Abstract
The regulating valve has a heat responsive extension element which is prestressed and which extends crosswise of the gas line. The extension element biases the valve body into sealing engagement with the valve seat to maintain the valve in a normally closed position. Due to the slight deflection of the extension element, the thermal length variation of the extension element is transformed into an approximately 100-fold stroke of the valve body relative to the valve seat. The control accuracy of the valve is considerably increased.
