摘要： Servo-valve that controls fluid discharged from a nozzle discharge port by displacing the nozzle, and that drives an actuator. The servo-valve includes a receiver having an inflow surface provided with a first inflow port, and a second inflow port into which fluid discharged from the discharge port flows. The nozzle includes a force generation portion having an end surface provided with the discharge port, and an outer circumferential surface formed on the periphery of the end surface. Displacing the nozzle from neutral position toward the first inflow port blows the fluid inside the second inflow port out toward the nozzle. The force generation portion collides with the fluid blown out from the second inflow port, causing assisting force in a direction matching the direction of nozzle displacement toward the first inflow port. The nozzle easily moves by the assisting force generated in the force generation portion, improving response speed.

摘要： Servo-valve that drives an actuator by using a fluid. The servo-valve includes a nozzle having a discharge edge forming an outline of a discharge port from which the fluid is discharged and a tapered inner wall growing narrower toward the discharge edge, and a receiver that is provided with a flow path into which the fluid discharged from the discharge port flows. The nozzle is displaced in a direction different from the fluid discharge direction. The flow path extension direction is inclined with respect to a direction orthogonal to an inflow surface facing the nozzle by an angle α. A taper angle determined by the tapered inner wall is larger than twice the angle α. With such a configuration, the component of flow force exerted from the fluid on the tapered inner wall decreases. Since the nozzle can be quickly displaced, response speed of the actuator is improved.

摘要： In a pneumatic actuator for setting a control armature, a first working chamber and a second working chamber are pneumatically separated from each other by a moveable dividing wall to which the control armature is coupled in a force-transmitting manner. The dividing wall, in case of a pressure difference between the working chambers, is displaced in a first control direction. A positioner is adapted to output at least one pneumatic control signal to the first working chamber. The first and the second working chambers are pneumatically connected to each other via a pneumatic short-circuit duct with a balancing valve disposed in the short-circuit duct for at least one of closing or opening the short-circuit duct. The balancing valve is driveable by the positioner such that in case of a certain operating condition, the balancing valve pneumatically short-circuits the first and the second working chamber for achieving a pressure balance between the chambers.

摘要： To provide a four-way solenoid valve having a three-way solenoid valve of which non-concentricity between a valve element and a valve hole is small, if any. A core of a three-way solenoid is integrally formed with a refrigerant passage extending axially therethrough, an annular projection forming a valve seat, and a guide for guiding reciprocating motion of a needle forming a valve element. A plug closing a cylinder of a body to define the pressure control chamber is also integrally formed with a valve seat and a guide for guiding reciprocating motion of a needle forming a valve element associated with the valve seat. This causes the needles to be seated on the valve seats associated therewith in respective states guided by the guides substantially concentric with the valve holes, which makes it possible to impart sufficient sealing properties to the valve portions when each valve is closed.

摘要： In a four-way directional control valve of simplified construction and reduced manufacturing costs, first and second hollow cylindrical valve elements are arranged coaxially. Adjacent to opposite ends of the valve elements, first and second valve seats and first and second valve closure elements are provided. First and second pressure-regulating chambers are arranged between separator walls of the valve elements and first and second partition walls associated to the first and second valve seats. A pilot valve can be switched between switching positions for introducing high-pressure fluid originating from a first pipe into the first or second pressure-regulating chamber via a common high-pressure passage, a high pressure introducing hole and two pilot holes, respectively, associated to the pressure-regulating chambers. The control valve can be switched into a state where the first pipe communicates with the fourth and the second pipe communicates with the third pipe and to another state where the first pipe communicates with the third pipe and the second pipe communicates with the fourth pipe.

摘要： A pilot-controlled solenoid valve apparatus includes a valve housing having an entrance chamber, an exit chamber, and a discharge chamber formed therein. An inlet valve controls fluid pressure flow from the entrance chamber to the exit chamber while an outlet valve controls fluid pressure flow from an exit chamber to the discharge chamber which exhausts to atmosphere. The inlet and outlet valves each include respective membrane diaphragms which have control chambers disposed on one side; which control chambers are pressurized by means of respective inlet and outlet control valves. Disposed on each of the membrane diaphragms are annular symmetric bodies which each have a longitudinal bore formed therein to allow communication between the respective control chambers and the exit and discharge chambers when the respective control valves are opened. An inlet and an outlet solenoid valve arrangement controls operation of the respective inlet and outlet control valves. A valve anchor associated with each of the solenoid valves has formed on one side thereof, a pilot valve seat. Formed on the opposite side of the valve anchor is a control valve body, which by being formed integrally with the pilot valve body, allows simultaneous operation of the solenoid and control valve portions of the solenoid valve apparatus. A bias spring engages the valve anchor near the control valve body to urge the anchor and thus, the control valve body toward the annular symmetric body on which is formed the control valve seat, when the solenoid valve arrangement is not energized.

摘要： A solenoid valve unit for the control of the supply of compressed air to an air driven load and controlling the letting off of such air from the load has a valve housing with a pressure port, a power air port, a let off port for the valve space and a further let off port for the load driven by compressed air. The further pressure let off port is opened up and shut off by a valve plate or thimble that is only moved by pressure. This design makes possible a compact form of the valve so that the pressure port, the power air port and the further pressure let off port are placed on only two housing faces.
