ABSTRACT:
A multi-port rotary valve used to distribute coolant to an engine cooling system comprises a valve body having a plurality of outlet ports for directing coolant flow to a radiator circuit, a heater circuit, and an auxiliary circuit. An internal gear driven rotary disc includes a gear driven mechanism located on an inner circumference of the rotary disc. The rotary disc includes two apertures positioned on a top surface of the rotary disc for regulating predetermined flow paths and flow rates to the plurality of ports. An inlet housing body which includes an inlet port mates with the valve body and encases the rotary disc. An actuator which is coupled to a drive gear mounted internal to the inlet housing body is responsive to a control signal for transmitting a torque to the internal drive gear for rotating the rotary disc to regulate coolant flow.
