20090179089 | Variable shim for setting stroke on fuel injectors - A variable shim and valve seat assembly for applications in a solenoid actuated fuel injector includes a variable shim having a face, a valve seat having a top surface that interfaces with the face, and mating features integrated in the face of the variable shim and the top surface of the valve seat. The mating features provide axial displacement of the valve seat through rotation of the valve seat relative to the variable shim. The mating features may be ramped surfaces. The amount of seat displacement is dependent on the designed ramp angle, the number of ramps, and the degree of rotation. Once the desired valve stroke is set, the seat is welded to the injector body to achieve a leak free interface. Tight stroke setting tolerances can be achieved by applying an axial load to the seat during stroke setting and welding. | 07-16-2009 |
20100143763 | Laminated Plate Repeating Fuel Cell Unit For an SOFC Stack - An improved SOFC repeating fuel cell unit comprising three flat plates and a cell retainer. The three flat plates are metallurgically joined (brazed or laser welded) into a subassembly to which is added the fuel cell and cell retainer (which may also be joined as a second subassembly). Each flat plate performs a specific set of functions and can be optimized for those functions. Since the plates are flat and designed to overlap in loaded areas, the fuel cell unit is not prone to dimensional collapse which eliminates the internal reinforcements of the prior art design. The cell retainer is formed to provide a self-locating and locking feature for the fuel cell and decouples thermal stresses from the thin ceramic fuel cell. | 06-10-2010 |
