Publication number: 20040262916Abstract: A swivel outlet assembly serving as a conduit for fluid flowing from a vessel to a hose has a swivel outlet top that is rotably attached to a swivel outlet base. A bore in the swivel top is in fluid communication at an acute angle with a channel of the swivel outlet base. The swivel outlet base is configured for attachment to a vessel and the swivel outlet top is configured for attachment to a hose. The outlet swivel top can have an integral hose connector. The swivel outlet assembly optimizes the operator's freedom of movement, thereby providing greater versatility, as well as minimizing stress on the hose and connector, therefore reducing the expense associated with maintenance and repair.Type: ApplicationFiled: June 1, 2004Publication date: December 30, 2004Inventor: David Byron

Publication number: 20040239111Abstract: Normally, compressed air coupling plugs lock inside a coupling housing. Decoupling must consequently occur by releasing said plugs counter to the friction forces existing between the plug and the housing. This requires force and the plug may not relieved of pressure when decoupled. The invention works with a locking element (2) which is mounted in a coupling housing (1). The plug (5) and the locking element (2) are provided with reciprocally corresponding locking means (24, 52; 28, 56) whereby the locking element (2) can be pivoted for decoupling without the plug (5) pressing on the housing (1), thereby enabling large caliber tubing, such as those used with construction compressors, to be coupled by hand without tools.Type: ApplicationFiled: February 3, 2004Publication date: December 2, 2004Inventor: Hans Wuthrich

Patent number: 6817391Abstract: A sealed connector assembly (10) includes an insert (12) having an inner bore (26). A rotatable fitting (14) is supported in the inner bore (26). The rotatable fitting (14) has a fluid passageway (72) extending there through. The rotatable fitting (14) has a second passage (64) that extends transversely to the fluid passageway (72) to define an elbow. When the rotatable fitting (14) is inserted into the inner bore (26), a retaining ring (92) on the rotatable fitting (14) snaps into an inner locking groove (46) in an upper threaded portion (16) of the insert (12) and allows the rotatable fitting (14) to rotate in the insert (12). The retaining ring (92) abuts a lost motion device (38) and is compressed radially inward when the rotatable fitting (14) is moved axially inward. During any rotation or axial movement of the rotatable fitting (14) relative to the insert (12), a seal (90) remains in sealing engagement with the inner bore (26) of the insert (12).Type: GrantFiled: October 24, 2003Date of Patent: November 16, 2004Assignee: Moeller Marine ProductsInventor: Tony Riviezzo

Publication number: 20040189005Abstract: A female coupler suitable for use with a high pressure fluid is provided. The female coupler has locking members or balls adapted to be forced into engagement with a male coupler inserted into the female coupler by a sleeve or outer movable member. The sleeve is held by holding members or balls until the male coupler is inserted into the female coupler and a locking ball receiving recess formed in the exterior surface thereof is brought into a position for receiving the locking balls therein. Accordingly, the sleeve is prevented from moving to a position for forcing the locking ball into the locking ball receiving recess even if the male coupler is suddenly moved out from the female coupler, which is a problem that can occur in prior art female couplers. Further, the sleeve is provided with handle.Type: ApplicationFiled: March 24, 2004Publication date: September 30, 2004Applicant: Nitto Kohki Co., Ltd.Inventors: Toshio Mikiya, Koji Matsumoto

Patent number: 6742815Abstract: A fluid line connector assembly for connecting between two fluid transmission lines or between a transmission line and an appliance or other apparatus, such as a commercial fryer. The assembly includes a length of thin-walled, flexible tubing having helical corrugations extending therealong and opposing non-corrugated and generally cylindrical ends. A braided sheath extends along the exterior of the tubing and is secured at the tubing ends. A base ring is received on a tubing end and includes a first groove. An end fitting, including an interior passage having a second groove, is retained on and cooperable with the tubing end due to a retaining ring captured within a portion of each groove, allowing the end fitting to remain rotatable relative to the tubing. One or more o-rings are compressively positioned between the end fitting and the tubing end to form a fluid-tight seal therebetween.Type: GrantFiled: May 8, 2002Date of Patent: June 1, 2004Assignee: Dormont Manufacturing CompanyInventors: Todd R. McCurdy, Alfred Daniel Novak, Jr., Jerome J. Segal, Michael Lyon

Patent number: RE39695Abstract: A swivel joint comprises a tubular male member having at least first and second outer annular grooves formed on an outer surface, a tubular female member having at least first and second inner annular grooves formed on an inner recess, and a plurality of balls disposed in at least first and second annular races which are formed by the alignment of the first and second outer grooves with the first and second inner grooves when a first end of the male member is received within the recess of the female member. In addition, the radius of the first race is greater than the radius of an adjacent race closer to the first end of the male member, and the number of balls in the first race is just one more than the number of balls in the adjacent race closer to the first end.Type: GrantFiled: March 11, 2003Date of Patent: June 19, 2007Assignee: FMC Technologies, Inc.Inventors: Tep Ungchusri, Sergio A.
