When a female coupler (116) is moved to the coupling position, a stop member (136) moves the plunger of a pressure relief valve (124) to an open position to allow fluid to be released from the female coupler (116) prior to coupling a male coupler thereto. A cam member (126), which is used to move the respective female coupler (116) from the operating position to the release position, can move away from the plunger when the female coupler (116) is in the coupling position as the pressure relief valve (124) is held open by the stop member (136).Type: GrantFiled: September 2, 2005Date of Patent: August 4, 2009Assignee: Parker-Hannifin CorporationInventor: Timothy T.

Patent number: 7565917Abstract: The invention provides a small, lightweight connector that is appropriate for the handling of fluids, a fluid supply apparatus that makes use thereof, a movable body, a fluid supply system, a connector connection method, and a connector separation method. A supply side connector provided on a fluid supply apparatus, and an inlet side connector, each have an inner cylinder which constitutes a connection part of both supply lines, and an outer cylinder which encloses the inner cylinder and which constitutes a connection part of both vent lines. A second supply valve is provided on the respective supply lines, and carries out switching between restriction and release of the flow of the fluid through the supply line by changing the position in the axial direction of the inner cylinder. A second vent valve is provided on the vent line of the inlet side connector, and carries out switching between restriction and release of the flow of the fluid through the vent line.Type: GrantFiled: April 22, 2005Date of Patent: July 28, 2009Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Takanobu Kamiya, Katsuhiko Akiyama, Takashi Maemura

Patent number: 7497231Abstract: A female coupling member is provided which includes locking members (32) for securing the female coupling member to a male coupling member (12) inserted into a receiving portion (22) thereof. The receiving portion has an inner surface (35-2) that slidingly engages a forward end outer surface (12-2) of the male member (12) when the male member is inserted into the receiving portion (22) and before it reaches a position where the male and female members are secured to one another by the locking members (32). The receiving portion further has a forward end inner surface (20-1(2)) that slidingly engages an outer surface (12-3) of the male member that is more rearward of the forward end outer surface (12-2) than the engaging portion (12-1) of the male member when the inward inner surface slidingly engages the forward end outer surface (12-2) of the male coupling member.Type: GrantFiled: April 13, 2007Date of Patent: March 3, 2009Assignee: Nitto Kohki Co., Ltd.Inventor: Takeya Sasa

Publication number: 20080271797Abstract: A thread to connect coupling comprising a female coupling half and a male coupling half is disclosed and claimed wherein the male coupling half includes a recess in the exterior of the male body which extends circumferentially therearound. The female coupling half includes a valve, a female body, and a female body extension affixed to the female body. The female body further includes a sliding sleeve movable with respect to the valve between a first position abutting and closing the valve and a second position opening the valve. The male body interengages the sliding sleeve and moves therewith during coupling and uncoupling. During uncoupling, the sliding sleeve is reliably positioned sealingly against the valve because the sliding sleeve is interlocked with the male body such that as the male body is withdrawn from the female body the sliding sleeve comes with the male body.Type: ApplicationFiled: July 18, 2008Publication date: November 6, 2008Inventors: Dennis Zeiber, Steve Wilkins
