Abstract (en)

The combustion heat operated setting tool (10), has a holding device (30) with magnetic unit (31), which produces a retaining force for the disc shaped body (17). The combating units are present for combating the retaining force of the magnetic unit. The combustion chamber (14) for an oxidizing agent gaseous combustible mixture with a disc shaped body. The guiding cylinder (12) shifts the setting piston (13).

Abstract (de)

Die vorliegende Erfindung betrifft ein brennkraftbetriebenes Setzgerät (10), zum Eintreiben von Befestigungselementen, wie Nägeln, Bolzen oder Stiften, in einen Untergrund. Dieses weist eine Brennkammer (14) für ein Oxidationsmittel-Brenngasgemisch mit wenigstens einem über zumindest ein Transportmittel (33) axial in der Brennkammer (14) versetzbaren plattenförmigem Körper (17), wobei der plattenförmige Körper (17) über eine Halteeinrichtung (30) gegen das Transportmittel (33) an einem axialen Ende (15) der Brennkammer (14) festlegbar ist auf. An die Brennkammer (14) schliesst sich ein Führungszylinder (12) an, in dem ein Setzkolben (13) versetzbar geführt ist. Zur Verbesserung derartiger Setzgeräte (10) ist die Halteeinrichtung als magnetische Mittel zur Erzeugung einer Haltekraft für den plattenförmigen Körper (17) ausgebildet, wobei Überwindungsmittel zum Überwinden der Haltekraft der magnetischen Mittel (31) vorgesehen sind.
