ABSTRACT:
A valve system includes a valve body arranged in a valve housing and actuatable via a shape-memory element that is movable from an undeformed rest state to a tension deformed state and is again transferred to the rest state. The valve system is improved by a force deflecting device that enables the shape-memory element to actuate the valve body exclusively during the transfer thereof to the tension or rest state.
