摘要： An aircraft gas transport system (110) includes a high pressure gas supply line (115) having a supply valve (120). The gas transport system also includes an equilibrium gas line (150) joined at junctions with the high pressure gas supply line upstream and downstream from the supply valve, and in flow communication with the high pressure gas supply line. The equilibrium gas line has an equilibrium valve (140) and a flow restrictor (135). The equilibrium valve has an exit orifice (173), and the flow restrictor is offset from the exit orifice of the equilibrium valve.
A method for pressurizing a gas transport system (110) after a flow of gas through the gas transport system has been prevented (400) comprises: opening (410) an equilibrium valve (140) while maintaining a supply valve (120) closed to allow a flow of gas (GFA) through a flow restrictor (135) that controls a rate of change of a pressure downstream of the equilibrium valve; determining (420) that the pressure downstream of the equilibrium valve or supply valve is stabilized; and opening (430) the supply valve to provide a flow of gas (GFB) through the supply valve at an operating pressure.

摘要： A fluid flow control device includes a valve body, a valve seat disposed within the valve body, and a valve cage coupled to the valve seat within the valve body. The fluid flow control device also includes a gland defined by the valve body, the valve seat, and the valve cage. The valve body has a first thermal expansion coefficient and the valve seat and/or the valve cage have a second thermal expansion coefficient different from the first thermal expansion coefficient. The fluid flow control device further includes a sealing assembly disposed within the fluid flow control device to provide a seal between the valve body and the valve cage. The sealing assembly exploits differential thermal expansion between the valve body and the valve cage in a direction parallel to the longitudinal axis and in a direction transverse to the longitudinal axis to improve the seal.

摘要： An expansion valve having an inlet opening, at least one outlet opening and first and second valve parts. The inlet opening is adapted to receive fluid medium in a liquid state. The outlet opening(s) is/are adapted to deliver fluid medium in an at least partly gaseous state to a flow path. The valve parts are arranged movable relative to each other such that the mutual position of the valve parts determines a fluid flow between the inlet opening and the outlet opening(s). During normal operation, a resulting force acts upon the first valve part and/or the second valve part to press the first and second valve parts towards each other. The expansion valve having ability for reducing the resulting force acting upon the valve part(s). Thereby the valve parts can easier be moved relative to each other, and the force required in order to operate the valve is thereby reduced.

摘要： Disclosed is a solenoid-operated valve which hardly brings a plunger into a lock and is capable of improving its responsively. In the solenoid-operated valve, the plunger (16) slidably guided in an inner bore (11a) formed in a yoke (12) and a core (13) aligned axially is moved by energizing an electromagnetic coil (17), and a spool (26) in a valve section is moved through a rod portion (26a) which protrudes from an end of the plunger (16) to pass through a center hole of the core. An electromagnetic section fluid chamber (B) defined by a forward end surface of the plunger and the inner bore (13a) of the core communicates with an intermediate fluid (D) chamber defined between the core (13) and a valve sleeve (21), through a clearance (C) between the center (13a) hole and rod portion (26a). The spool (26) is provided at one end thereof with a land (27a) portion whose end surface defines a part of the intermediate (D) fluid chamber. The diameter (d1) of the land portion is chosen to be the same as the diameter (d2) of the plunger, so that the sum in volume of the electromagnetic section (B) fluid chamber and the intermediate (B) fluid chamber can be kept invariable regardless of movement of the plunger (16). A supply/drain (18) passage is further provided to permit the oil around the solenoid-operated valve to be charged into the rear (A) end fluid chamber or discharged therefrom upon movement of the plunger (16).

摘要： An hydraulic valve has two outlets 43 and 44 and is switchable so that fluid can only be supplied to one outlet at a time. A spool 47 with two seals 48 and 49 is slidable in a housing 45 under the action of two solenoids 61 and 62 and is urged to a central position by two springs 56 and 57 where the seals block passage to both outlets 43 and 44. When the spool 47 is moved in one direction it allows flow to one outlet and also allows flow via a bypass channel 67, 69 to an opposite side of the spool counteracting the force applied by the solenoid so that the force applied to an outlet can be controlled gradually.
