The invention relates to a thermal control valve (1), which comprises a valve house (9) having an inlet (10) and an outlet (11), which are separated from each other by means of a partition wall (12), with a seat (13) mounted in it, with which a valve body (15), against the force of a regulating spring (14), cooperates and which is influenced by a thermostat body (17), which in its turn is influenced by a spindle (18), the axial position of which and consequently also the position of the body valve and the contact pressure of the valve body against the seat respectively can be adjusted by means of a valve handle (19). According to the invention the one end of the thermostat body (17) is influenced by an overload spring (44), the one side of which is supported by the valve handle (19), by a larger compressive force than that of the regulating spring (14), said overload spring is mounted around the spindle (18) and with its other end supported by the spindle, the spindle is mounted in a movable way in relation to the valve handle (19) through the thermostat body (17) and the overload spring (44), in addition to its function as a thermal protection, is designed to compensate for the length reduction of the thermostat body (17), when the temperature is reduced, in order to exert a cooling security function. |
