| 20090092936 | PRESSURE REGULATOR WITH BLEED ORIFICE - A pressure regulator having a housing that defines a gas inlet, a gas outlet, and a reference pressure connector. A diaphragm is provided in the housing, where the diaphragm defines, at least in part, a reference pressure chamber. In some illustrative embodiments, the reference pressure connector fluidly references the reference pressure chamber to a first pressure via a first orifice, and to a second pressure via a second bleed orifice. A gas valve incorporating a pressure regulator is also disclosed. | 04-09-2009 |
| 20100015560 | PILOT BURNER - An improved pilot burner includes an orifice plate defining a central orifice for metering a supply of gas and a gas tube. The gas tube includes a tube wall and defines a supply opening at a first end. The orifice plate is positioned within the gas tube at the supply opening, and the tube wall is crimped around the orifice plate to secure the orifice plate to the gas tube. The pilot burner also includes a burner tube having a first end for receiving a first end of the gas tube. The burner tube further includes a second end defining a flame opening. In another embodiment, a clip is used to secure the gas tube and the burner tube to a bracket. | 01-21-2010 |
| 20100282988 | SINGLE COIL REDUNDANT VALVE - A single magnetic coil floating plunger redundant gas valves is disclosed. In an illustrative embodiment, the valve may include a first plunger tube, a second plunger tube spaced a distance from the first plunger tube, a magnetic coil disposed about at least part of the first plunger tube, a first plunger disposed within the first plunger tube, and a second plunger disposed within the second plunger tube. The first and second plungers may be operatively coupled to first and second valve members. Activation of the magnetic coil may result in the first and second plungers being suspended in the plunger tubes without a hard mechanical plunger stop to selectively open corresponding valves or other actuatable components, as desired. | 11-11-2010 |
| 20110045423 | GAS PILOT BURNER ASSEMBLY - A pilot burner assembly for easy removal of a thermo-electric or other device is disclosed. In an illustrative embodiment, a burner tube, thermo-electric device, and/or spark source are retained in a desired position via a bracket and resilient clip. The bracket may include retention features built into the bracket to help aid in the positioning of the burner tube, thermo-electric device, and/or spark source. The burner tube, thermo-electric device and/or spark source may include retention features that are configured to engage corresponding retention features in the bracket, when desired. The resilient clip may bias the retention features of the burner tube, thermo-electric device and/or spark source against corresponding the retention features of the bracket. One or more of the burner tube, thermo-electric device and/or spark source may be removed from the bracket by overcoming the bias force provided by the resilient clip to disengage the retention features of the burner tube, thermo-electric device and/or spark source from the corresponding retention features of the bracket, and sliding the component out of the bracket. | 02-24-2011 |
