    • A gas-blast load-break switch comprises a pressure storage chamber for storing pressure of arc-extinguishing gas with arc energy generated by the disconnection between contacts, and a suction chamber including a piston which is moved in connection with the cut-off movement of the movable contact. A gas flowing device is provided such that the pressure raised by the arc energy is stored in the pressure storage chamber before communicating the pressure storage chamber and the suction chamber and a gas chamber formed on the opposite side of the piston from the suction chamber. The volume of the gas chamber is greater than that of the pressure storage chamber and the suction chamber, and the distance of piston movement in the suction chamber is longer than the contact length when the movable contact is thrown into the fixed contact.

    • A pilot valve device adapted to be brought to an open position in response to a mechanical signal so as to cause a compressed fluid to actuate an operating valve. The pilot valve device comprises a main valve located in a pilot valve chamber, and a daughter valve located in a daughter valve chamber formed in the main valve. When a mechanical signal is applied to the daughter valve and brings the same to an open position, a compressed fluid contained in the pilot valve chamber is introduced into a main valve actuating chamber, with the result that the main valve is brought to an open position to permit the compressed fluid to flow into an operating valve actuating chamber.
    • 一种先导阀装置,其适于响应于机械信号而进入打开位置,以便使压缩流体致动操作阀。 先导阀装置包括位于先导阀室中的主阀和位于主阀中形成的子阀室中的子阀。 当机械信号被施加到子阀并将其引到打开位置时,包含在先导阀室中的压缩流体被引入到主阀致动室中,结果主阀处于打开位置 以允许压缩流体流入操作阀致动室。
