow from the second outlet, and in an intermediate position of the second valve body throttles the flow from the second inlet to the second outlet;
• and
• a single actuator that controls the positions of the first and second valve bodies, with the first valve body being movable by a first rotational distance between the first and the second rotational positions of the first valve body while the second valve body remains in one of the first or second rotational positions of the second valve body or rotates a second rotational distance that is less than the first rotational distance.
