Abstract

A separating arrangement between multipart constructional elements, including an expansion chamber for at least one pyrotechnic charge which is bounded by the piston surface of a displacement or sliding piston. The separating arrangement has at least one gas passageway which communicates with the expansion chamber, through the intermediary of which a separating piston can be subjected to pressure. The combustion gas pressure of the pyrotechnic charges acts within the expansion chamber against different piston surfaces and thereby, in a constructively predeterminable manner, effects different successive piston movements, as a result of which the sequence of the individual separating operations which can be carried out in different directions predeterminably in a definite manner and functionally-dependent.
