摘要： A bistable fluid valve is characterized by two valve chambers which are arranged adjacent to one another and are closed off with respect to one another by a partition and each have an inlet opening and an outlet opening situated opposite one another, by an S-shaped elastic strip element which extends through both valve chambers, is articulatedly mounted in the region of the partition and can assume two positions in which it sealingly closes off either one or the other outlet opening, and also by an actuation element which is fastened to the strip element and by means of which the strip element can be switched between the two positions. The fluid valve according to the invention comprises only a single movable component of very low mass, which can thus operate in a fast-reacting manner.

摘要： The invention relates to a diaphragm arrangement which is intended to be fitted to a structural component or fixing ring for the purpose of generating sound, having two piezo crystals which are fitted opposite one another on either side of an electrically conductive diaphragm which can oscillate, wherein the piezo crystals are each fastened to the diaphragm, which has a connection contact, in an electrically conductive and force-transmitting manner, and the piezo crystals are each electrically conductively connected to a contact plate on their opposite side. In this case, each contact plate has at least one contact strip which extends in the direction of the structural component and of which the end in each case has an electrical connection contact. The diaphragm arrangement can be excited by electrical voltages which can be applied to the three connection contacts. This produces a secure contact-connection during operation and the contact plates act as heat-conducting plates for dissipating heat from the piezo crystals.
