Pivoting valve device, especially an amplifier

摘要

A valve means (1) containing a switching element in the form of a switching rocker member (13). The rocking arms (18 and 18') placed on either side of the pivotal portion (15) of the switching rocker member (13) are respectively engaged by a respective actuating diaphragm (35 and 35') and adjacent thereto there is a closure portion (27 and 27') associated with a duct opening (24 and 25). A valve means designed in this manner renders possible a particularly flat, planar structure with compact dimensions and a small dead volume.
