Publication number: 20090308459Abstract: Embodiments of valves permit liquids such as water to flow therethrough at a relatively high flow rate when the temperature of the water is below a predetermined level. The valves reduce the flow rate when the temperature of the water is at or above the predetermined level. The valves can thus facilitate purging of cold water from the hot-water supply piping upstream of the valves at a relatively fast rate, while reducing the flow rate of the water once the water reaching the valves has warmed to a comfortable level.Type: ApplicationFiled: May 13, 2009Publication date: December 17, 2009Inventor: Lloyd A. Gross

Publication number: 20090308460Abstract: A rocker type diaphragm valve is disclosed. The diaphragm (428) in the diaphragm valve is asymmetric and the stroke of the diaphragm is offset from the center of the diaphragm. The two sealing surfaces (318, 320) that the diaphragm acts against form two planes that make an angle with respect to ones another. The diaphragm (428) may be fabricated in only one piece. The diaphragm (428) may also be made from a resilient material and shaped in such a way as to create a spring force holding the diaphragm into a default position in the valve.Type: ApplicationFiled: March 15, 2006Publication date: December 17, 2009Applicant: Norgren, GmbhInventor: Andreas Tschurtz

Publication number: 20090308461Abstract: A pilot valve assembly for regulating the output of a first pressure source relative to a second pressure source, a fluid system equipped with the valve assembly, and a method of operating the valve assembly. The valve assembly includes a valve body with inlet and outlet ports and first and second sensing ports. The first and second sensing ports are adapted to sense, respectively, the fluid pressures of the first and second pressure sources. The inlet port is adapted for fluidically connecting to the first pressure source. The valve assembly defines a flow path between the inlet and outlet ports, and has components for allowing fluid flow from the inlet port, through the flow path, and to the outlet port only if the fluid pressure of the first pressure source exceeds the fluid pressure of the second pressure source by a differential by the flow-allowing components.Type: ApplicationFiled: June 15, 2009Publication date: December 17, 2009Applicant: VANAIR MANUFACTURING, INC.Inventor: Jeff Rohl

Publication number: 20090308462Abstract: A pressure relief device (100) for an inflatable tire comprises a body (102) having a chamber (116) therein and pressure relief mechanism for releasing air when the air pressure in the chamber exceeds a first predetermined pressure level. A conduit (108; 208) inter-connects an air inlet (110; 210) with an air outlet (112; 212). The conduit (108; 208) is provided in a pin (104; 204) arranged to slide axially in a passageway (106) in the body, the pin (104; 204) extending from the air inlet (110; 210) to the air outlet (112; 212) and being slidable between a first position in which it cannot release a stem of the tire, and a second position, in which it can release the stem.Type: ApplicationFiled: May 24, 2007Publication date: December 17, 2009Inventors: Søren Badstue, Amir Shahar

Publication number: 20090308463Abstract: Embodiments of the present invention address deficiencies of the art in respect to bottle traps and provide a bottle trap with an integral gas seal. In an embodiment of the invention, a bottle trap can include a body with both an inlet at a top portion of the body adapted to receive a tailpiece from a sink, and an outlet at a side portion of the body adapted to receive a horizontal drain pipe. The bottle trap further can include an integral metallic gas seal disposed within the body and defining two chambers of the body. The integral metallic gas seal can include a metallic wall being rigidly and non-removably coupled to an interior portion of the body at one end of the metallic wall and having an unattached distal end opposite to the top portion of the interior wall so as to permit passage of fluid from one of the chambers to another of the chambers. Optionally, the unattached distal end of the metallic wall can include a rounded tip.Type: ApplicationFiled: May 15, 2009Publication date: December 17, 2009Inventors: MICHAEL David BACON, Juan Manual Plasencia, Ariel Temprana, Yunus Topcan

Publication number: 20090308464Abstract: Disclosed herein is a device for draining a screw-on fluid filter which comprises a hollow body member movably engaged with a puncturing member. The hollow body member is dimensioned and arranged to at least partially engage a threaded attachment portion of the screw-on fluid filter. The puncturing member comprises a shaft having a puncture end movable within a conduit formed within the hollow body member wherein the puncturing member may be engaged with an inner side of a fluid filter to produce a puncture hole from inside out of the fluid filter, to produce a puncture hole from which fluid in the fluid filter may drain. A method of using the device is also disclosed.Type: ApplicationFiled: January 30, 2009Publication date: December 17, 2009Inventor: MATTHEW SIMON CESARZ
