摘要： 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.

摘要： A fluid flow control device such as a volume booster has an inlet, an outlet and an exhaust port all for an operating fluid. A pilot inlet receives a pilot pressure signal which operates a valve stem actuator via a piston. The valve stem is operable to open a supply valve between the inlet and outlet and, separately and independently, to open an exhaust valve disposed between the outlet and the exhaust. In a further position both the valves are closed. Movement of the stem in a reciprocal manner by the piston causes a respective annular shoulder to engage a respective valve and lift it off a valve seat against the force of a biasing spring. A first fluid leak path is provided between the valve stem and the supply valve for allowing fluid to leak through the supply valve chamber when the supply valve is open and a second fluid leak path is defined by the exhaust valve for allowing fluid to leak through the exhaust valve chamber. The leak paths provide for a force balancing arrangement that allows the valve stem to move easily. A quick exhaust feature allows exhaust flow through the device instead of using a separate component. A regulated flow is provided to the actuator. The size of the exhaust port may be modulated by pilot control pressure.

摘要： A flow control device is provided comprising:a housing (19) including a first chamber (21) communicated with an inlet port (11) and a second chamber (22) communicated with an outlet port (12); a cylindrical portion (25), which extends in the second chamber, for communicating the first chamber with the second chamber; a valve seat (61) provided at a forward end portion (25a) of the cylindrical portion; and a valve body (32) for opening and closing the valve seat, wherein at least one of the valve seat and the valve body is made of a material, the heat deformation of which is smaller than that of material composing the cylindrical portion. Due to the foregoing, it is possible to stably adjust the flow rate of a fluid of a high temperature and pressure. A pressure chamber (29), which is communicated with the second chamber and provided with a pressure port (18), may be arranged in the housing. A first and second flexible separation means (41, 51), which are connected to each other, for separating the second chamber and the pressure chamber from each other may be provided and a bed (75) arranged between the first and the second flexible separation means may be also provided. A reinforcement member (90) may be embedded in the cylindrical portion (25).

摘要： The dual actuator valve of the present invention deploys both the primary and secondary actuator elements in a single, common control chamber. Therefore, the present invention provides a dual actuator valve having dimensions that are the same as, or similar to, the dimensions of a single actuator control valve. It will be appreciated that the actuator elements may be of diaphragm type or piston type actuator elements. The primary actuator element is mechanically linked to the valve plug and regulates the flow though the valve, while the secondary actuator element remains in a fully open position. Should the primary actuator element fail to operate the valve due, for example, to diaphragm rupture, failure of the primary control system, or any other reason, the secondary control system activates the secondary actuator element, which then effects movement of the primary actuator element thereby resuming flow regulation or closure of the valve as necessary.
摘要翻译：本发明的双致动器阀将主致动器元件和辅助致动器元件都布置在单个公共控制室中。因此，本发明提供了具有与单个致动器控制阀的尺寸相同或类似的尺寸的双致动器阀。应当理解，致动器元件可以是隔膜式或活塞式致动器元件。主致动器元件机械地连接到阀塞并调节通过阀的流量，而辅助致动器元件保持在完全打开位置。如果主致动器元件由于例如隔膜破裂，主控制系统的故障或任何其他原因而不能操作阀，则次级控制系统激活辅助致动器元件，其然后实现主致动器元件从而根据需要恢复阀的流动调节或关闭。

摘要： An actuator assembly for operating a setting member includes an actuator body undergoing a dimensional change upon applying electrical energy thereto; a preliminary pressure chamber for accommodating liquid; a diaphragm sealing the preliminary pressure chamber and being displaceable by the actuator body; a valve member carried by the diaphragm; a transfer chamber for accommodating liquid; and a displaceable plate body disposed in the preliminary pressure chamber and sealingly bounding the transfer chamber. The diaphragm, as it is moved by the actuator body, displaces the plate body. A displaceable piston body sealingly bounds the transfer chamber and has a surface which is smaller than the surface of the plate body, whereby the plate body--with the intermediary of the liquid--displaces the piston body to a greater extent than the displacement of the plate body. The piston body, as it moves, displaces the setting member. A valve opening provided in the plate body is closed or opened by the valve member carried by the diaphragm. In the open position of the valve member, the valve opening establishes a hydraulic communication between the preliminary pressure chamber and the transfer chamber.
