137315410 | Tool for applying or removing valve or valve member | 8 |
20130333769 | Combination Tire Valve Core Removal and Fluid Fill Tool - A tool attachable to a valve stern of a tire grips and removes the valve core from the valve stern prior to introduction of sealant through the tool into the tire. Subsequently, the valve core, which has been stored in the tool, may be reinserted into the valve stem. An external pressurized gas source may then be attached to the tool so that gas may be injected through the tool and the valve stem of the tire into the tire. | 12-19-2013 |
20130333770 | MEANS FOR MOUNTING CHECK VALVE INTO HOUSING INCLUDING FLUID PASSAGE THEREIN - There is provided a means for mounting a check valve into a housing including fluid passages therein that can secure a closing property between a valve body and a valve seat by preventing the deformation of the valve seat, can prevent the rattling of the check valve relative to the housing including fluid passages therein and can ensure the flow rate of fluid necessary at the time of start-up. The check valve | 12-19-2013 |
20140158221 | Press Device for Valve Maintenance - A press device for valve leakage abatement while piping system maintenance is being performed is disclosed herein. Essentially, the device comprises a frame that can clamp down and provide pressure (and therefore seal) to the valve. The design further includes a vent or a test port to assist in determining if a pipe freezing apparatus is working. Also disclosed is a system for providing pipe maintenance to a water supply line wherein one or more pipe freezing apparatuses are employed in addition to the press device. | 06-12-2014 |
20150075643 | FLUID EXTRACTOR DEVICE AND KIT - A fluid extractor device including a ring with a circumference capable of fitting around an oil filter; a bracket affixed to the ring; and a valve including a base attached to the bracket, an extendable pin extending through the base, and a vacuum extension extending perpendicularly from the base and terminating in a vacuum aperture. | 03-19-2015 |
20150369385 | SPRING-CAPTURE ASSEMBLY FOR A SPRING-BIASED MECHANISM AND PRESSURE RELIEF VALVE INCLUDING SAME - A spring capture assembly is provided for securing a compression spring of a spring-biased mechanism, such as a spring-biased pressure relief valve, to permit disassembly of the mechanism without risk of damage or injury associate with rapid resiling of the spring from a compressed state. The assembly includes a tool, a housing having an opening for admitting passage of the tool and capturing the spring at one end, a spring retainer, and a compression spring mounted within the housing and captured at one end by said housing and toward an opposite end by the spring retainer. The tool is adapted for mating with the spring retainer and the housing to compress the spring therebetween. The spring capture assembly may be incorporated into a pressure relief valve for venting pressure and/or vacuum from a pressure vessel. Provided also is a method for disassembling a spring-biased mechanism including a spring capture assembly. | 12-24-2015 |

137315420 | Including sealing feature | 2 |
20090266425 | EXCESS FLOW VALVES - An excess flow valve (EFV) for installation in a service line of natural gas distribution system serving an existing structure. The EFV has a cylindrical housing having a first length and a second length and a through hole therethrough for passage of gas. The EFV | 10-29-2009 |
20140283926 | Foldable, Double-Block and Bleed Plugging Tool - An isolation tool for temporarily isolating a section of pipeline has foldable semi-circular sealing element halves that, when unfolded, combine to form a primary and secondary sealing element. The element halves unfold by rotating an inner bar about an outer bar. A bleed hole permits any fluid which leaks past the primary sealing element and into the annular space between the sealing elements to enter a longitudinal bleed passageway located within the tool itself, thereby eliminating the need for a bleed port or valve to be welded onto the pipeline. The tool, which is pressure balanced, is well adapted for use in applications in which the lateral access opening is significantly smaller in diameter than the pipe diameter. | 09-25-2014 |
