The flow passage insert forms a flow path from a first end of the flow passage insert to a second end of the flow passage insert. The movable connector is disposed in fluid communication with the flow path of the flow passage insert and the movable connector has at least one orifice. The movable connector is movable between a forward fluid flow position that allows forward fluid flow within the flow path of the flow passage insert and a backward fluid flow position that prevents backward fluid flow within the flow path of the flow passage insert.Type: GrantFiled: May 27, 2010Date of Patent: September 18, 2012Assignee: International Engine Intellectual Property Company, LLCInventor: Erik Jordan Hansen

Patent number: 8256743Abstract: A female element quick coupling for releasably joining two pipes conveying a fluid under pressure and which receives a male coupling wherein the female element includes a latch movable relative to a body of the female element between a first position, in which it retains the male portion in a leaktight coupling position, and a second position, in which it retains the male portion in a position for purging a downstream pipe. The female element further includes a control member mounted to slide in an open bore in the body for causing the latch to move at least towards the second position. This female element includes a gasket for closing a gap defined between an outer face of the member and an inside face of the bore especially at high purging pressures.Type: GrantFiled: January 27, 2009Date of Patent: September 4, 2012Assignee: Staubli FavergesInventors: Alain-Christophe Tiberghien, Antoine Chambaud

Patent number: 8251346Abstract: Valves are provided for controlling flow along a fluid line that includes an outer shell and an inner housing slidably disposed therein that includes connector threads surrounding a boss on one end and a passage including a tapered region within the boss. A shaft within the valve includes a base coupled to the outer shell, a tapered sealing pin disposed within the tapered region, and a fluid passage extending through the base to outlets in the sealing pin. A connector may be threaded into the one end of the inner housing, thereby slidably engaging the connector threads, camming elements on the inner housing causing the inner housing to move helically from a closed position wherein the sealing pin engages the boss to seal the outlets and an open position wherein the inner housing is directed away from the sealing pin to open a fluid path through the valve.Type: GrantFiled: July 7, 2010Date of Patent: August 28, 2012Assignee: Infusion Innovations, Inc.Inventor: David K. Stroup

Patent number: 8196606Abstract: A coupling member is disclosed which includes a valve device that is axially movable between an open position and a closed position where the valve device closes an annular valve opening defined an outer valve seat portion and an inner valve seat portion. The valve device includes an outer annular sealing member and an inner annular sealing member. The inner annular sealing member includes an annular extending portion configured such that, when the valve device approaches the closed position, the annular extending portion sealingly engages the inner valve seat portion and is elastically bent to allow the valve device advance further to the closed position so that the outer annular sealing member positively engages the outer valve seat portion.Type: GrantFiled: November 13, 2007Date of Patent: June 12, 2012Assignee: Nitto Kohki Co., Ltd.Inventor: Hiroyuki Kitagawa

Patent number: 8186393Abstract: A nurse vehicle carries a supply of liquid chemicals or fertilizer for being applied by a sprayer vehicle. A fluid transfer conduit of the nurse vehicle has an end defined by a receptacle that is selectively connected to a complementary dimensioned insert defining an end of a fluid intake conduit of the sprayer vehicle. The receptacle and insert define a coupler assembly that includes an inflatable seal that surrounds the insert and locks the insert and receptacle together when inflated. Flow through the coupler assembly is controlled by first and second poppet valves, which are normally closed preventing flow through valve bodies of the receptacle and insert. Selective inflation of the seal and opening and closing of the poppet valves is automatically controlled in accordance with sequencing logic of an electronic controller so the seal is inflated before the valves are opened and remains inflated until the valves are closed.Type: GrantFiled: July 24, 2008Date of Patent: May 29, 2012Assignee: Deere & CompanyInventors: Daniel Joseph Huegerich, Travis Gene Funseth, Tonya Marie O'neal, Richard Allen Humpal

Patent number: 8186649Abstract: A pipe coupling capable of being safely connected and disconnected. The pipe coupling has a tubular housing (16), a first locking member (18), a pressing member (24), a valve member (30), and a second locking member (50) provided between the valve member (30) and the pressing member (24). When the housing is communicated with a fluid source with the pressing member (24) placed in a standby position (FIGS. 1 to 4), the second locking member is displaced by the valve member, which is displaced toward an open position by fluid pressure. In this process, the second locking member engages with the pressing member (24) before the valve member reaches the open position (FIG. 2), thereby preventing the valve member from reaching the open position and, at the same time, preventing the pressing member from being displaced to a pressing position. When the housing is communicated with the fluid source with the pressing member (24) placed in the pressing position (FIG.Type: GrantFiled: October 28, 2010Date of Patent: May 29, 2012Assignee: Nitto Kohki Co., Ltd.Inventor: Kazunori Aoki
