Abstract
The invention relates to a microvalve (1) having a valve chamber (6) and a disk-shaped valve body (valve disk (4), which is connected via sprung elements (5) to the edge of the valve chamber (6) and controlled in two movable and different positions in which it closes or releases a valve opening (7) at the base of the valve chamber (6). In order to obtain especially high operating forces for the valve disk (4), the invention proposes to form the valve disk as a magnet armature (4, 9) for an electric coil (10) located in the area of the valve opening (7). The effect of the electric coil (10) can still be increased by a permanent magnet (12).
