Abstract
A gas regulator fitting is to be devised that prevents distortions of the temperature value to be regulated caused by ambient temperature fluctuations. Retrofitting without intervention into the gas-conducting space is also to be made possible. To that end, one or more bimetal discs (17) are arranged outside the gas-conducting space of the gas regulator fitting, between an operating element (18) for setting the required temperature and a longitudinally movable ram (8) whose position can be altered by means of metal bellows (9) which are connected to a temperature sensor (11) by a capillary line (10). The ram (8) protruding into the gas-conducting space activates a switch which controls a valve for regulating the gas stream to the main burner. The bimetal discs (17) are arranged in such a manner that their overall height, which is altered in the direction of movement of the ram (8) depending on the ambient temperature, can influence the position of the metal bellows (9).
