Patent number: 8267435Abstract: A charge-air hose assembly includes a charge-air hose (2) for connecting to a pipe stub (4). The charge-air hose (2), in the assembled position, is pushed into the pipe stub (4) in such a way that overpressure occurring in the charge-air hose (2) presses the charge-air hose (2) radially outward against the radial inner wall (6) of the pipe stub (4). The charge-air hose (2) is assigned a latching device which, during the insertion of the charge-air hose (2) into the pipe stub (4), latches with the pipe stub (4) so as to axially fix the charge-air hose (2) to the pipe stub (4) in a predetermined axial position of the charge-air hose (2) relative to the pipe stub (4).Type: GrantFiled: January 4, 2010Date of Patent: September 18, 2012Assignee: ContiTech MGW GmbHInventors: Jörg Hellfeier, Hartmut Brill, Helmut Hoffmann, Peter Reichardt, Dieter Bamberger, Karl-Heinz Siebels

Patent number: 8240716Abstract: A quick connector coupling for use with a fluid line includes a connector body defining a through bore extending from a male reception end of the connector body. The connector body is adapted to operably receive a male member extending through the male reception end of the connector body into the bore. A retainer is releasably coupled to the connector body. The retainer is movable relative to the connector body from an unlatched position to the latched position only when the male member is fully inserted into the body. A separable indicia element is releasably engaged to the retainer and is removable from the retainer only when the retainer is in the latched position.Type: GrantFiled: August 3, 2009Date of Patent: August 14, 2012Assignee: TI Group Automotive System, LLCInventors: Jim Kerin, Richard M.

Patent number: 8226128Abstract: A releasable nut-free C-clip secured pipe fitting includes a pipe to be jointed, a C-clip, a sealing ring, and a pipe fitting. The pipe has a jointed end forming a circumferential groove for receiving the C-clip. The C-clip is a ring like member having an opening, which allows for expansion and contraction of the C-clip so as to allow the C-clip to be disposed in a converging surface formed on an inside wall of the pipe fitting. The sealing ring is received in a sealing ring groove defined in the inside wall of the pipe fitting. The pipe fitting has a tube end forming a holding bore having an inside diameter smaller than a diameter of the converging surface. The tube end of the pipe fitting forms openings through which a tool can extend into the pipe fitting to contract the C-clip for releasing the C-clip and the pipe.Type: GrantFiled: August 11, 2010Date of Patent: July 24, 2012Inventor: Ming-Yi Lee
