Abstract

In an electro-pneumatic signal converter, the piezoelectric bending element is elastically pretensioned against at least three support bearings, of which one can be adjusted to a desired setting. This consists of a sleeve insert, the position of which is fixed relative to the other support bearings after the initial adjustment, for example, by being cemented, and a support pin that can also be moved subsequently in an axial direction relative to the sleeve insert, which can also be simultaneously in the form of a contact pin.
