Patent attributes
A multi-level rotor for a coolant flow control valve assembly, which accommodates an increased number of inlet ports, outlet ports, and flow channels using a single rotor located in a housing, enabling a larger number of flow configurations. The housing includes nine ports which may function as an inlet or an outlet, which facilitates different flow configurations. For a thermal management system, reduced cost and less space utilization is achieved by a reduced number of valves, where the multi-level rotor is able to fluidically connect multiple inlets/outlets. This enables different flow configurations, depending on the degree of rotation. The channels at different levels are sealed from each other within the housing. The flow channels are manufactured into a single entity, therefore always having the same positional accuracy relative to each other when the rotor is repositioned.
