Patent number: 10513382Abstract: A front pull piercing valve assembly attached to a flexible container, whereby; when the wall of the flexible container is pulled into contact with a piercing element in the assembly, the contents of the container are dispensed by piercing the wall of the container and liquid flows through the valve assembly and directly into a container or through flexible hose or another connection to be dispensed. The valve assembly is configured in such a manner that during use it is filed with the liquid being dispensed thereby preventing the liquid in the flexible container from being exposed to air, namely, oxygen that often causes spoilage of certain liquids, such as wine.Type: GrantFiled: April 20, 2018Date of Patent: December 24, 2019Assignee: Liqui-Box CorporationInventor: James W. Johnson

Patent number: 9404595Abstract: The invention relates to a fluid circulation valve comprising a body (2) through which said fluid can pass, and a first and second shutoff means (3, 3?), arranged in series, in the direction of flow of the fluid, in said body and each able, by rotation of said means (3, 3?) with respect to said body (2) to occupy various angular positions, said valve further comprising a drive train allowing said shutoff means (3, 3?) to be driven off one and the same actuating motor, said valve being configured to: —over a first angular range of said first shutoff means (3) allow said fluid to be metered in a first outlet port (40) of said valve, said second shutoff means (3?) being in a position in which said first port (40) is wide open, —over a second angular range of said first shutoff means (3) allow said fluid to be metered in a second outlet port (42) of said valve, said second shutoff means (3?) being in a second position in which said second port (40) is wide open.Type: GrantFiled: May 7, 2013Date of Patent: August 2, 2016Assignee: Valco Systemes de Controle MoteurInventors: Mathieu Lallemant, Franck Girardon, Patrick Lebrasseur

Patent number: 8387651Abstract: A valve assembly for a faucet includes a spout, a valve stem, a first valve, and a second valve. The first valve is rotatably coupled to the valve stem upstream from the spout and is selectively positionable to control a flow of fluid from a fluid source to the spout. The second valve is rotatably coupled to the valve stem for selectively draining fluid from the valve assembly. Further, the second valve is coupled to the first valve such that when the first and second valves are positioned in a first operational position, fluid flows from the source through the spout, and such that when the first and second valves are positioned in a second operational position, fluid is substantially prevented from flowing from the source through the spout and residual fluid within the faucet is gravity drained from the faucet.Type: GrantFiled: December 3, 2008Date of Patent: March 5, 2013Inventor: David Michael Threlkeld

Patent number: 8312894Abstract: A vacuum cleaning machine has a cannister with an inlet port and at least two outlet ports. At least two filters are disposed inside of the cannister, one in pneumatic communication through each of the outlet ports. At least two valves are disposed outside of the cannister. Each valve is in pneumatic communication between a vacuum source and an outlet port so as to permit air to be drawn by the vacuum source from the inlet port simultaneously through the filters. A controller operates the valves to switch the filters from the vacuum source to ambient air so as to permit ambient air to be sequentially intermittently drawn through corresponding valves and filters into the cannister. Preferably, the controller includes a timing mechanism for setting the delay time of the sequential valve operation and a timing mechanism for setting the intermittent time of connection of each filter to ambient air.Type: GrantFiled: November 14, 2011Date of Patent: November 20, 2012Inventor: David L. McCutchen

Patent number: 8181757Abstract: An adjustable damping valve including an actuator, which exerts an actuating force on a valve body against the force of a spring to influence the throttle cross section which determines the damping force, where an emergency valve is connected in parallel with the throttle cross section with respect to the flow direction of the damping medium, where the two control surfaces of the valve body move in the axial direction and can thus can come to rest alternately on the two valve seating surfaces, and where the valve body is divided into two parts in the longitudinal direction, and each valve body assembly has its own control surface.Type: GrantFiled: September 28, 2007Date of Patent: May 22, 2012Assignee: ZF Friedrichshafen AGInventors: Steffen Heyn, Bernd Zeissner

Patent number: 7607588Abstract: Sink spray head with supply jet variation and flow rate regulation, comprising a body defining at least two distinct water supply areas in communication with a distribution chamber controlled by a diverting cut-off driven by means of two distinct selection keys accessible outside the body, a cut-off being also provided for the regulation of the water flow rate. The keys are operatively connected to the regulation cut-off.Type: GrantFiled: February 28, 2007Date of Patent: October 27, 2009Inventor: Fabrizio Nobili

Patent number: 6948512Abstract: A device and method for automatically flushing hydrants. The device is installed externally to an existing hydrant. The device comprises a nipple having an internally threaded collar for attaching the device to a hydrant outlet, a valve, a control for automatically operating the valve, and a lockable box containing at least the valve, the box having an outlet for allowing water from the hydrant to pass from the valve to the exterior of the box. The box functions as an enclosure and may be of any desired configuration.Type: GrantFiled: November 19, 2004Date of Patent: September 27, 2005Assignee: John C. Kupferle Foundry Co.Inventor: Daniel G. McKeague

Patent number: 6648006Abstract: Valve (1) with a through-going axial bore (4), a first spindle (5) axially displaceable in the bore (4), an elastic/flexible seal (10) placed at the one end surface (6) of the first spindle (5), at least two hollow connection branches (7, 8), each of which connects the valve to an outer coupling, said first spindle (5) in a first position forming a first annular sealing surface (9) between the outer surface of the seal (10) and the inner bottom (11) of the valve body which contains the outlet opening (29), and where the first spindle (5) lies coaxially inside a second axially displaceable and hollow spindle (12) lying in the bore (4), the end surface of which or parts thereof (13) form a second annular sealing surface (14) between the outer surface of the seal (10) and the inner bottom (11) of the valve body at a second position radially from the first annular sealing surface (9).Type: GrantFiled: October 1, 2001Date of Patent: November 18, 2003Assignee: Ostergaard Maskinfabrik A/SInventor: Jan Ostergaard

Patent number: 6382239Abstract: A diverter valve for controlling a fluid flow without the sudden hammering pressure changes normally found in fluid control systems, and a method for assembling the valve. The valve includes a modular valve body with two substantially identical sections, each with a valve seat, oppositely arranged. The valve body also includes a T-shaped connecting section connected between the end openings of the two other sections. A valve stem shaft in the valve body has two valve plugs facing together, with the two valve seats between the valve plugs, so that each valve plug moves against the flow of the fluid to a closed position. A valve actuator shifts the valve stem shaft axially between first and second positions so that first one plug is closed, and then the other. The second valve plug is removably attached to the shaft by means of a hollow stem connected to the second valve plug preferably by means of threads.Type: GrantFiled: December 9, 1998Date of Patent: May 7, 2002Assignee: Tri-Clover, Inc.Inventor: Robert D Zimmerly

Patent number: 6192923Abstract: An electromagnetic flow control device, or valve is provided. The valve uses two sets of stationary electromagnetic windings, with corresponding movable electromagnetic cores, which are completely contained within the flow stream of the valve. The movable cores are connected to a valve needle which can seal against a seat or open. The device is powered by electromagnetic energy only.Type: GrantFiled: February 9, 1998Date of Patent: February 27, 2001Inventors: J. Rodney Schexnayder, Charles Lowe
