Bending transducer valve, has transducer arrangement comprising lamellar piezoelectric bending transducers, whose front end regions are individually movable by electrical activation in order to impact positions on same valve member

摘要

The valve has a bending transducer arrangement (37) extending in a valve housing (5) and supported at its rear end region (42) relative to the housing. A valve member has a front end region moved by electrical activation. The actuating force is exerted on the member to operate the member for controlling channel openings. The arrangement has lamellar piezoelectric bending transducers (43, 44) extending in a side-to-side manner. Front end regions (46) of the transducers are individually movable by electrical activation in order to impact the positions on the same valve member.
