Abstract (en)
[origin: EP0269509A1] According to the invention the said valve comprises a rotary actuating knob (1) and a bubbling diaphragm mechanism (8, 4) connected to a bulb and reacting to an increase in temperature of the combustion products. It also comprises a cam (2) mounted so as to rotate about its axis AA' under the action of the said knob which cooperates with the actuating rod (7, 21) of the gas inlet shutter (6) and which can also move in translation over the said axis AA' under the action of the bubbling diaphragm mechanism (8) in order to cause it to be released from the actuating rod (7) of the shutter and to make the apparatus safe. Application to hot water apparatuses without a permanent pilot flame. <IMAGE>
