The bushing includes a retaining groove for receiving a snap ring engageable with a retaining surface on the cartridge, thereby securing the cartridge within the end wall of the tank. The cartridge includes a fluid passageway which may be provided with a plurality of components, including push-to-connect tube or hose fittings, inlet check valves, pressure relief valves, or the like, by which the cartridge provides for communication with the interior of the air reservoir tank.Type: GrantFiled: August 2, 2001Date of Patent: October 14, 2003Assignee: Q3JMC, IncorporatedInventor: Richard C. Pickering

Publication number: 20030173780Abstract: A quick-connect coupling which includes a locking ring (20) disposed in an coupling body to co-operate with a catch surface on a tube fitted into the coupling. The ring is elastically deformable to go between an unlocking configuration and a locking configuration, in which at least one locking zone (30, 32) co-operates with the catch surface. To this end, the ring is provided with at least one unlocking bridge (22, 24) that protrudes through a slot in the body of the coupling. The ring is constituted by a strip that is plastically deformed to have at least the locking zone and the bridge. The ring forms a closed loop and has two ends (20A, 20B) which overlap, and which are suitable for sliding one over the other while the ring is being elastically deformed.Type: ApplicationFiled: January 24, 2003Publication date: September 18, 2003Inventors: Pascal Detable, Fabrice Prevot, Nicola Rigollet

Publication number: 20030168854Abstract: A quick-release fitting assembly has a male fitting and a female fitting. The male and female fittings are secured together by a retaining ring that is at least partially received in aligned first and second retaining grooves that are provided in the male fitting and the throat of the female fitting respectively. A water tight seal is provided by an O-ring that is retained in a sealing groove of the male fitting and radially compressed against the throat wall when the male fitting is inserted in the female fitting. The water tight seal remains substantially intact when the male fitting is rotated relative to the female fitting. In a preferred embodiment, the male fitting is removable from the female fitting by first compressing the retaining ring so that it no longer extends into the second retaining groove.Type: ApplicationFiled: February 5, 2003Publication date: September 11, 2003Inventors: Edward T. Lebreton, George S. Ellis

Publication number: 20030155763Abstract: A coupling for connecting hydraulic ducts has a first coupling element (1), in the form of a female coupling, with a receptacle (3) and a first locking face (10), and a second coupling element (2), in the form of a male coupling, The second coupling element (2) has an annular groove (9) that forms a second locking face (27) insertable into the receptacle (3). Several locking elements (10) are arranged in the annular groove (9). The locking elements (10) are held in the annular groove (9) and can be pivoted between a locking position and a releasing position. In the coupled condition of the coupling elements (1, 2), the first locking face (24) is axially supported on the second locking face (25). An unlocking sleeve (28) is displaceable between a locking position and a releasing position on the second coupling element (2). By moving the unlocking sleeve (28) from the locking position into the releasing position, the locking elements (10) are displaced from the locking position into the releasing position.Type: ApplicationFiled: February 17, 2003Publication date: August 21, 2003Inventors: Diethard Wolf, Jorg Altenrath, Recep Macit

Patent number: 6592151Abstract: A coupling assembly for connecting two members is provided that includes a first “male” member and a second “female” member. The first member includes a release sleeve moveably mounted thereon having a rigid release portion and a flexible sealing portion. The second member comprises at least one of an integral coupling member integrated into an apparatus, such as a pump, and an independent coupling member. Upon connection of the first and second members, the flexible sealing portion sealingly engages a mating surface on the second member to substantially inhibit the entry of contamination into an area between the first and second members when connected. The present invention provides an improved release sleeve that releases the male member from both an independent female member and an integral female member.Type: GrantFiled: September 26, 2001Date of Patent: July 15, 2003Assignee: Eaton Aeroquip, Inc.Inventors: David S. Densel, Stephen D. Hargett, Philip C. VanRiper, Todd J. Vogel

Patent number: 6588805Abstract: The present invention includes a pre-assembled, high-pressure coupling interface adapter for use with a non-threaded port of a female member. The adapter comprises a generally cylindrically shaped metal body including a central longitudinal channel and an inner and outer surface. The body includes an external segment having an external end and an internal segment having an internal end, the internal segment configured for receipt within the port of the female member. The inner surface of the body is configured to engage and secure one or more external features of a separate male coupling member. The present invention also includes a coupling assembly including a coupling adapter and a method for forming a female coupling assembly including an adapter.Type: GrantFiled: September 27, 2001Date of Patent: July 8, 2003Assignee: Eaton Aeroquip, Inc.Inventors: Matthew M. Persohn, Terry L. Karl, Richard Faber, Todd J. Vogel, David S. Densel, Philip C. Van Riper
