Patent number: 7617851Abstract: A fuel vapor recovery system of a vehicle has a fill pipe inlet assembly located at a distal end of a fuel tank fill pipe. The inlet assembly has a cylindrical wall defining an elongated cavity divided axially into upstream and downstream regions by a restrictor plate which carries a hole for close receipt of a fuel supply nozzle of a remote fuel pump. During refueling of the tank, fuel vapor flows from the tank via a recirculation tube and into the inlet cavity of the fill pipe to become entrained into the flowing liquid fuel as oppose to being released to atmosphere. The fuel vapor enters the upstream region at an aperture carried by the wall disposed immediately upstream from the restrictor plate and downstream from a hood. The hood limits vapor release to atmosphere and draws the vapor downstream through a port carried by the restrictor plate for entrainment of vapor into the liquid fuel in the downstream region.Type: GrantFiled: May 28, 2004Date of Patent: November 17, 2009Assignee: TI Group Automotive Systems, L.L.C.Inventors: Timothy J.

Patent number: 6691738Abstract: The present invention is directed to a filler assembly for dispensing liquid to and from a container capable of storing an indicated liquid. The filler assembly has a portable part and a stationary part cooperating to provide a sealed dispensing means for communicating an indicated liquid from an indicated liquid source to a container and for safely communicating the indicated liquid from the container to another location. The portable part and the stationary part are adapted to sealably mate together and further provide means for preventing misassembly of the two parts. The portable part provides dispensing means capable of communicating the liquid from the stationary part to a remote location. The stationary part is adapted to further sealably mate and communicate with a container capable of storing an indicated liquid.Type: GrantFiled: November 21, 2001Date of Patent: February 17, 2004Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Wen-Chang Kuo, Szu-Yao Wang, Wen-Hsiang Tseng

Publication number: 20040011410Abstract: A valve is disclosed for dispensing a flowable material. The valve has a first chamber (40) at a first pressure wherein said first chamber (40) defines an outlet (28) in communication with said first chamber (40). A second chamber (42) is at a second pressure. The valve has a stop (18) indexed against a third pressure, operating to selectively place the first chamber (40) into communication with the second chamber (42). The stop (18) is operative to connect the second chamber (42) to said first chamber (40) when the first pressure is less than the third pressure. The valve includes a vent (520) for venting the second chamber (42) when flowable material is removed.Type: ApplicationFiled: April 14, 2003Publication date: January 22, 2004Inventors: Hal C. Danby, Julian Swan, Mark E. Williamson

Patent number: 6648016Abstract: A valve assembly for admitting a tube or fuel into a vehicle fuel tank is disclosed. The valve assembly has a fixed housing with an inlet, an outlet, a middle section and an inner surface with an opening. At least one projection depends from the inner surface between the inlet and the outlet. The projection deflects the tube toward and through the opening. A piston element, which is slidably mounted to the housing, is normally urged in a direction to close the outlet and the opening until the tube or fuel urges the piston element in an opposite direction.Type: GrantFiled: January 24, 2002Date of Patent: November 18, 2003Assignee: Alfmeier CorporationInventors: Markus T.

Patent number: 6637477Abstract: A filler neck for the fuel tank of a motor vehicle. The inventive filler neck comprises a housing (12, 14) which has an outer closure (30) that can pivot between a closed and opened position and which has a second closure element (50) that is accommodated inside the housing. Said second closure element is interactively connected to a ventilating valve (16) which, in order to equalize pressure, automatically opens in the instance of excess pressure inside the fuel tank and opens when inserting the dispensing nozzle (100), said dispensing nozzle causing the closure element (50) to swivel open. The inventive filler neck is characterized by a lever (1) which is pivotally mounted on the housing (12). Said lever is actuated by the dispensing nozzle (100) when the same is inserted, and opens the ventilating valve (16) before the dispensing nozzle (100) causes the second closure element (50) to swivel open.Type: GrantFiled: April 5, 2002Date of Patent: October 28, 2003Assignee: Tesma Motoren und Getriebetechnik GmbHInventor: Bernhard Maier

Patent number: 6634396Abstract: The object of this invention is to improve safety by preventing the leakage of liquid caused by the internal pressure of a container. A liquid path plug in which a pipe is provided in the lid section of the plug, and a gas path plug which does not have a pipe are attached to openings of the container. The engaging groove section is formed on the end surface of the liquid path cap which closes the through hole provided in the liquid path plug section of the liquid path plug. The engaging protrusion section and the engaging hole section are formed on the end surface of the gas path cap which is provided in the gas path plug section of the gas path plug and closes the through hole. The gas path cap is detached by engaging the engaging pin of the detaching fixture on the engaging hole section of the gas path cap and by turning the gas path cap.Type: GrantFiled: October 10, 2001Date of Patent: October 21, 2003Assignee: Surpass Industry Co.

Patent number: RE40051Abstract: A self-venting drain valve is rotatably and slidably mounted to a filter assembly through an internally threaded base. The drain valve comprises a homogenously formed one-piece unitary valve body including a tubular valve stem portion and a valve knob portion. The valve stem portion includes a wall member defining an internal passageway provided with axially extending air vent openings through which ambient air can enter a filter housing through the internal passageway, and drain holes through which water is drained from the filter housing and the internal passageway. The air vent openings are formed through an upper portion of the wall member and are open to a top edge thereof, while the drain holes are formed through the lower portion of the wall member. The liquid drains from the filter housing through the internal passageway and the drain holes, then exits into the valve knob portion.Type: GrantFiled: March 18, 2004Date of Patent: February 12, 2008Assignee: Wix Filtration Corp LLCInventors: Willie L.
