Abstract

A valve includes a housing enclosing a pressure chamber. At least one media opening is closeable via a valve element activated by a wire-shaped SMA element connected at its ends to a printed circuit board and at its middle to the valve element. The wire-shaped SMA element extends in a plane parallel to a direction of movement of the valve element.
