Patent number: 6811136Abstract: 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.Type: GrantFiled: May 19, 2003Date of Patent: November 2, 2004Assignee: Festo AG & Co.Inventors: Wolfgang Eberhardt, Heinz Kück, Carsten Pein, Frank Pöhlau, Andreas Schmid, Stefan Klump, Michael Riedel, Jürgen Sestak, Udo Töpfer, Hubert Krämer, Martin Maichl, Markus Hoffman, Gebhard Munz, Michael Weinmann
