Abstract

A detector comprises a metallic casing (1) which is closed and sealed by a cover (2) in which there is a hole (12) for connexion to a valve. The bottom of the casing comprises an orifice (3) with the sides forming the seat (8) for a clacker. The sound emitter is a hammer (10) which has an enlarged top (11) and which is sealed by a circular membrane (9). It also seals the clacker (7) which rests on the seat (8). Gas depressions in the casing cause the membrane to deform to lift the hammer, subsequent depressions raise the clacker and cause it to fall thus emitting a sound.
