A flexural actuator is fitted with an actuator means, the flexural actuator being fitted at its functional section with a sensor means for determination of the longitudinal stretch. This sensor means is placed at a position, and/or is placed in the longitudinal direction symmetrically on either side of such position, at which there is a constant longitudinal stretch independent from the setting force when the functional section is thrusting against a resistance.

Flexural actuator and an actuator means fitted with same

A piezoelectric valve whose housing defines a valve chamber wherein at least one piezoelectric flexural transducer is located. The piezoelectric flexural transducer possesses a contact face, which faces a first outer wall of the valve housing. This first outer wall is in the form of a wiring support which possesses a support body consisting of plastic material, which at the outer side opposite to the valve chamber bears a wiring arrangement. The wiring arrangement is in electrical contact by way of a via extending through a cutout in the support body with the piezoelectric flexural transducer, since the via consists of an electrically conductive elastic plug, against which the at least one contact face is thrust at the inner face of the support body.

Piezoelectric valve

A piezoelectric flexural transducer having an elongated support body ( ) which on at least one longitudinal side is provided with a piezoelectric unit ( ). The piezoelectric unit ( ) has one or more piezoelectric material layers ( ) and electrodes ( and ) associated with same. Furthermore, the piezoelectric unit ( ) includes an electrically insulating coating surrounding the body ( ) right round it, the section ( ) of the coatings lying between the piezoelectric body ( ) and the support body ( ) being provided with one or more electrically conductive vias ( and ). The latter provide the necessary electrical connection between the electrodes ( and ) and the support body ( ).

Piezoelectric flexural transducer and use thereof

A piezoelectric flexural transducer having an elongated support body ( ), that on at least one longitudinal side is provided with a piezoelectric multi-layer body ( ). In the interior of the support body ( ) and/or between the support body ( ) and the piezoelectric multi-layer body ( ) and/or between neighboring piezoelectric material layers of the piezoelectric multi-layer body ( ) at least one component ( and ) of an electronic ( ) and/or sensor ( ) system is accommodated employed for the operation of the piezoelectric flexural transducer.
