Rotary Valves For Multiple Gas Burners Patents (Class 137/905)
  • Patent number: 8844568
    Abstract: A multi-channel stepped motor operated gas adjusting valve includes a valve shell, a reduction motor, a locator, a gas flow distributor and a locator rotation angle detecting mechanism. The gas flow distributor has a disk which is tightly attached to a hard hollow washer. An inner wall of the valve shell is provided with locating ends corresponding to a group of locating nodes to form the locator rotation angle detecting mechanism. Each locating node is placed corresponding to a gas flow distribution groove of the same sequence. The inner wall of the valve shell is also provided with stopping blocks at a beginning state and an ending state of the locator. The valve enables accurate control by utilizing an action position feedback signal and a control circuit, and enables multi-position stepped adjustment on gas flow rate upon multi-channel gas passages simultaneously. The valve can independently cut the multi-channel gas passages.

  • Patent number: 8764436
    Abstract: In certain embodiments, a valve assembly can comprise a housing, a valve body, a first burner nozzle member and a second burner nozzle member. The housing can define an oxygen depletion sensor (ODS) inlet and a burner inlet. The valve body can be positioned within the housing and configured to rotate between a first position for a first fuel type and a second position for a second fuel type different from the first.

  • Patent number: 6318357
    Abstract: A gas burner configuration for cooking areas includes a multi-ring gas burner having an inner burner with laterally aligned gas/air mixture outlet openings and an annular outer burner, disposed at a spacing from the inner burner, with gas/air mixture outlet openings. A hand-operated gas fitting directs, meters, and shuts off the combustion gas, which can be fed to the multi-ring burner through separate pipelines. The gas fitting has valves and three gas duct branches to be opened and closed by the valves using an operating member adjustable to different setting positions. Two of the branches each provide a constant gas throughput, and the third provides variable gas throughput. One of the constant gas throughput branches is associated with the inner burner and is opened by one valve over and entire actuating path of the operating member. The other of the constant gas throughput branches and the variable throughput branch are associated with the outer burner and opened by other valves.

  • Patent number: 4819907
    Abstract: A gas tap for a gas cooker or hob includes a rotary disc valve (20) which controls the flow of gas from a gas rail (1) to a gas burner of the cooker or hob. To simplify the tap construction and facilitate manufacture, an external surface (2) of the gas rail (1) is used to form part of the tap housing and to provide the seating surface for the disc valve (20).
