| 20090314980 | Seal-retaining valve for fluid metering device - A valve comprises a valve cartridge, a valve stem and a valve seal. The valve cartridge comprises a generally cylindrical cartridge body, a bore extending longitudinally through the cartridge body, and an outlet passage and intermittent inlet passages extending through a side wall of the cartridge body to intersect the bore. The valve stem comprises an elongate body configured to slide within the bore, and a neck and a seal channel circumscribing the elongate body. The valve seal is seated within the seal channel. The valve stem slides within the bore to move the seal channel past the inlet passages. Portions of the cartridge body between the inlet passages retain the valve seal within the valve channel until the inlet passages are open to the neck. In one embodiment, the inlet passages form a crenelated edge. In another embodiment, the inlet passages form a ported end. | 12-24-2009 |

| 20100276624 | SEAL WITH SEAL SUPPORT SHOULDER - A seal arrangement for a fluid device includes a seal member that is disposed in a first groove formed in a body and one or more backup members disposed in a second groove formed in the body, with a shoulder between the first and second grooves against which the seal member is supported. The fluid device may be any device that contains a fluid, such as, for example, a valve, a regulator or a fluid connector. The body may be, for example, a stem-like member or other device that is disposed in a bore and for which a fluid-tight seal is needed to prevent fluid flow along the annulus between the stem and the bore wall. The shoulder may be used, for example, to provide a rigid support for the seal member under pressure, in one embodiment supporting about half of the bulk material of the seal member under pressure. | 11-04-2010 |
| 20110057138 | Safety Valve for a Compressed Gas Reservior - A safety valve for a compressed gas reservoir has an exhaust duct that is connected to the compressed gas reservoir, and a sealing element, which is arranged to move within the exhaust duct, and selectively opens the exhaust duct to the outside depending on an operating phase. The exhaust duct has a greater cross-sectional area on the side facing away from the compressed gas reservoir than on the side facing the compressed reservoir, and a constriction on the side of the sealing element facing away from the compressed reservoir. | 03-10-2011 |
| 20120025122 | VALVE CARTRIDGE WITH LOBULAR KEY - A one-handle valve cartridge has one or more lobular keys formed on a housing of the valve cartridge. The lobular keys interface with keyways formed in a valve body. | 02-02-2012 |
| 20120032102 | MODULAR MEDIA CONTROL VALVE - A media control valve has a valve body having a media inlet and a media outlet and a plunger which is positioned within the valve body. The plunger is connected to a metering control assembly in the bore of the valve body and can be removed without disturbing the control assembly. A sleeve is positioned in the valve body between the valve body and the plunger. The sleeve includes an integral seal for sealing the valve to a flow device such as a base. The valve stem or post for housing the control knob may have metering marks for visually indicating the position of the plunger relative to the sleeve. The control knob on the valve is aligned with the metering marks on the valve body, whereby the valve opening may be calibrated by visual indication of the alignment of the metering marks with the lower edge of the control knob. | 02-09-2012 |
| 20120091384 | FLAT GASKET - A flat gasket arranged between a component that is fixed to the cylinder head and a housing that accommodates a camshaft adjuster. The flat gasket has a flat gasket body encompassing a surface to be sealed. On the gasket body, a convexity is formed, which encompasses the surface to be sealed and protrudes from the surface of the gasket body. | 04-19-2012 |
| 20120112115 | Sealing Arrangement For A Down Hole Valve - The present invention regards a sealing arrangement for a valve, comprising a valve element ( | 05-10-2012 |
| 20120286183 | MULTI-PIECE FLOW CONTROL APPARATUS FOR USE WITH FLUID VALVES - Multi-piece flow control apparatus for use with fluid valves are described. An example flow control apparatus described herein includes a sleeve having first and second ends, the first end including a lip. A valve plug tip is disposed in the sleeve and has a shoulder engaged with an inner surface of the lip. An insert is disposed in the second end of the sleeve and engaged with the valve plug tip to urge the shoulder of the valve plug tip against the inner surface of the lip. The insert has an opening to receive a stem of the valve. | 11-15-2012 |

| 20130214192 | COATED SEALS - The seal made between two surfaces is enhanced by forming a coating, such as a self-assembled monolayer of a functionalized fluorinated macromolecule, on one or both of the surfaces. | 08-22-2013 |
| 20140138568 | PURGING AND SEALING - REDUCTANT DELIVERY UNIT FOR SELECTIVE CATALYTIC REDUCTION SYSTEMS - A sealing device which is used as part of an injector in a reductant delivery unit (RDU), where the RDU is part of a selective catalytic reduction (SCR) system for injecting diesel exhaust fluid (DEF) into an exhaust system, used for controlling exhaust emissions. This invention improves the purging efficiency of the RDU, in addition to improving the sealing performance of the unit by reducing the fluid volume to be evacuated from the injector, and provides an additional sealing barrier to reduce the sealing load of the existing sealing elements. An additional sealing device having a ring seal and a stopper element (also referred to as a “plug”) is pressed into the upper valve body of the injector, which results in a reduced fluid volume that is left behind after a purging event, due to the reduced initial volume at the beginning of the purge. | 05-22-2014 |
| 20140239217 | VALVE ASSEMBLY - A valve assembly includes a plate defining a wall of a housing and a valve component included in the housing. A position of the valve component sets a state of the valve assembly. A channel is defined through the wall of the housing. A channel groove is defined along a wall of the channel. A sensor housing includes a sensor detecting a state of the valve assembly. A sensor groove is along the sensor housing A seal cooperates with both the channel groove and the sensor groove when the sensor housing is seated in the channel to both create a pneumatic seal between the sensor housing and the wall of the channel and retain the sensor housing in the channel. | 08-28-2014 |
| 20140264134 | VALVE SEAL ASSEMBLY WITH RELIEF VOLUME - An exemplary valve seal assembly is provided that includes a valve body with one or more relief volumes that may extend circumferentially and positioned in or adjacent one or both an upper and lower member of the valve body. A compression seal positioned adjacent an opening of a relief volume and a seal that is provided primarily in a volume between the upper and lower members. In an uncompressed state, the compression seal is maintained adjacent the opening of the relief volume. In a compressed state when the valve seal assembly compressively engages a valve seat, the compression seal is compressed against the relief volume, and may be either fully or partially compressed into the relief volume. A relief volume primary angle may be provided at a desired angle, and a seal retention volume primary angle may be provided at a desired angle. | 09-18-2014 |
