Patent number: 6893052Abstract: A connecting arrangement for coolant lines includes a first coupling piece, connected seal-tight to a first line endpiece, and a second coupling piece, connected seal-tight to a second line endpiece. The coupling pieces each have radially extending sealing surfaces on the side facing toward the other coupling piece. A sealing ring is mounted between the sealing surfaces. The coupling pieces are joined to each other via a screw arranged laterally offset from the sealing surfaces so the line endpieces connect to each other via respective bores in the coupling pieces. A form body between the coupling pieces arranged at a spacing from the screw on the side facing away from the sealing surfaces is configured so a lever action occurs when the coupling pieces are joined to each other leading to a uniform pressing together of the sealing ring between the sealing surfaces of the coupling pieces.Type: GrantFiled: February 5, 2004Date of Patent: May 17, 2005Assignee: ContiTech Kuehner GmbH & Cie. KGInventors: Andreas Wildermuth, Mike Eismann

Patent number: 6890005Abstract: A tubular connection for centering a tube within a female connecting block that has a throughbore with a chamfer, wherein a transition surface is defined between the chamfer and the throughbore. The tube has an upset bead, a tapered portion narrowing from the upset bead, and an end-form extending from the tapered portion, the end-form having an annular groove with an O-ring therein. The connection further includes a device for securing the tube within the female connecting block whereby the upset bead of the tube is caused to abut the female connecting block. The tube locates inside the female connecting block such that the end-form seals via the O-ring inside the throughbore of the female connecting block and the tapered portion of the tube sealingly engages against the transition surface of the female connecting block to keep the tube centered within the female connecting block and to form a secondary fluid-tight seal.Type: GrantFiled: October 29, 1999Date of Patent: May 10, 2005Assignee: Hutchinson FTS, Inc.Inventor: Jerry H. Chisnell

Patent number: 6860290Abstract: A rapid coupling system for establishing a connection of at least two pressurized lines in a pressure sealed manner is provided. A first coupling plug element has an operating mechanism, including a journal, in a connecting block thereof. A second coupling socket element is adapted to be connected to the first coupling element in a pressure sealed manner. A control unit is arranged in a socket element connecting block and includes a displaceable plunger having at least one cam. A pressure relief unit is connectable to at least one of the pressure lines via a pressure relief connection. When the first and second coupling elements are connected to one another, the journal of the operating mechanism displaces the control plunger, causing at least one cam of the control plunger to engage the pressure relief unit.Type: GrantFiled: April 17, 2003Date of Patent: March 1, 2005Assignee: Tema Marketing AGInventor: Per Knuthson

Patent number: 6860516Abstract: A channel tube coupling structure for an anti-pollution type endoscope which can easily and smoothly couple a multi-lumen type channel tube extending from a base end of an outer sheath with tubes on a side of the endoscope and separate the multi-lumen type channel tube therefrom. At a side surface in a vicinity of the base end of the channel tube, side holes communicate with a plurality of tubes that are formed so as to be shifted from one another in an axial direction. A coupling hole, where the base end portion of the channel tube is loosely inserted thereinto and freely removed therefrom, provides a space in a radial direction between the channel tube and the coupling hole. Annular sealing members are provided which seal portions between the respective side holes, in a state where the base end portion of the channel tube is inserted into the coupling hole.Type: GrantFiled: December 4, 2002Date of Patent: March 1, 2005Assignee: PENTAX CorporationInventors: Teruo Ouchi, Kazuyuki Yamamoto
