Abstract (en)

The machine has a cartridge holder (3) and a piston guide (1) with exhaust channel (4). A sealing section (6) defined by propulsion piston (5) and piston guide, is located between the openings of cartridge holder and exhaust channel. The sealing section is formed by the inner wall (9) of a cylindrical recess (8) in a stop face (7) of the piston guide, and the outer wall (12) of a shoulder (11) on the counter face (10) of the piston.

Abstract (de)

Das pulverkraftbetriebene Setzgerät weist eine Kolbenführung (1) mit einer Kartuschenaufnahme (3), einem Abströmkanal (4) und einer Laufbohrung (2) auf, in der ein Treibkolben (5) parallel zur Setzrichtung versetzbar ist. Die Kartuschenaufnahme (3) und der Abströmkanal (4) münden in die Laufbohrung (2). Zwischen der Mündung der Kartuschenaufnahme (3) und dem Abströmkanal (4) ist ein Dichtbereich (6) vorgesehen, der vom Treibkolben (5) und von der Kolbenführung (1) gebildet wird. Dieser zylindrische Dichtbereich (6), sorgt dafür, dass eine Freigabe des Abströmkanals (4) erst nach einer bestimmten Versetzung des Treibkolbens (5) in Setzrichtung erfolgt. <IMAGE>
