Piezoelectric actuator e.g. for IC engine, has plate-shaped bearer with at least two separate piezo stacks on both upper and lower sides of bearer and drive output near bearer's longitudinal central axis
The device has a plate-shaped bearer (2) with at least two separate piezo stacks (3,4;5,6) on both the upper and lower sides of the bearer and a drive output near the bearer's longitudinal central axis between the stacks on the upper and lower sides of the bearer and bearings on the end of the bearer. The drive output takes place via a valve closure element of a valve body that is fixed to the bearer.
