Patent ID: 8602047

Claim:
A gas regulator fitting for a gas heater with a thermostatic safety pilot valve and a main valve that jointly serve both as a safety pilot and for splitting up the gas stream into proportions for a main burner and a pilot burner of the gas heater, with a valve causing a stepwise switching on and off that is arranged downstream of the main valve in the flow path of the gas stream for the main burner, and can be controlled by a switch, and is accommodated with further secondary functional elements in a housing ( 1 ), wherein the switch can be activated by a longitudinally movable rain ( 8 ) which leads out from the gas-conducting area of the housing ( 1 ) and whose position can be altered by metal bellows ( 9 ) connected by a capillary line ( 10 ) to a temperature sensor ( 11 ), wherein the metal bellows ( 9 ) are supported on an operating element ( 18 ) that influences their position and is activated manually and/or by a drive unit, wherein between the ram ( 8 ) and the operating element ( 18 ) one or more bimetal discs ( 17 ) are arranged whose overall height, which varies in the direction of movement of the ram ( 8 ) depending on the ambient temperature, can influence the position of the metal bellows ( 9 ).
