ABSTRACT:
A thermally responsive fluid control valve device which is particularly adapted for control of an air operable clutch. The valve device includes a housing which is adapted to be positioned adjacent a conduit which is a part of a system through which coolant fluid flows in a cooling system of an internal combustion engine. The valve device includes a thermally responsive actuator member which is adapted to be positioned within a conduit within which coolant fluid flows. The thermally responsive actuator member has a portion operable upon a movable valve element which is within the housing and which controls flow of air through the housing. The movable valve element is also operable by air at suitable pressures within the housing.
