Abstract

The apparatus has a piercing piston (8) which is disposed in a housing (2), can be acted upon by spring force, can be held in an initial position by means of a securing means comprising a releasable detent (10) and can be transferred into an actuating position releasing an energy carrier. To ensure reliable automatic actuation in different cases of disaster, the piercing piston (8) is divided into two with a piston portion (11) which can be locked by the releasable detent (10) and a piston head (12) which is movable in relation to this piston portion by fluid pressure.
