Abstract
A valve assembly includes an inlet and an outlet, which open into a working chamber of the valve assembly, and an actuator. In a non-actuated state of the actuator, a flow passage between the inlet and the outlet is blocked. The actuator is optionally a shape-memory actuator that can be actuated one time or comprises a shape-memory actuator, which suddenly changes its external shape upon reaching a conversion temperature, which is dependent on the alloy composition thereof, and which can be generated by a controllable electrical heating device of the valve assembly. The actuator irreversibly destroys a pipe element separating the inlet from the outlet in the working chamber upon actuation, whereby the inlet and the outlet are connected to one another with respect to flow via the working chamber.
