Abstract
In this work the authors present the results of their own researches regarding the achievement of a protection valve with corrugated pipe for gas furnaces. The valve with corrugated pipe was conceived in a way that in case of random disconnection of the gas blowpipe flame it couples out automatically the gas and a new firing could not be attained without human intervention. The valve was conceived for gas blowpipe with low yield usable at the refrigerating systems (type Fram 22) for vehicles.
