The multi-piece housing includes a valve member of acetal resin and a cap member of high density polyethylene (HDPE) that has a flange that is ultrasonically welded to the gasoline tank and a coupling skirt that has minimal protrusion into the gas tank. The coupling skirt fits into upper a portion of the valve member and has a plurality of key-ways that receive inwardly projecting lugs of the valve member to couple the valve and cap members to each other. The valve and cap members are retained in the coupled position by resilient lock fingers of the valve member that engage notches in the bottom of the coupling skirt. The resilient lock fingers are cantilever beams that extend radially outwardly from an anchor spaced radially inwardly of an outer cylindrical wall of the valve member.Type: GrantFiled: June 20, 1997Date of Patent: October 5, 1999Assignee: Borg-Warner Automotive, Inc.Inventors: Peter G. Weissinger, Manuel D. Rosas

Patent number: 5901799Abstract: An apparatus for forcing a member or device, such as a sample tube or seismic or geological instrument, through a material such as soil along a selected line of action. The apparatus includes a derrick with first and second plates mounted thereto, the second plate having a locking dog extending through a hole therein for engaging the material, and the first plate being provided with a hydraulic cylinder or other device for forcing the member through the material. The first plate is also provided with an extruder head for releasably mounting the sample-containing sample tube thereto, and the hydraulic cylinder is provided with a plunger releasably mounted to the ram thereof for extruding the sample from the sample tube. The locking dog positively engages the material to provide an apparatus for transmitting the reactive forces resulting from forcing the member through the material to the material.Type: GrantFiled: June 7, 1995Date of Patent: May 11, 1999Inventor: Arthur S. Koenig

Patent number: 5765879Abstract: Locking arrangement of a fluid insertion connection between a fluid line and a connection member, in particular between a hydraulic line and a hydraulic cylinder, the fluid line having an insertion part at one end and the connection member being provided with an insertion opening which is open at the circumferential surface of the connection member and receives the insertion part of the line. Furthermore, locking means are provided, which engage on an abutment surface of the insertion part of the fluid line in order to prevent the insertion part of the line from being pulled out of the insertion opening.The locking means comprise a ring, which is positioned around the connection member at the position of the insertion opening and is movable with respect to the connection member.Type: GrantFiled: September 20, 1996Date of Patent: June 16, 1998Assignee: Applied Power Inc.Inventors: Leendert Willem C. de Jong, Willem Herman Masseling, Ben Kuiper, Aswin Leonard Koebrugge

Patent number: 5741084Abstract: A surgical instrument has a motor housing with a cylindrical member extending therefrom and has a pin projecting radially from the cylindrical member. A nose piece removably attached to the housing has a circular aperture which receives the cylindrical member and which has a channel within which the pin slides during attachment and removal. The nose piece includes a cantilevered arcuate spring arm that urges the pin along the channel toward a position at which the pin is wedged against a wall of the channel to force the nose piece into an operating engagement with the motor housing and retains the pin in the channel resisting detachment.Type: GrantFiled: January 17, 1997Date of Patent: April 21, 1998Inventors: Eddy H. Del Rio, William E. Anspach, Jr.

Patent number: 5667251Abstract: A coupling having an extending repositionable discharge tube for engagement with a discharge hose is mechanically lockably attachable to either of two different conventional waste water discharge outlets mounted on a recreational vehicle. Each of the waste water discharge outlets includes a set of four equiangularly spaced dogs and the set of dogs on each discharge outlet is differently configured. The coupling includes a different set of locking slots disposed at each end for receiving and lockingly engaging a corresponding one of the two sets of dogs. The discharge tube is relocatable to extend from one end of the coupling to permit engagement of the set of slots in the other end of the coupling with the set of dogs corresponding with the discharge outlet.Type: GrantFiled: September 14, 1995Date of Patent: September 16, 1997Inventor: J. David Prest

Patent number: 5580099Abstract: There is disclosed a quick connect/disconnect coupling for tubular elements such as hoses and the like, which uses a plurality of articulated jaws, with a retainer and a retainer clip. In this invention, each of the jaws has an axial groove extending from its inner edge, and the retainer sleeve has pins which extend into the grooves of the jaws. The axial groove in each jaw has a stepped width, with a greater width at the inner edge of said jaw, thereby permitting a limited rotational movement of said ring between its rearward and forward positions. The retainer sleeve also has an inner annular groove adjacent its inner face which receives a retainer clip to secure the assembly.Type: GrantFiled: April 3, 1995Date of Patent: December 3, 1996Inventor: Edward M. Eaton

Patent number: 5555929Abstract: A heat exchanger includes a first part made of metallic core material and having a first connecting portion, and a second part made of metallic core material and having a second connecting portion for connection to the first connecting portion. At least one of the first part and second parts is covered with a brazing layer, and the first and second parts are connected to one another by melting the brazing layer after the first part and the second part are assembled. The first connecting portion includes a fitting concave portion, and the second connecting portion includes a fitting convex portion which is press fitted into the fitting concave portion. The first connecting portion and the second connecting portion have the metallic core material exposed to each surface thereof so that each metallic core material directly contacts with one another when the convex portion is fitted in the concave portion.Type: GrantFiled: May 23, 1995Date of Patent: September 17, 1996Assignee: Nippondenso Co., LtdInventor: Morio Ishikawa

Patent number: 5397196Abstract: A connector system comprises a socket having at least one locking pin and a plug comprising a plug body and a locking ring having at least one slot along which the pin can move and an elastic member disposed at one end of the slot defining a first area in which the slot tapers and a second area in which the pin is selectively lodged. The aforementioned one end of the slot terminates at an abutment. The second area is wider than the pin and the first area so that the elastic member is retracted elastically when the pin enters the first area and returns to its initial position without being compressed by the pin when the pin is in the second area near the abutment. The elastic member of the connector system is a cantilever beam having a notch at its free end.Type: GrantFiled: July 16, 1993Date of Patent: March 14, 1995Assignee: Framatome Connectors InternationalInventors: Gerard Boiret, Thierry Quillet
