Abstract
The valve seat is located between an inlet opening and an outlet opening, with a connecting stub against which an elastic membrane presses. The membrane is disposed above a cavity and formed by a part of a polysilicon layer. When a medium flows onto the side of the membrane facing the connecting stub, the membrane is lifted off the connecting stub and is pulled into the cavity, so that the medium can flow through the valve. The membrane can be stiffened by a stamp-like attachment, in order to ensure that the valve opens uniformly.
