Abstract
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.
