摘要

The valve has a two-part housing (1), closing bodies (4, 6) present in the housing, and a valve seat provided for the bodies. The bodies are pressed at the valve seat for closing the valve using a lever. An arm of a double-armed lever (2) is pressed against the bodies and another arm of the lever is movable with a piezo-actuator (3). The lever is articulately held with a support-forming membrane (2a) in the housing. The membrane is formed as a single piece with the lever. The membrane partitions a drive-sided area in the housing from a closing body-sided area.
