| description | PCT No. PCT/DE93/00493 Sec. 371 Date Dec. 16, 1994 Sec. 102(e) Date Dec. 16, 1994 PCT Filed Jun. 8, 1993 PCT Pub. No. WO94/00696 PCT Pub. Date Jan. 6, 1994The microvalve according to the invention is composed in a layered manner of at least one bottom part (11), one middle part (12) and one top part (13). The sealing ring (31) (closure member), the valve plate (29) (pressure-compensating surface) and the membrane (26) are integrated in the middle part (12), this integral component being manufactured by a plastic moulding process. The actuation of the valve takes place using an electrical operating apparatus, for example by an electrostatic drive, an electromagnetic or a piezoelectric drive. In particular in the case of the electrostatic drive, two electrodes (17, 22) are applied in a layered manner to the middle part (12) or the bottom part (11). The bottom part, middle part and top part are joined together and connected, for example bonded or welded, permanently to one another. |
