摘要： An integrated pressure regulator is provided with three stages configured to reduce an extreme tank pressure down to a typical working pressure. The regulator is configured to supply a steady working pressure until the tank pressure is reduced to little more than the working pressure itself. Stages of the pressure regulator are integrated into a body and arranged to minimize regulator mass and volume. A thermally-triggered pressure relief device may be included with a triggering time adapted to enhance the safety of smaller cylinders that may be used, e.g., in aerial applications.

摘要： This pressure-reducing valve includes: a casing in which a valve passage is formed; a valve body that is movably housed in the casing and changes a position thereof according to a secondary pressure to adjust an opening degree of the valve passage; and a biasing member that biases the valve body against the secondary pressure in an opening direction in which the valve passage opens. The biasing member is a spring in the form of a plate and extends laterally from the valve body.

摘要： An over-pressure vent (OPV) system is provided for a fuel tank of an aircraft. The OPV system includes an OPV valve configured to be coupled in fluid communication with a supply line of a nitrogen enriched air distribution system (NEADS) such that the OPV valve is configured to vent pressure from the supply line. The OPV valve is configured to be coupled in fluid communication with the supply line upstream from an outlet of the supply line from which the NEADS delivers nitrogen enriched gas to the fuel tank. The OPV valve is configured to sense a pressure within the supply line upstream from the outlet of the supply line.

摘要： A pilot assembly is configured for use with various types of flow controls. These configurations include a manifold with an internal flow network that connects pilot valves and an adjustable orifice. The pilot valves may have a fixed and variable differential pressure. In one implementation, the manifold comprises a pair of separable blocks, one each that includes part of the internal flow network. This construction also permits the manifold to expand with, for example, and additional block for an additional pilot valve. This feature configures the manifold for use in working monitor systems or those systems that deploy multi-stage pressure regulation.

A coupling installation (64) is provided having coupling parts (66, 68) arranged on both sides in the direction of the lifting movement of the actuating membrane member (20), which coupling parts are adapted to a connection (70) an the valve shaft (18) such that the connection of the valve shaft (18) with the actuating membrane member (20) is carried out by a one-sided mounting, wherein the valve shaft (18) is adapted to be connected to each of the coupling parts (66, 68) of the coupling installation (64). On the actuating device (2) a distance measuring system (48) is arranged, which comprises a connection (72) which is adapted to be connected to each of the coupling parts (66, 68) of the coupling installation (64) by means of a one-sided mounting, wherein the coupling parts (66, 68) are constructed in analogy to the corresponding connections (70, 72) for selectively fastening of the valve shaft (18) or the distance measuring system (48) to the coupling installation (64).

摘要： Provided is a valve structure capable of suppressing the vibration of a valve body. The valve structure includes a valve body and a valve seat. The valve seat has a flow path of a fluid. The flow path opens and closes. A groove surrounding a central axis of the flow path is formed in a flow path wall surface downstream of a contact section between the valve body and the valve seat.

摘要： A pressure reducing valve has a seal member, which is mounted on a side wall of a piston. The seal member is arranged between a first ring and a second ring. Consequently, depending on the direction of displacement of the piston, the first ring or the second ring is positioned on one of a displacement direction upstream side or a displacement direction downstream side of the seal member. The first ring and the second ring are made of a resin material, for example a polytetrafluoroethylene resin or a polyetheretherketone resin, having lower coefficient of friction compared with that of the seal member.

摘要： The invention relates to a device for regulating the flow rate and/or pressure of a fluid, such as valve for a pressure gas cylinder, comprising a reducing valve including a first plug designed to be moved in the normal flow direction of the fluid during closure. The reducing valve also comprises a plunger to which the plug is coupled. The face of the plunger that is oriented towards the first plug defines a regulation chamber together with the body. The aforementioned face also comprises a seal that engages with a corresponding surface of the body such as to form a second plug for maintaining residual pressure. The regulation device also comprises a means for preloading and releasing a spring acting on the opposite face of the plunger.
