137537000 | Spring under tension | 8 |
20090320940 | CONNECTOR CLAMP WITH PRESSURE VALVE - A connecting device for a hydraulic system is provided. In an embodiment, the device includes a valve provided in a passage channel that can be configured to switch flow based on a pressure differential between passage channel pressure and ambient pressure. In an embodiment, the connecting device may include a valve housing provided in the form of a bolt, and the valve housing may be configured for connection to an assembly unit. | 12-31-2009 |
20130213499 | NON-RETURN VALVE FOR A FLUID PUMP - A non-return valve for a fluid pump, in particular of a safety brake system of a motor vehicle, includes a through-flow opening configured to be closed by a valve element. The valve element is configured to be displaced against the spring force of a valve spring made of coiled round wire to expose the through-flow opening. The round wire is coiled in one plane and is arranged with respect to the valve element such that the plane extends at least substantially perpendicularly to the displacement direction of the valve element. | 08-22-2013 |
20140020774 | CHECK VALVE HAVING AN OPTIMIZED CLOSING ELEMENT - A check valve ( | 01-23-2014 |
20140130908 | PRESSURE RELIEF VALVE AND SECONDARY SPRING FORCE CONTAINMENT ASSEMBLY - A valve having secondary spring force containment includes a valve body featuring an opening with a valve closure member sized to close the opening. A stem has a first end connected to the valve closure member. A proximal spring seat is positioned adjacent to the valve body, A distal spring seat is mounted on the second end of the stem. A spring is positioned between the proximal and distal spring seats so that the valve closure member is urged into a position where the valve body opening is closed. A hollow rod is attached between the proximal and distal spring seats to provide secondary spring force containment with the stem passing through the hollow rod. | 05-15-2014 |
20140158230 | LIQUID DRIP PREVENTION VALVE - In a liquid drip prevention valve, an input port is formed in the upper face of a flow passage block, and an output port is formed in the lower face, which opposes the upper face of the flow passage block. In addition, a valve chamber is formed on a side face of the flow passage block, and an air block abuts the side face. Furthermore, a diaphragm valve makes contact with a valve seat when pressure is applied with respect to a back side chamber of the diaphragm valve and separates from the valve seat when the back side chamber is brought to negative pressure, thus forming the liquid drip prevention valve. | 06-12-2014 |
20140216575 | CHECK VALVE - To provide a check valve which can be used even under a high temperature condition by overcoming a drawback “valve element sticking to sealing member” associated with high temperature use while enhancing heat resistance. An opening of a fluid path formed in a first body is brought into a closed state by bringing a valve element biased by a biasing member into contact with a sealing member. The sealing member is formed of a post-cured perfluoro elastomer packing. An annular sealing portion which is brought into line contact with the sealing member is formed on the valve element. | 08-07-2014 |
