Piezoelectrically operated valve has sealing element on piezoelectric flexural transducer with end fixed in valve housing, end movably guided in longitudinal direction in housing groove

摘要

The valve has at least one valve channel closed by a sealing element (14,16) on a piezoelectric flexural transducer (7,8) with two ends. The transducer is fixed in the valve housing (2) by the first end; the second end is movably guided in the longitudinal direction in a housing groove (11) on the side of the housing opposite the first end. The end fixed in the housing is connected to an electrical voltage source (U1,U2) to actuate the valve.
