Valve for liq. flow control contains valve chamber connectable to high pressure region in dependence on position of valve stop member, energizable by piezoelectric actor assembly,

摘要

The valve (1) comprises valve chamber (14) connectable to high pressure region (2) in dependence on valve stop member (11), energizable by piezoelectric actuator assembly, and a link (15) to low pressure region (16).The throttling to link of valve chamber to low pressure region variably adjusts pressure rise in valve chamber, when connection from valve chamber to a high pressure region is open. A throttle (17) with variable cross-section is integrated in the link.
