  • Patent number: 11719350
    Abstract: A coolant flow control module, having a first outer housing, a first rotor located in the first outer housing, a second outer housing adjacent the first outer housing, and a second rotor disposed in the second outer housing. The second rotor is engaged with the first rotor such that the first rotor and second rotor rotate in unison. An actuator is connected to the first rotor, a first plurality of ports is integrally formed as part of the first outer housing, and a second plurality of ports is integrally formed as part of the second outer housing. The actuator rotates the first rotor and second rotor to at least one of a plurality of orientations such that fluid is able to flow through the first plurality of ports and the first rotor, and fluid is able to flow through the second plurality of ports and the second rotor.

  • Publication number: 20230139552
    Abstract: 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.

  • Publication number: 20230078460
    Abstract: A coolant flow control valve (CFCV) which includes an actuator having a microcontroller which drives an electric motor, such as a brushless DC motor. The motor drives a gear train, and the gear train drives a valve. The motor and gear train are used to rotate the valve to one or more positions, and thus direct coolant (passing through the valve) between ports. The valve is rotated to different positions to create various flow paths, such that coolant is directed between the different flow paths. The valve is a rotor having three different channels. The CFCV may also include a compound valve, where two valves are connected to and driven by one actuator. The valves may be of different shapes to accommodate inlet and outlet ports of various configurations.
