Linear proportional valve










Image Number 4 for United States Patent #6915958.

A valve assembly for automatically and proportionally controlling the flow of coolant fluid between an engine and a radiator for cooling the fluid heated by the engine in response to changes in the fluid temperature within a predetermined temperature range. The valve assembly includes a housing having a fluid chamber extending between opposing first and second ends. A radiator port extends between the radiator and the first end of the chamber. A bypass port extends between the engine outlet and the chamber. An engine port extends between the engine inlet and the chamber. A main valve is slidably received within the chamber for movement in and out of engagement with the first end of the chamber for closing and opening fluid flow between the radiator and the chamber. A secondary valve is slidably received within the chamber for movement with the main valve in and out of engagement with the first end of the chamber for opening and closing fluid flow between the bypass port and the chamber. A drive assembly is operatively coupled between the secondary valve and a central control for automatically and proportionally opening and closing the main and secondary valves in response to changes in the fluid temperature within a preselected temperature range.
