20150021504 | LOCKING MECHANISM FOR UNISEX BALL VALVE COUPLING - A unisex ball valve coupling includes an interface end that engages an interface end of a mating coupling half assembly. A valve of the coupling has a valve body, which has an open position in which fluid flow is permitted through the internal passage and a closed position in which the valve body closes off fluid flow through the internal passage. A valve shaft rotates with the valve body between the open position and the closed position. The valve shaft has a first surface. A blocking member is movable from a blocking position to a non-blocking position within the body portion. In the blocking position, the blocking member engages the first surface of the valve shaft to secure the valve body in the closed position and, in the non-blocking position, the blocking member does not engage the first surface of the valve shaft to permit opening of the valve. | 01-22-2015 |
20150097131 | LOCKING MECHANISM FOR UNISEX BALL VALVE COUPLING - A hydraulic valve coupling has an interlock mechanism that includes at least one blocking member within an interlock passage of a body of the valve coupling. The interlock passage has a first end opening to the valve shaft and a second end opening to an interface groove of the valve coupling. The at least one blocking member can be retracted within the interlock passage such that the valve coupling can be rotated and disengaged from a mating coupling. When the valve is in the open position, the at least one blocking member is positioned within the interlock passage such that it contacts the mating coupling and prevents rotation of the valve coupling relative to the mating coupling. The second end of the at least one blocking member can be shaped such that it is retracted as a result of contact with the mating coupling without assistance from a biasing mechanism. | 04-09-2015 |

20100051845 | Water Valve Apparatus - A water valve apparatus includes a housing and a control valve stem. The housing has a spacer to divide the interior space and a base with a plurality of water outlets formed thereon. The spacer has a first opening. The base has a second opening corresponding to the first opening. The spacer and base are interposed by a displacement track. The displacement track has at least one first anchor zone and one second anchor zone. The valve control stem runs through the first opening and second opening, and has a water stopper located in the first opening and an anchor ring movably coupled thereon. The anchor ring has at least an anchor stub in the displacement track. The valve control stem is operable easily to allow users to determine water supply. No excessive contact with water faucets is needed. Thus the risk of bacteria contagion can be minimized. | 03-04-2010 |
20120001110 | PLUG VALVE FOR GAS STOVE - A plug valve for a gas stove, consisting at least of a natural-gas nozzle, a propane-gas nozzle, a valve body, a cock, an adjusting rod, an O-shaped ring, a stop ring, a spring, a stop plate, a cover, a pair of screws, and a valve rod. The adjusting rod, the O-shaped ring, and the stop ring are disposed in the cock, the cock, the spring, the stop plate, the cover, and the valve rod are disposed in the valve body via the screws, the natural-gas nozzle or the propane-gas nozzle is disposed in the valve body. Switching between natural gas and propane gas, flow adjustment thereof are convenient, and no special tool is required, which make the invention suitable for a wide range of users. The plug of he invention is safe and reliable. | 01-05-2012 |
20100258754 | CONTROL VALVES AND METHODS OF FLOWING A MATERIAL THROUGH A CONTROL VALVE - Valves comprise a valve body having a gallery coupled to an inlet and an outlet to facilitate a fluid flow therethrough. A plug is moveably disposed within the valve body and a seat ring assembly may be coupled to the outlet of the valve body. At least one circular motion inducement feature is positioned in a portion of the valve body, the seat ring assembly, or both. The at least one circular inducement feature is configured to induce a circular motion in a fluid flow through the valve. Methods of creating a circular flow in a fluid flowing through a valve are also disclosed. | 10-14-2010 |

20080265196 | VALVES INCLUDING AN INSULATING MEMBER AND METHODS OF MANUFACTURE - Valves are provided that include a flowbody, a sealing element, and an insulating member. The flowbody has a channel and an outer surface. The sealing element is disposed in the flowbody channel. The insulating member surrounds the flowbody and includes an inner surface and an annular spacer extending radially inwardly therefrom and integrally formed therewith. The annular spacer is in contact with the flowbody outer surface to thereby form an airgap between the insulating member inner surface and the flowbody outer surface. Methods of manufacturing the valves are also provided. | 10-30-2008 |

20080258091 | FLOATING SLIT VALVE FOR TRANSFER CHAMBER INTERFACE - The present invention generally comprises a floating slit valve for interfacing with a chamber. A floating slit valve moves or “floats” relative to another object such as a chamber. The slit valve may be coupled between two chambers. When a chamber coupled with the slit valve is heated, the slit valve may also be heated by conduction. As the slit valve is heated, it may thermally expand. When a vacuum is drawn in a chamber, the slit valve may deform due to vacuum deflection. By disposing a low friction material spacer between the chamber and the slit valve, the slit valve may not rub against the chamber during thermal expansion/contraction and/or vacuum deflection and thus, may not generate undesirable particle contaminants. Additionally, slots drilled through the chamber for coupling the slit valve to the chamber may be sized to accommodate thermal expansion/contraction and vacuum deflection of the slit valve. | 10-23-2008 |
20090256095 | Locomotive Air Compressor Crankcase with Oil Drain Valve - A crankcase for a locomotive air compressor including a body defining an interior space, a port in fluid communication with the interior space of the body, a valve receiving portion adjacent to and surrounding the port, and an oil drain valve engaged with the valve receiving portion and having a flow passageway in fluid communication with the port. The oil drain valve has an open position and a closed position, such that the oil drain valve in the open position allows oil to flow from the interior space of the body through the flow passageway, and the oil drain valve in the closed position prevents the flow of oil from the interior space of the body through the flow passageway. A method for installing a locomotive air compressor having the crankcase and oil drain valve is also disclosed. | 10-15-2009 |

20090189106 | Tank opening-closing device - The tank opening-closing device is equipped with a tank opening forming member having a fuel path for leading fuel supplied from the fueling gun through the inlet to the fuel tank, a valve opening-closing mechanism having an opening-closing member and spring that closes in a state with the inlet sealed, and an opening-closing activation mechanism for opening and operating the opening-closing member. The opening-closing activation mechanism has an operating member pivoted at the tank opening forming member, and a pressing member for pressing the opening-closing member formed on the operating member, and is constituted so that by the operating member being pressed by the fueling gun and rotating, the opening-closing member is pressed by the pressing member and is rotated in the opening direction so as to open the inlet. | 07-30-2009 |
20140319393 | TWISTED SLIT VALVE - A self-closing twisted slit valve which is opened by compression inside a receiving tapered female orifice. For luer fittings, internal taper of a female luer fitting provides sufficient distortion of an asymmetrical valve to distort a closed, preferably planar slit to a patent fluid pathway. The slit may be opened by valve displacement into a female connector orifice or by being pierced by a blunt cannula. The valve may be effectively used for both needleless connectors and for needleless connector adapters. | 10-30-2014 |
