Abstract
An apparatus and associated method, 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. A movable member and a reservoir of the device are configured such that the movable member is sufficiently movable to increase the volume of the reservoir to remove a sufficient portion of the third fluid bound between the first and second diaphragms from the chamber to cause the first and second diaphragms to be pressed against the first and second walls, respectively.
