PCT No. PCT/EP96/03920 Sec. 371 Date May 7, 1997 Sec. 102(e) Date May 7, 1997 PCT Filed Sep. 6, 1996 PCT Pub. No. WO97/09555 PCT Pub. Date Mar. 13, 1997A valve having a housing (1) and at least one sealing seat (2, 3) formed therein and one piezoelectric lamina (6) self-supportingly mounted at its first end on the housing (1) and with its second end closing or opening the sealing seat (2, 3) depending on the control voltage supplied to the lamina (6). The first end of the lamina (6) is embedded in a sealing compound (7) which, in turn is at least partially incorporated in the housing (1). The lamina (6) is thereby rigidly connected to the housing (1). While the first end of the lamina (6) is being sealed, it is fixedly held in relation to the housing (1). Consequently, the lamina (6) cannot be displaced even during a long period of operation. Subsequent adjustment is therefore unnecessary.
