Abstract:
1. A circulating coolant cooling system for an internal combustion engine, comprising: a multifunction valve having a plurality of inlet ports and output ports, a first moveable plate, a second moveable plate and an operator for moving the plates to selectively open and close passageways interconnecting the inlet and output ports, the first moveable plate selectively restricting and unrestricting fluid flow through a first one of the plurality of inlet ports and first and second ones of the plurality of output ports, the second moveable plate selectively restricting and unrestricting fluid flow through second and third ones of the plurality of inlet ports; a radiator connected between one of said inlet ports and one of said outlet ports; a pump for pumping coolant, the pump connected between one of said inlet ports and one of said outlet ports; a water jacket in an engine block, the water jacket connected between one of said inlet ports and one of said outlet ports; a water jacket in an engine cylinder head, the cylinder head water jacket connected between one of said inlet ports and one of said outlet ports; a heater core for a heater in a passenger compartment, the heater core connected between one of said inlet ports and one of said outlet ports; a degas bottle to capture and retain gases entrapped in the coolant, the degas bottle connected between one of said inlet ports and one of said outlet ports; and a heat exchanger for heating and cooling lubricating oil, the heat exchanger connected between one of said inlet ports and one of said outlet ports, wherein the multifunction valve interconnects the engine and cooling system components and operates to permit and inhibit flows of coolant as necessary for thermal management of the engine.
