Abstract

A valve for one-time opening a fluid line for venting a technical system includes an inlet for connecting to the fluid line, an outlet, and a controllable closure arranged between the inlet and the outlet. In the non-activated state the controllable closure closes a passage between the inlet and the outlet. The closure includes a material that changes its phase state in dependence on a control parameter, whereby the passage is irreversibly opened in the activated state.
