Abstract: The operating unit comprises an actuator, which mechanically excites an operating element. The actuator comprises a support strip made of a resilient material. Piezo elements, which are connected to the support strip in a shear-resistant manner, are located on both outer surfaces of the support strip. As a result of the alternate arrangement of the piezo elements, the support strip assumes an undulating form when moving out of its inactivated state. One side of the support strip is mechanically connected to the operating element and the other side is mechanically connected to a counterbalance. The support strip itself is mechanically fixed in the housing. In its inactivated state, the operating element and the counterbalance are at a different distance from one another than in the undulating activated state, wherein they move in opposite directions and thus lead to a compensation of dynamic forces acting on the housing.

Abstract: A device (1) for lowering flow noises has opposed first and second connection pieces (2, 3), and outer and inner sleeves (4, 5) between the connection pieces. A radial collar (6) is between the sleeves (4, 5) and forms separated volume chambers. Openings (11) in the inner sleeve (5) connect the volume chambers to a line space (13) enclosed by the inner sleeve (5). A sealing ring (15) at the free end (14) of the collar (6) defines a ring cap with a lateral surface (21) that reaches over the collar (6) and seals against the sleeve (4, 5) adjacent the free end (14) of the collar (6) and that has a surface (23, 26) that seals against either an end face (25) of the collar (6) or a side surface (28) of the collar (6) extending parallel to the radial collar (6).
