Abstract

Es wird ein miniaturisiertes Kraftelement (10) beschrieben, das ein zylindrisches Führungselement (12) aufweist, in dem ein Arbeitselement (14) vorgesehen ist. Ein Abschlusselement (26) weist eine Zündeinrichtung (32) für einen in einem Ladungsraum (40) des Arbeitselementes (14) vorgesehenen Sprengstoff (42) auf. Das Arbeitselement (14) ist kappenartige mit einer dünnen zylindrischen Seitenwandung (24) ausgebildet und vorzugsweise von einem ziehtechnisch hergestellten Blechteil gebildet. Das Abschlusselement (26), das kappenartige Arbeitselement (14) und das zylindrische, vorzugsweise ebenfalls von einem ziehtechnisch hergestellten Blechteil gebildete Führungselement (12) sind miteinander abdichtend verbunden, vorzugsweise verschweißt. Die dünne zylindrische Seitenwandung (24) des Arbeitselementes (14) weist eine Sollbruchstelle (44) auf.

A miniaturized force element (10) is described which has a cylindrical guide element (12) in which a working element (14) is provided. An end element (26) has an ignition device (32) for an explosive (42) provided in a charge space (40) of the working element (14). The working element (14) is cap-shaped with a thin cylindrical side wall (24) and preferably formed by a sheet metal part produced by way of drawing. The closing element (26), the cap-like working element (14) and the cylindrical guide element (12), which is preferably also formed by a sheet-metal part by way of drawing technology, are sealingly connected to one another, preferably welded. The thin cylindrical side wall (24) of the working element (14) has a predetermined breaking point (44).
