    • An apparatus, for controlling signal passage, includes a first passageway for a first fluid, a second passageway for a second fluid, and an interposed chamber. A first, movable diaphragm at a first chamber junction and a second, movable diaphragm at a second chamber junction, with a third fluid bound there between and interposed between the first and second passageways. A device varies a volume of the third fluid bound between the diaphragms and thus moves the diaphragms. The diaphragms each have at least one position that permits passage of a pressure signal between the first fluid in the first passageway and the second fluid in the second passageway through the third fluid bound between the diaphragms. The diaphragms each have at least one position that prohibits passage of a pressure signal.
    • 用于控制信号通过的设备和相关方法包括用于第一流体的第一通道,用于第二流体的第二通道以及介入室。 第一腔室接合处的第一可移动隔膜和第二腔室接合处的第二可移动隔膜,第三流体束缚在第一和第二通道之间并介于第一和第二通道之间。 装置改变了隔膜之间的第三流体的体积并因此移动了隔膜。 该装置的可移动构件和储存器被构造成使得可移动构件可充分地移动以增加储存器的容积,以将第一和第二隔膜之间的第三流体的足够部分从腔室移除以引起第一和第二隔膜 第二隔膜分别被压靠在第一和第二壁上。
