Bei einem bekannten Brennkraftbolzensetzer gäbe wird ausgehend von einem Brennkraftbolzenobiger Art besteht die Brennkammerbuchse, die die setzer der eingangs erwähnten Gattung erfindungsin der Brennkammer erzeugten Pulvergase nur über io gemäß dadurch gelöst, daß die Brennkammerbuchse eine verhältnismäßig kurze axiale Wegstrecke auf den hinten bis auf einen Durchtritt für die Schlagbolzenvorzubewegenden Schubkolben einwirken läßt, aus spitze geschlossen ist, in einem Verschlußstück längseiner axial kurzen, beidendig offenen Hülse, die im verschiebbar angeordnet ist und beim Zünden mit Gerätegehäuse unverschieblich befestigt ist. In diese ihrer dem Schubkolben abgewandten Fläche am Verhülsenartige Brennkammerbuchse ist von vorne der 15 schlußstück anliegt. Die rückwärtig bis auf die enge Schubkolbenkopf einzuschieben, während von hinten Durchtrittsöffnung geschlossene Brennkammer erein verhältnismäßig großmassiger Schlagbolzen möglicht eine wirksame, rückstandsarme Verbrennung hineinragt, der durchmessermäßig mit dem Schub- der Pulvergase, so daß sich in der Brennkammerkolbenkopf übereinstimmt.

Durch den Treibgasrück- 25 und damit auch des gesamten Funktionsverhaltens stoß wird der zuvor im Gerätegehäuse bzw. in der erzielt. Dazu trägt wesentlich auch der Umstand bei, Brennkammerbuchse entsprechend nach vorn ge- daß die Brennkammerbuchse beim Zünden am Verschlagene Schlagbolzen um eine bestimmte Weg- schlußstück anhegt und daher der nach der Zündung strecke zurückbewegt, bevor er auf eine Anschlag- auftretende Rückstoßimpuls sofort von der überfläche im Gerätegehäuse trifft und erst dann also 30 wiegenden Masse des Gerätes aufgenommen wird, seine Rückstoßenergie auf das Gehäuse überträgt. Dadurch wird auch die in der Treibladung steckende Dadurch geht ein Teil der Pulvertreibladungsenergie Energie voll für die Eintreibleistung der Bolzen ausfür die Bolzeneintreibleistung verloren. Nachteilig ist genutzt.In a known internal combustion pin setter, the above would be based on an internal combustion pin Type consists of the combustion chamber socket, which the setters of the genus mentioned in the invention the combustion chamber generated powder gases only about io according to the fact that the combustion chamber liner a relatively short axial distance to the rear except for a passage for the firing pin Plunger can act, is closed from the tip, in a locking piece along its axially short sleeve open at both ends, which is arranged in a displaceable manner and with the ignition Device housing is fixed immovably. In this area on the sleeve-like surface facing away from the thrust piston Combustion chamber bushing is from the front of the 15 closing piece. The back except for the tight one Push in the thrust piston head while the combustion chamber is closed from the rear Relatively large firing pin enables effective, low-residue combustion protrudes, the diameter with the thrust of the powder gases, so that in the combustion chamber piston head matches. This firing pin socket forms only a relatively small amount of powder residue, sits on its inner, the thrust piston head at the same time, the fact that the firing pin with turned end of the cartridge bearing, while at its tip protruding into the combustion chamber, the its outer protruding from the device housing - hit the sensitive point of the cartridge with pinpoint accuracy the end can have an anvil-like thickened impact head and consequently also has little ignition energy, Via the blow of a hand hammer it is necessary, a substantial improvement of the ignition cartridge is ignited. Due to the propellant gas return and thus also the entire functional behavior shock is achieved beforehand in the device housing or in the. The fact that Combustion chamber bushing forwards accordingly that the combustion chamber bushing on the slider when igniting The firing pin is attached to a certain distance piece and therefore the one after the ignition stretched back before responding to a stop-recoil pulse occurring immediately from the surface meets in the device housing and only then is the weight of the device recorded, transfers its recoil energy to the housing. This also removes the amount stuck in the propellant charge As a result, part of the powder propellant charge energy is used entirely for the drive-in power of the bolts the bolt penetration performance is lost. Disadvantage is used.

The firing piston head from the combustion chamber bushing is the mechanism, in particular the firing pin and a relatively large firing pin spring located in the handle of the device housing, in which they flow out obliquely or perpendicular to the device's longitudinal axis or in a hindered manner can, having previously arranged the device run, while the cartridge in the its thrust power is transferred to the thrust piston in the combustion chamber bushing transversely to its axial longitudinal 55. Any discontinuation of powder or gas stretching is arranged or used. Ignition of residues in the spacious loading recess does not interfere with the constant operational readiness of the internal combustion power backward movement of the device barrel or the associated bolt setter, especially since such residues from the firmly connected combustion chamber socket via the loading recess conveniently accessible in the open position at the bottom of the handle - or ignition 60 can be easily removed at any time,
