Gas burner control apparatus for operating a piezoelectric ignition system in conjunction with the gas valves
Abstract
Abstract A VALVE HOUSING INCLUDES A PILOT VALVE AND A MAIN VALVE MOVABLE ALONG A COMMON AXIS TO OPEN AND CLOSE THE VALVES. AN OPEATING MECHANISM FOR THE VALVES INCLUDES A CAM SUPPORT AND A CAM POST CONTACTING A CAM ON ONE SIDE OF THE SUPPORT. A HANDLE IS OPERATIVELY CONNECTED TO THE SUPPORT SO THAT IT CAN BE ROTATED TO A POSITION AT WHICH THE PILOT VALVE IS OPEN. THE BURNING OF THE PILOT VALVE CAUSES A LATCH TO HOLD THE SUPPORT IN THE ROTATED POSITION. REVERSE ROTATION OF THE POST, CAMS THE ROTATIONALLY LATCHED SUPPORT SO AS TO OPEN THE MAIN VALVE. A HANDLE IS CONNECTED TO ROTATE THE POST AND ALSO A RING GEAR. AXIAL DISPLACEMENT OF THE HANDLE AXIALLY MOVES THE GEAR TO A POSITION AT WHICH IT ENGAGES A GEAR ON A PIEZOELECTRIC LIGHTER, WHEREUPON ROTATION OF THE TWO GEARS ACTUATES THE LIGHTER.
