Abstract

The device comprises an insert housing (1) which has a guide socket (4) on the side opposite to the air intake (2), for a guide rod (5) on the closure plate (7). It also has a closure spring (6) formed as a memory spring, enclosing the guide rod. In open position, the plate is retained on the associated housing side by a heat-sensitive adhesive (8). The closure spring is fastened with one end to the guide socket, and with the other end to the foot of the guide rod and/or the closure plate. The housing cover (11) is enclosed by fire-resistant plates (16).
