摘要： A valve provided for the blocking or controlled establishment of a volume flow of a working fluid in a flow path of a technical device that transmits and/or stores energy, in particular in a control device for a hydraulic drive, an associated method of manufacture of the valve, and an apparatus with the valve. The valve includes first, second, and third valve openings, a moveable shut-off body moveable between an open-position and a close-position, a guide which guides the shut-off body between the open-position and the close position, and a retainer which exerts a retaining force on the shut-off body in the close-position. The guide has three guide parts. The first and third guide parts enclose the shut-off body and the second guide part includes a plurality of pins in a parallel orientation to the direction of movement of the shut-off body.

摘要： A pressure relief valve 1 having small dimensions and generating a high flow rate comprises an annular channel 15 between the pressure medium inlet 7 and the pressure medium outlet 8, the channel acting on a sealing cone 17 made of a special plastic material at the upper end of the closing unit 17 in case of pressure peaks such that the same is lifted out of the sealing seat 12 against the force of the valve spring 6. An embodiment is also possible in which the corresponding sealing rings 76, 80 must be passed over. The inner bore 9 of the pressure relief valve 1 has a stepped wall 21, so that a differential pressure relieving the valve spring 6 is generated.

摘要： A self-regulated valve assembly contains a valve body which, in the lower part, has an input section for a connection to a tank intended to contain a fluid under pressure and, in the upper part, an output for connection to a pipe system. A piston is movable in the valve body along a first axis between an open position, enabling the fluid to communicate between the input section and the output, and a closed position. A spring type module is coupled to the piston and to the valve body and interacts dynamically with the piston at least after an actuation of the valve and during the entire cycle of self-regulation of the valve, imposing a positioning of the piston between its open and closed position. The spring type module is positioned beneath the lower sealing section of the piston and the dimensions of the valve assembly can be considerably reduced.

摘要： A passive hydraulically actuated non-electric shutdown pressure relief valve relieves pressure in the high pressure volume of a low static leak common rail fuel system after shutdown. When the common rail fuel system is in operation, a transfer pump provides medium pressure to hold the shutdown pressure relief valve closed. At shutdown, the residual medium pressure downstream from the transfer pump decays back to tank, and the residual high pressure trapped in the common rail and fuel injectors pushes open the shutdown pressure relief valve to release the high pressure after back to tank.

摘要： Valve stem and valve plug apparatus for use with fluid regulators are described herein. An example fluid regulator includes a flow control member having a body that includes a longitudinal bore between a first end and a second end and a valve stem is disposed in the bore of the flow control member. A connector slidably couples the valve stem and the flow control member such that the connector moves away from the flow control member to relieve the flow control member of a loading force imparted by a loading element of the fluid regulator when the flow control member sealingly engages a valve seat of the fluid regulator.
