Valve arrangement for opening or closing of e.g. micro valve, has membrane, which separates fluid path between inlet and outlet, and flexible to pressure at inlet and outlet, and has no contact with switching element in other end position

摘要

The arrangement has a valve, which has an inlet and an outlet, which is in fluid connection with the inlet. A switching element between two stable end positions is adjusted back and forth. The switching element (21), in one end position, acts on a membrane (5), in order to close inlet (14) and outlet (16). The membrane separates the fluid path between inlet and outlet and is flexible to the pressure at the inlet and outlet and has no contact with the switching element in the other end position.
