摘要: A stepped opening, diaphragm operated gas valve in which the operating pressure applied to the diaphragm is controlled by a spring biased pressure regulator and a delayed action pressure responsive actuator operating on an initial relatively low pressure acts, following a short delay, to increase the regulator spring bias, thereby to increase the controlled pressure and effect greater opening movement of the gas valve. An operative connection between the pressure responsive actuator and the regulator biasing spring includes means operative to transmit greater force and less movement during initial response of the actuator to the relatively low controlled pressure and greater movement and less force upon subsequent response of the actuator to the relatively greater controlled pressure developed as a consequence of the initial force and movement.

摘要: A fluid pressure-operated gas valve device has an adjustably biased pressure regulator which controls the operating pressure and is initially biased so as to effect a first predetermined valve opening step when operating pressure is applied and a delayed action pressure-operated actuator which acts, following a brief delay, to increase the regulator bias and effect a second predetermined valve opening step. Means are included to adjustably preset two combinations of the initial and increased regulator bias, with means to conveniently shift the biasing from one preset combination to the other to adapt to one or the other of two fuel gases.

摘要: A BIASED CLOSED GAS VALVE CONTROLLING A MAIN PASSAGEWAY IS MOVED OPENWARD BY A FIRST EXPANSIBLE CHAMBER AS IT EXPANDS. A RESTRICTED PRESSURE PASSAGEWAY HAVING A CONTROL VALVE THEREIN CONNECTS THE CHAMBER WITH THE UPSTREAM SIDE OF THE GAS VALVE AND A MORE HIGHLY RESTRICTED BLEEDOFF PASSAGEWAY CONNECTS THE CHAMBER WITH THE DOWNSTREAM SIDE OF THE GAS VALVE. THE PRESSURE IN THE CHAMBER THEREOF INCREASES AND THE GAS VALVE IS MOVED OPENWARD WHEN THE CONTROL VALVE IS OPENED. A BYPASS CONTROLLED BY A BIASED CLOSED PRESSURE REGULATOR VALVE PERMITS ADDITIONAL BLEED OFF SO AS TO LIMIT OPENING OF THE GAS VALVE TO A PREDETERMINED PARTIALLY OPEN POSITION. A SECOND, SMALLER, EXPANSIBLE CHAMBER HAVING A LOST MOTION OPERATIVE CONNECTION WITH THE PRESSURE REGULATOR OPERATES WHEN IT HAS EXPANDED A PREDETERMINED AMOUNT TO INCREASE THE CLOSING BIAS ON THE REGULATOR VALVE, THEREBY REDUCING THE BLEED OFF THROUGH THE BYPASS AND CAUSING THE GAS VALVE TO BE FULLY OPENED. A PASSAGEWAY CONNECTS THE SECOND, SMALLER, EXPANSIBLE CHAMBER WITH THE FIRST EXPANSIBLE CHAMBER AND INCLUDES A RESTRICTING ORIFICE TO DELAY EXPANSION OF THE SECOND SMALLER CHAMBER.

摘要: A gas burner control device including a biased closed, electromagnetically operated, fuel cutoff valve dependent upon electrical energy generated by a pilot burner-heated thermocouple to hold it open, and a biased open pressure responsive switch controlling the thermocouple-cutoff valve circuit, the switch being dependent upon a predetermined minimum gas supply pressure to close it and hold it closed, whereby either a drop in fuel supply below a predetermined minimum pressure or the extinguishment of the pilot flame effects closure of the fuel cutoff valve.
