Publication number: 20100062100Abstract: The present invention is directed to an injection molding valve configured to prevent the leaking or stringing of injected thermoplastic from the valve. The valve includes a housing having a first bore along a length thereof and a second bore intersecting the first bore. A rotatable member is inserted through the second bore and is in communication with a lever for the actuation thereof. The rotatable member includes a hole therethrough such that when the hole is aligned with the first bore, thermoplastic may travel freely through the first bore. The second bore further includes at least one groove in communication with a port for receiving injected thermoplastic. The injected thermoplastic is hardened to form an seal therein and configured to prevent thermoplastic from leaking out of the valve housing.Type: ApplicationFiled: September 5, 2008Publication date: March 11, 2010Inventors: John J. Hahn, Larry A. Schmitt

Publication number: 20100032490Abstract: The invention relates to a valve (3) that comprises a housing (20) and a thermostatic member (52) having a mobile piston (58) that carries a plug (76) for controlling the fluid flow between two accesses to the housing. In order to simplify the manufacture and the maintenance of the valve, inter alia, a hollow body (54) bearing the thermostatic member is adapted both to be rigidly connected to the fixed portion of the thermostatic member so that the piston can extend inside the inner chamber (64) of the body and so that the plug controls the fluid flow through said chamber, and to be received and sealingly blocked in an inner volume (V20) of the housing so that the fluid cannot flow between the two accesses through the chamber, while a thermostatic assembly (50), defined by the bearing body and the thermostatic member connected together, can be urged as a whole into the inner volume of the housing.Type: ApplicationFiled: December 21, 2007Publication date: February 11, 2010Applicant: VERNETInventor: Lionel James Mabboux

Publication number: 20100025050Abstract: A temperature-activated valve for a conventional fire sprinkler utilizing a hyperelastic single-crystal shape memory alloy is described. The shape-memory element expands as it is heated, forcing a bolt to break, thereby opening the sprinkler valve. The devices described are less susceptible to accidental breakage than conventional actuators, and have fewer moving parts. Transition temperature of the shape memory alloy can be tuned to a narrow range.Type: ApplicationFiled: January 24, 2008Publication date: February 4, 2010Inventors: Alfred Johnson, Roger Gilbertson, Valery Martynov

Publication number: 20100001223Abstract: A diaphragm membrane (212) is disclosed that has a shape that spring loads a diaphragm during assembly to provide a default position for the diaphragm. The diaphragm membrane (212) is made from a resilient material. The diaphragm is spring loaded during assembly to provide a force that returns the diaphragm to the default position.Type: ApplicationFiled: March 15, 2006Publication date: January 7, 2010Applicant: Norgren, GmbHInventor: Andreas Tschurtz

Patent number: 7637443Abstract: A fuel injector, e.g., for fuel-injection systems of internal combustion engines in motor vehicles, includes a valve housing including a sleeve-shaped housing section; and a solenoid, situated on the housing section, having a coil brace, magnetic coil and magnetic cup. To protect the magnetic coil from salt fog that arises under specific environmental conditions and penetrates along the contact areas of solenoid and housing section, the coil brace with wound magnetic coil is completely enclosed on all sides by a one-piece plastic coat.Type: GrantFiled: October 5, 2005Date of Patent: December 29, 2009Assignee: Robert Bosch GmbHInventors: Martin Scheffel, Andreas Glaser, Jens Pohlmann, Thomas Gerschwitz, Christina Gerescher

Patent number: 7634856Abstract: An assembly method includes a step of press-fitting a second valve 27 to a valve shaft 29 to which a first valve 25 is press-fitted and secured while measuring and adjusting a distance L2 so that it becomes equal to a distance L1. Thus, the first valve 25 and second valve 27 are press-fitted to the valve shaft 29 and those components are swaged together so that the first and second valves are secured to the valve shaft, and oil is placed in a press-fitted portion. When components, such as the first valve 25, are sintered parts, oil contained in the sintered parts themselves is used for increasing a joining force that occurs in the press-fitted portion.Type: GrantFiled: October 25, 2004Date of Patent: December 22, 2009Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Katsunori Takai, Sotsuo Miyoshi

Publication number: 20090283613Abstract: An elastic membrane is provided for use in a flow-control device comprising a housing with a seat of a predetermined shape and dimensions for the membrane such that when the membrane is mounted in the seat, the membrane is deflected by a pressure differential between its two opposite sides. The elastic membrane has a predetermined shape and dimensions matching the seat and is made of foamed elastomer with closed cells of predetermined cell density and morphology.Type: ApplicationFiled: August 9, 2006Publication date: November 19, 2009Inventor: Tzvi Barkai

Publication number: 20090277177Abstract: A method for fabricating a fuel nozzle assembly includes providing a nozzle portion including a fuel passageway defined about a center axis of the fuel nozzle assembly. A longitudinal axis of a first peg is oriented to intersect the fuel nozzle assembly center axis such that a first plane is defined. The first peg defines a first opening having a centerline intersecting the first peg longitudinal axis and obliquely oriented with respect to the first plane. The first peg is coupled in flow communication with the fuel passageway such that the first peg extends radially outward from the nozzle portion and such that the first opening is configured to direct a flow of fuel in an oblique direction with respect to the fuel nozzle assembly center axis to facilitate fuel mixing.Type: ApplicationFiled: May 9, 2008Publication date: November 12, 2009Inventor: William Kirk Hessler
