- the combustion chamber 1 facing side of the piston plate 9 closes more or less with the inside of the bottom wall 3a, 3b, and the piston rod 10 projects beyond the bottom wall 7 only a little outward.
- the piston plate 9 tapers stepwise toward the combustion chamber 1, with the smaller diameter part coming to lie in the opening 4b and the larger diameter part in the opening 4a.
- the part of the piston plate 9 with a larger diameter thus beats against the bottom plate 3b, which thus serves as a stop for the piston plate 9, when the piston 8 is in its initial position.
- sealing rings on the outer circumference of the piston plate 9 may be provided to seal the spaces 9 on both sides of the piston plate 9 against each other.
- a cylinder plate 14 which may be referred to as a combustion chamber wall.

- the web 2a is only in Fig. 1 fully shown and in the other illustrations in Fig. 2 to 6 omitted for the sake of clarity.
- Fig. 1 At rest of the implement according to Fig. 1 is the partition plate 18 on the bottom wall 3b and the combustion chamber wall 14 on the partition plate 18.
- the combustion chamber. 1 is then completely collapsed.
- the combustion chamber wall 14 When attaching the device against an object, not shown, in which a fastener is to be driven, as will be explained later, the combustion chamber wall 14 is raised and thus moves away from the partition plate 18 and the bottom wall 3b.
- the combustion chamber wall 14 thus takes after a certain time on the annular projection 20, the partition plate 18 with. In this case, then the combustion chamber wall 14 and the partition plate 18 are at a predetermined distance from each other, which is determined by the position of the annular projection 20. In this case, then the combustion chamber wall 14 and the partition plate 18 form a so-called prechamber.
- This pre-chamber carries the reference numeral 21 in Fig. 2 , If the combustion chamber wall 14 is raised even further, the combustion chamber wall 14 and partition plate 18 move parallel to one another, so that between the partition plate 18 and the bottom wall 3b or piston plate 9 spans a further partial combustion chamber, which is referred to as the main chamber.

- damping device 40 At the lower end of the guide cylinder 5 is also a damping device 40 for damping the movement of the piston 8. If the piston 8 passes over the outlet openings 39, exhaust gas can escape from the outlet openings 39.
- In the cylinder wall 2 of the combustion chamber 1 are still two radial through holes 41 and 42, which are spaced apart in the axial direction.
- liquid fuel gas can be injected into the not fully clamped part-combustion chambers 21 and 22, using metering valves, which are connectable to the through holes 41 and 42. In this way, the amount of fuel gas mixture in the respective partial combustion chambers 21 and 22 can be metered.

- the free end of the sensor element 55 thus comes to lie directly in front of the end face 10 a of the piston rod 10, when the piston 8 in accordance with its initial position Fig. 1 located.
- the locking lever 56 and the sensor element 55 may, for. B. be punched out of a sufficiently strong sheet. At the side facing away from the cylinder 5 of the locking lever 56, this has a locking edge 59, with which the locking lever 56 can engage behind the drive ring 28 when it has been moved far enough in the direction of the bottom wall 3a.
- the locking lever 56 Starting from the bearing device 57, therefore, the locking lever 56 initially has a relatively small width, which then increases to form the locking edge 59. With the help of a housing side mounted compression spring 60 of the locking lever 56 is pivoted so in the direction of the cylinder 5 to the bearing means 57 that the locking edge 59 out of engagement with the edge of the opening 58 and the sensor portion 55 comes with its free end in the path of the piston rod 10th lies.

Therefore, if the trigger 61 in Fig. 1 moved counterclockwise to the bearing means 62, the approach 64 is taken accordingly, which then acts on the cylinder 5 facing edge of the locking lever 56 and this according to the force of the spring 60 entrains or pivoted about the bearing device 57.
- Fig. 2 shows a state in which the implement has been pressed with its tip against an object into which a fastener is to be driven.
- the drive ring 28 is thereby displaced in the direction of the combustion chamber 1 via a front-side pressure bar, not shown, and thus biases the partial combustion chambers 21 and 22 via the drive rods 23, whereby the inlet and outlet valve 34 is also closed.
- the pressing bracket, the drive ring 28, the drive rods 23 and the compression springs 27 essentially form a pressing device of the working device, which is located in Fig. 2 is in a contact pressure position. Only in the Anpress ein the pressing device allows the driving of the piston 8 to.
- the trigger 61 is actuated, ie pivoted counterclockwise around the bearing axis 62, against the force of the spring 63.
- the locking lever 56 is pivoted about the bearing 64 counterclockwise about the bearing axis 57, so that the locking edge 59 the Drive ring 28 engages behind.
- the feeler element 55 is moved out of the path of the piston rod 10 with the pivoting of the locking lever 56.
- the ignition of the present in the partial combustion chambers 21 and 22 fuel gas mixture by means of the ignition device 52 takes place.
- the trigger 61 can be released again.
- the locking lever 56 and with it the sensor element 55 are pressed by the compression spring 60 in the direction of the guide cylinder 5, but the locking edge 59 is not out of engagement with the drive ring 28, since the free end of the sensor element 55 is pressed only against the circumference of the piston rod 10 and thus a pivoting of the locking lever 56 in the clockwise direction to the storage device 57 around is not possible.
- the drive ring 28 thus maintains its position, so that the inlet / outlet valve 34 is closed and the partial combustion chambers 21, 22 remain clamped.
- Fig. 4 shows a state after setting or successful combustion of the air-fuel gas mixture in the main chamber 22, wherein the piston 8 is returned by thermal recycling to its initial position, as can be seen by the arrow shown, by cooling in the combustion chamber 1 and in Guide cylinder 5 remaining flue gas a negative pressure behind the piston 8 and behind the piston plate 9 is formed.
- the sensor element 55 continues to grind with its free end on the circumferential surface of the piston rod 10, so that the drive ring 28 remains locked over the locking edge 59 continues.
- the inlet and outlet valve 34 remains closed because the piston 8 has not quite reached its initial position.
- Fig. 5 a state is shown in which the piston 8 has been completely returned by thermal recycling to its initial position.
- the openings 4a and 4b are completely closed by the piston plate.
- the free end 10a of the piston rod 10 has now been withdrawn so far into the guide cylinder 5 that this free end 10a comes to rest outside the range of the sensor element 55.
- the compression spring 60 can pivot the locking lever 56 and with him the sensor element 55 in a clockwise direction about the bearing means 57, so that the locking edge 59 of the locking lever 56 comes out of engagement with the drive ring 28.

Since the holder 101 is fixedly connected to a housing, not shown, of the working device, the bolt guide 102 serves as Anpresspliler and is together with the pressure bar 104 part of a pressing device of the working device.
- the pressing bracket extends in the driving direction beyond the bolt guide and is itself the Anpresspliler.
- a trained as a nail fastener 105 is disposed in a position ready for setting behind the bolt guide and in front of a piston, not shown, of the working device, which is driven for driving the nail 105 into the ground on the nail and guided in a piston guide 106.

- the pressing clip 104 has an actuating element 108 projecting in the driving direction 103.
- Fig. 8 shows the nose 100 of the implement with the feed delay device 110 in a release position, so if the implement is not pressed against a substrate and the piston is in its initial position at rest and, for example, a combustion chamber, not shown, of the implement has collapsed. In favor of a better overview of the guide channel is not shown.
- the operating member 108 is engaged via the control surface 113 with the control member 112 of the lever 111, which is thereby held in the position shown.
- Fig. 9 shows the nose 100 of the implement with the feed delay device 110 in a locked position, that is, when the implement is pressed against a substrate and, for example, the combustion chamber, not shown, of the implement is clamped.
- the actuating element 108 is disengaged from the control element 112.
- a spring element, not shown, for example, a torsion spring exerts a bias on the lever 111 in a clockwise direction, so that the control element 112 in Fig. 9 moved upwards.
- Fig. 10 is a perspective view of the nose 100 of the implement with the feed delay device 110 in the release position according to Fig. 8 ,
- the strip 107 with the nails 105 is transported here from below into the guide channel, not shown.
- the actuator 108 is in turn via the control surface 113 in engagement with the control element 112 of the lever 111, which is thereby held in the position shown.
- the lever 111 has a toothed abutment surface 115 for abutment with the nail 105 or the strip 107, from which it is, however, spaced in the release position of the feed delay device 110 shown.
- a transport of the nail 105 in the guide channel, not shown, is therefore allowed.
- Fig. 11 is a perspective view of the nose 100 of the implement with the feed delay device 110 in the locked position according to Fig. 9 , As a result, the actuating element 108 is again out of engagement with the control element 112, so that the control element 112 due to the bias of the spring element, not shown in FIG Fig. 11 has moved to the left.
- the contact surface 115 is now on the nail 105 and / or the strip 107, so that in the blocking position of the feed delay device 110 shown a transport of the nail 105 is locked in the guide channel, not shown.
- the detection device is a movement of the Anpressbügels 104 back to the position in accordance Fig. 10 free only when the piston is in its initial position at rest. This ensures that the feed of the fastener is delayed until a possibly existing reciprocating movement of the piston is completed.

- the strip is thereby clamped by the force of the spring element, not shown, against a likewise not shown support element, which is for example firmly connected to the holder or the housing of the implement or the magazine.
- the blocking position of the feed delay device 110 shown is a transport of in Fig. 13 second nail 105 locked from the left in the guide channel, not shown, even if the left nail after a driving operation is no longer available and the piston has released the guide channel.
- the third, fourth or fifth nail or the strip is clamped at one point between two nails.
- the toothing of the contact surface 115 has a Preferred direction (see Fig. 12 ), so that the strip 107, despite the blocking position manually to the right from the position shown pulled out, for example, in case of malfunction of the implement.
- the contact surface is flat or gently curved and is only frictionally on the fastener or the strip.
- the feed delay described is independent of how quickly a user lifts the implement from the ground again and is therefore not exposed to the user's behavior.
- the guide channel can be moved independently of the feed delay device, so for example, when lifting off the ground due to decoupling from the rest of the implement still pending on the ground, which may improve the Eintreib243.
- the guide channel is then a simple design wear part.
- the feed delay is independent of the type of piston drive and can also be used in implements with non-collapsing combustion chambers.

Zwischen der Brennkammerwand 14 und der Bodenwand 3b befindet sich eine weitere Trennplatte 18. Die Trennplatte 18 ist ebenfalls kreisförmig ausgebildet und weist einen Aussendurchmesser auf, der dem Innendurchmesser der Brennkammer 1 entspricht. An der zur Brennkammerwand 14 weisenden Seite ist die Trennplatte 18 mit einem zylindrischen Ansatz 19 verbunden, der durch die zentrale Durchgangsöffnung 16 der Brennkammerwand 14 hindurchragt und dessen Länge einem mehrfachen der Dicke der Brennkammerwand 14 entspricht. Die genannte Umfangsdichtung entlang der Durchgangsöffnung 16 schmiegt sich dabei dicht an die Aussenumfangsfläche des zylindrischen Ansatzes 19 an. An seinem oberen Ende weist der zylindrische Ansatz 19 einen seinen Umfang überragenden ringförmigen Ansatz 20 auf. Der Aussendurchmesser des ringförmigen Ansatzes 20 ist grösser als der Innendurchmesser der Durchgangsöffnung 16. Am Rand der Durchgangsöffnung 16 ist mit der Brennkammerwand 14 ein hohlzylindrischer Ansatz 17 verbunden, der den zylindrischen Ansatz 19 umgibt. Das freie Ende des hohlzylindrischen Ansatzes 17 liegt dabei der unteren Seite des ringförmigen Ansatzes 20 gegenüber und in
Im Ruhezustand des Arbeitsgeräts gemäss
Zur Verschiebung der Brennkammerwand 14 in Längsrichtung der Brennkammer 1 sind mit der Brennkammerwand 14 über deren Umfang unter gleichen Winkelabständen verteilt z. B. drei Antriebsstangen 23 fest verbunden, von denen nur eine in der Zeichnung zu erkennen ist. Die Antriebsstangen 23 liegen parallel zur Zylinderlängsachse der Brennkammer 1 und aussen seitlich zur Zylinderwand 6. Dabei durchlaufen die Antriebsstangen 23 jeweils eine Durchgangsöffnung 24 in der Trennplatte 18 sowie eine weitere Durchgangsöffnung 25a, 25b in der Bodenwand 3a, 3b. Diese Durchgangsöffnung 25a, 25b ist gleichzeitig als Ventilöffnung ausgebildet und besitzt im Bereich 25a einen konischen Verlauf. Die Antriebsstangen 23 und die Brennkammerwand 14 sind z. B. in geeigneter Weise über Schrauben miteinander verbunden, während die freien Enden der Antriebsstangen 23 über einen Antriebsring 28 miteinander verbunden sind, der konzentrisch zur Zylinderachse der Brennkammer liegt und den Führungszylinder 5 umgreift. Auch der Antriebsring 28 kann über Schrauben mit den Antriebsstangen 23 verschraubt sein. Zwischen dem Antriebsring 28 und aussen fest an der Zylinderwand 6 angebrachten Ansätzen 26, durch die jeweils eine der Antriebsstangen 23 hindurchläuft, liegt auf jeder der Antriebsstangen 23 eine Druckfeder 27, die sich am jeweiligen Ansatz 26 abstützt sowie gegen den Antriebsring 28 drückt. Diese Druckfedern 27 sind daher bestrebt, die Brennkammerwand 14 immer in Richtung zur Bodenwand 3b zu drücken.For displacement of the
Wie bereits erwähnt, befindet sich im Bereich der ringförmigen Bodenwand 3a, 3b die als Ventilöffnung dienende Durchgangsöffnung 25a, 25b, die sich aussen (25a) konisch erweitert. In diese Ventilöffnung ist ein Ventilstössel 32 dichtend einführbar. Dieser Ventilstössel 32 liegt bei geöffneter Ventilöffnung 25a, 25b ausserhalb der Brennkammer 1 bzw. unterhalb der Bodenwand 3a und wird in dieser Stellung über einen am Führungszylinder 5 befestigten Ansatz 33a blockiert. Zwischen dem Ventilstössel 32 und dem Rand der Öffnung 25a liegt eine Druckfeder 33b, die den Ventilstössel 32 gegen den Ansatz 33a drückt. Wird der Antriebsring 28 in Richtung der Bodenwand 3a verschoben, so nimmt ein an der Antriebsstange befestigter Ansatz 33 den Ventilstössel 32 mit und führt ihn gegen den Druck der Feder 33b in die Ventilöffnung 25a, 25b ein, um das Ventil zu schliessen, das das Bezugszeichen 34 trägt. Es handelt sich hier um ein Ein-/Auslassventil. Dabei durchfährt der Ansatz 33 eine im Ansatz 33a vorhandene Öffnung 33c.As already mentioned, in the area of the
Es sei noch erwähnt, dass die Trennplatte 18 umfangsseitig mehrere Durchgangsöffnungen 38 aufweist, die jeweils den gleichen Abstand von der Zylinderachse der Brennkammer 1 haben können. Ferner befinden sich am unteren Ende des Führungszylinders 5 Auslassöffnungen 39 zum Auslass von Luft aus dem Führungszylinder 5, wenn der Kolben 8 in Richtung zur Bodenwand 7 bewegt wird. Am unteren Ende des Führungszylinders 5 befindet sich darüber hinaus eine Dämpfungsvorrichtung 40 zur Dämpfung der Bewegung des Kolbens 8. Überfährt der Kolben 8 die Auslassöffnungen 39, so kann Abgas aus den Auslassöffnungen 39 entweichen. In der Zylinderwand 2 der Brennkammer 1 befinden sich noch zwei radiale Durchgangsöffnungen 41 und 42, die in Axialrichtung voneinander beabstandet sind. Über sie kann flüssiges Brenngas in die noch nicht voll aufgespannten Teil-Brennkammern 21 und 22 eingespritzt werden, und zwar unter Verwendung von Dosierventilen, die mit den Durchgangsöffnungen 41 und 42 verbindbar sind. Auf diese Weise lässt sich die Menge an Brenngasgemisch in den jeweiligen Teil-Brennkammern 21 und 22 dosiert vorgeben.It should also be mentioned that the

Weiterhin ist seitlich am Zylinder 5 ein als Abzug bzw. Trigger ausgebildeter Auslöser 61 vorhanden, der an der Aussenseite der Zylinderwand 6 schwenkbar gelagert ist. Hierzu ist eine Lagereinrichtung 62 vorgesehen. Der Auslöser 61 kann in Richtung zur Bodenwand 3a, 3b um die Lagereinrichtung 62 verschwenkt werden, und zwar gegen die Druckkraft einer Druckfeder 63. Ein Betätigungsabschnitt des Auslösers 61 kommt dabei ausserhalb des Verriegelungshebels 56 zu liegen. Darüber hinaus ist der Auslöser 61 im Bereich der Lagereinrichtung 62 mit einem in Richtung zum Boden 7 des Zylinders 5 weisenden Ansatz 64 z. B. einstückig verbunden. Wird daher der Auslöser 61 in

Dieser hohe Druck wird auf die Kolbenplatte 9 übertragen, so dass diese sich mit hoher Geschwindigkeit in Richtung zur Bodenwand 7 bewegt, wobei gleichzeitig die Luft aus dem Führungszylinder 5 durch die Auslassöffnungen 39 nach aussen getrieben wird. Die Kolbenplatte 9 überfährt kurzzeitig die Auslassöffnungen 39, so dass durch sie Abgas entweichen kann. Durch die in Pfeilrichtung ausfahrende Kolbenstange 10 wird jetzt ein Befestigungselement gesetzt bzw. in den Gegenstand hineingetrieben, gegen den das Arbeitsgerat gedrückt worden ist. Die Brennkammer 1, die Zündvorrichtung 52 und weitere Elemente bilden somit eine Antriebseinrichtung zum Antreiben des Kolbens auf das Befestigungselement zu.This high pressure is transmitted to the

In einem nicht weiter dargestellten nächsten Schritt kann nunmehr der Antriebsring 28 mit Hilfe der Druckfedern 27 von der Bodenwand 3a, 3b weggeschoben werden, was zur entsprechenden Mitnahme der Antriebsstangen 23 führt. Der Ansatz 33 bewegt sich somit ebenfalls von der Bodenwand 3a, 3b weg, so dass der Ventilstössel 32 aus der Ventilöffnung 25a, 25b herausgeführt werden kann, und zwar unter Wirkung der Druckfeder 33b. Im Zuge der Verschiebung der Antriebsstangen 23 in Richtung zum vorderen Ende des Arbeitsgeräts werden zunächst die Brennkammerwand 14 und dann die Trennplatte 18 entsprechend mitgenommen, so dass die gesamte Brennkammer 1 bzw. die Teil-Brennkammem 21, 22 kollabieren. Dabei werden die verbrannten Restgase durch das Ein- und Auslassventil 34 ausgegeben. Dieses Ein- und Auslassventil 34 dient auch der Zufuhr von Frischluft in die Brennkammer 1 bei entgegengesetzter Bewegung der Platten 14 und 18, wie
Ein als Nagel 105 ausgebildetes Befestigungselement ist in einer setzbereiten Position hinter der Bolzenführung und vor einem nicht gezeigten Kolben des Arbeitsgeräts angeordnet, welcher zum Eintreiben des Nagels 105 in den Untergrund auf den Nagel zu angetrieben und in einer Kolbenführung 106 geführt ist. Der Nagel 105 ist zusammen mit weiteren Nägeln in einem Streifen 107 insbesondere aus Kunststoff gehalten, welcher in einem nicht gezeigten Magazin aufgenommen ist und von einer in dem Magazin angeordneten Vorschubeinrichtung auf den Führungskanal zu, also in
Eine insgesamt mit 110 bezeichnete Vorschubverzögerungseinrichtung umfasst einen Hebel 111, welcher ein Steuerelement 112 mit einer gegenüber der Eintreibrichtung 103 geneigten Steuerfläche 113 umfasst und über einen Zapfen 114 drehbar an dem Halter 101 gelagert ist. Bei nicht gezeigten Ausführungsbeispielen ist der Hebel ebenfalls als Schwenkhebel und/oder als Schiebehebel ausgebildet, welcher beispielsweise als Schlitten verschiebbar an dem Halter gehalten ist. Zur Betätigung des Steuerelements 112 weist der Anpressbügel 104 ein in Eintreibrichtung 103 vorspringendes Betätigungselement 108 auf.A feed delay device, generally designated 110, comprises a
Die beschriebene Vorschubverzögerung ist unabhängig davon, wie schnell ein Benutzer das Arbeitsgerät vom Untergrund wieder abhebt und ist somit nicht dem Bedienungsverhalten des Benutzers ausgesetzt. Darüber hinaus kann der Führungskanal unabhängig von der Vorschubverzögerungseinrichtung bewegt werden, also beispielsweise beim Abheben vom Untergrund aufgrund einer Entkoppelung vom restlichen Arbeitsgerät noch am Untergrund anstehen, wodurch unter Umständen die Eintreibqualität verbessert ist. Ausserdem ist der Führungskanal dann ein einfach gestaltbares Verschleissteil. Weiterhin ist die Vorschubverzögerung unabhängig von der Art des Kolbenantriebs und ist auch bei Arbeitsgeräten mit nichtkollabierenden Brennkammern einsetzbar.The feed delay described is independent of how quickly a user lifts the implement from the ground again and is therefore not exposed to the user's behavior. In addition, the guide channel can be moved independently of the feed delay device, so for example, when lifting off the ground due to decoupling from the rest of the implement still pending on the ground, which may improve the Eintreibqualität. In addition, the guide channel is then a simple design wear part. Furthermore, the feed delay is independent of the type of piston drive and can also be used in implements with non-collapsing combustion chambers.
