    摘要： The connection consists of a module (2) for connecting a pipe-line, free to swivel around a hollow screw (1) comprising a flap valve which is loaded by a weak return spring (5) to close against its sitting (3a) which constitutes the main passage of fluid flow through the apparatus. The flap valve (3) is integral with a rod (4), the free end of which is guided in the bore (10) of a plug (9), beyond a seal (6). The hollow screw also comprises means for conveying a small flow of fluid tapped from the sitting (3a) in order to fill an installation downstream of the apparatus, after which the flap valve (3) is opened by the effect of pressure. The apparatus is designed in two versions, one admitting pressure to the network via the module (2) and the other via the end of the hollow screw (1). Applications for pneumatic engineering.

    摘要： A device is provided for controlling the initial pressurization of a pneumatic system having a pressure supply line with an inlet end and a tail end and at least one pneumatic actuator in the system. The device includes a pneumatic valve having a first and second inlet port and an outlet port. The valve is movable between a first position in which a first fluid passageway connects the first inlet port to the outlet port, and a second position in which a second fluid passageway connects the second inlet port to the outlet port. A user variable orifice is connected in series between the source of pneumatic pressure and the first inlet while the source is fluidly connected directly to the second inlet. Similarly, the outlet from the valve is connected to the inlet end of the pressure supply line of the pneumatic system. A biasing member urges the valve towards its first position while a pneumatic switch switches the valve to its second position whenever the pressure at the tail end of the pressure supply line exceeds a user selected pressure.

    摘要： For the purpose of providing a valve arrangement for controlling pneumatic drives with protection against a sudden automatic change in the initial switching position without an input signal in the event of a fault in a resetting device of a pilot stage and, for this situation, effective fault identification by purely pneumatic means, said valve arrangement comprises a first and a second working connection (1; 2), which can be connected to a drive, and a first and a second electropneumatically pilot-controlled directional valve, in which valve arrangement one or both directional valves is or are arranged upstream of the working connections (1; 2) for the purpose of influencing and venting said working connections, wherein the pilot stages of both directional valves are of automatically resetting design and the second directional valve is designed for alternately assuming an inoperative position and a switching position and the pilot stage of the first directional valve has an external control connection (8; 8′) which can be influenced by means of the second directional valve in its switching position and can be vented by means of said second directional valve in its inoperative position, wherein the second directional valve has, as a resetting device for the main stage (14), an air spring (19) which can be influenced and can be vented externally by means of the first directional valve, and a change in state between influencing or venting of the air spring (19) after the first directional valve assumes a switching position takes place only depending on the change in the switching state of the first directional valve, and a change in state between influencing or venting at one working connection (1; 2) after previous influencing or venting which took place with the second directional valve assuming the switching position takes place only depending on the second directional valve assuming the inoperative position.

    摘要： A safety valve for use in a compressed air line having a supply valve and a control valve, to prevent inadvertent sudden shifting of the controlled part when the line is exhausted and later repressurized. The safety valve comprises a normally closed piston-operated poppet valve, the piston chamber and outlet port being connected to the supply port through a bypass with an adjustable restriction upstream of the valve member. In one embodiment, the adjustable restriction comprises a replaceable plug threaded in the valve body. In a second version, the adjustable restriction comprises a needle valve mounted in a housing cover.

    摘要： A fluid control valve includes a first flow path and a second flow path that connect a first port and a second port in parallel. The first flow path includes an opening and closing valve mechanism that temporarily opens the first flow path. The second flow path includes a throttle valve mechanism that restrictedly opens the second flow path. The opening and closing valve mechanism includes an opening and closing valve portion including an opening and closing valve seat and an opening and closing valve body, a valve opening force generator, and a delay valve closing mechanism that closes the opening and closing valve body after a delay time has elapsed. The throttle valve mechanism includes a throttle valve portion. The opening area of the opening and closing valve portion is larger than the opening area of the throttle valve portion.
