ELECTROMAGNETICALLY CONTROLLED BUTTERFLY THERMOSTAT VALVE

摘要

An improved cooling system for an internal combustion engine is disclosed. T he system utilizes an electronically controlled butterfly valve to control coolant flow between the engine and a radiator, thereby maintaining the engine temperatur e at a substantially optimum temperature. The valve includes a valve housing having an inlet port in fluid communication with an outlet port. A valve core is seated in t he housing for selectively opening and closing the outlet port. A driving mechanism is operatively coupled to the valve core for positioning the valve core between open and closed positions relative to the outlet port. A damping mechanism is coupled betwee n the driving mechanism and the valve core for preventing the driving mechanism fr om locking in the open or closed position during loading of the valve core with the housing and inlet or outlet ports.
