'Druckmittelbetriebene Austreibvorrichtung' 'Pressure medium driven expelling device'
Die Erfindung betrifft eine druckmittelbetriebene Austreibvorrichtung zum Austreiben von Gegenständen oder fluiden Stoffen aus einem Reservoir mittels eines druckmittelbeaufschlagtem Treibkolbens mit einem über eine Druckanschlussvorrichtung austauschbar mit der Austreibvorrichtung verbundenen Druckmittelspeicher zur Druckmittelbeauf- schlagung des Treibkolbens.The invention relates to a fluid-driven expulsion device for expelling objects or fluids from a reservoir by means of a pressure medium-loaded drive piston with a via a pressure connection device interchangeable with the expelling connected pressure fluid accumulator for Druckmittelbeauf- tion of the drive piston.
Eine Vorrichtung der eingangs genannten Art in der Ausführung als Schlaggerät zum Eintreiben mechanischer Befestigungsmittel, wie beispielsweise Stahlstifte, ist aus der WO 03/002308 Al bekannt. Bei der bekannten Vorrichtung ist der Druckmittelspeicher unmittelbar an einen Gerätekörper der Austreibvorrichtung angeschlossen. Der Druckmittelspeicher ermöglicht einen netzunabhängigen Betrieb der Austreibvorrichtung, sodass die Austreibvorrichtung zu ihrem Betrieb nicht an eine stationäre Druckquelle angeschlossen werden muss. Dies ermöglicht insbesondere in den Fällen, in denen häufige Positionswechsel mit der Austreibvorrichtung vorzunehmen sind, eine erheblich vereinfachteA device of the type mentioned in the embodiment as impact device for driving mechanical fastening means, such as steel pins, is known from WO 03/002308 Al. In the known device, the accumulator is connected directly to a device body of Austreibvorrichtung. The accumulator allows a network-independent operation of the expulsion device, so that the Austreibvorrichtung must not be connected to a stationary pressure source for their operation. This allows a considerably simplified, in particular, in the cases where frequent position changes are to be made with the expulsion device
Handhabung der Austreibvorrichtung. In anderen Einsatzfällen, in denen der Betrieb der Austreibvorrichtung überwiegend in unveränderter Position erfolgt oder die mechanischen Befestigungsmittel nur unter sehr hohem Kraftaufwand eintreibbar sind, kann es sich jedoch auch als vorteilhaft erweisen, eine Austreibvorrichtung zu verwenden, die an eine stationäre Druckluftquelle angeschlossen ist, da in diesen Fällen das begrenzte Volumen eines Druckmittelspeichers nur eine entsprechend kurze Betriebszeit der Austreibvorrichtung ermöglichen würde.Handling the expelling device. In other applications where However, it may also prove advantageous to use a Austreibvorrichtung which is connected to a stationary source of compressed air, since in these cases the limited volume of the Austreibvorrichtung predominantly in unchanged position or mechanical fasteners can be driven only with very high force a pressure medium storage only a correspondingly short operating time of the expulsion device would allow.
Um je nach Einsatzbedingungen die jeweils günstigeren Arbeitsbedingungen für den Anwender zu ermöglichen, ist es bislang notwendig zwischen einer mit einem Druckmittelspeicher versehenen Austreibvorrichtung und einer zum Anschluss an eine stationäre Druckluftquelle geeigneten Austreibvorrichtung zu wählen, sodass zumindest zwei entsprechend unterschiedlich ausgebildete Austreibvorrichtungen mit den damit verbundenen, entsprechend hohen Anschaffungskosten bereitzu- stellen sind.In order to enable the user in each case more favorable working conditions depending on the conditions of use, it has heretofore been necessary to choose between an expulsion device provided with a pressure fluid accumulator and an expelling device suitable for connection to a stationary compressed air source, so that at least two suitably differently configured expelling devices are connected to the associated expulsion devices. correspondingly high acquisition costs.
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, den Bereitstellungsaufwand zur Durchführung von mit druckmittelbetriebenen Austreibvorrichtungen durchführbaren Arbeiten zu reduzieren.The present invention is based on the object to reduce the deployment effort to carry out feasible with fluid-powered Austreibvorrichtungen work.
Zur Lösung dieser Aufgabe weist die erfindungsgemäße Austreibvorrich- tung eine Druckanschlussvorrichtung auf, die sowohl zum Anschluss des Druckmittelspeichers als auch zum Anschluss an eine stationäre Druckquelle dient.In order to achieve this object, the expelling device according to the invention has a pressure connection device which serves both to connect the pressure medium reservoir and to connect to a stationary pressure source.
Erfindungsgemäß wird somit eine Austreibvorrichtung vorgeschlagen, die je nach Arbeits- oder Einsatzbedingungen sowohl ein Netzbetrieb, also einen an eine stationäre Druckquelle angeschlossenen Betrieb, als auch eine netzunabhängigen Betrieb, also einen Betrieb basierend auf dem durch den Druckmittelspeicher definierten Druckluftreservoir, ermöglicht. Bei einer besonders bevorzugten Ausführungsform der Austreibvorrich- tung weist die Druckanschlussvorrichtung eine Druckminderereinrichtung auf, die sowohl vom Druckmittelspeicher als auch von der stationären Druckquelle her mit Druck beaufschlagbar ist. Hierdurch kann bei voreingestelltem Arbeitsdruck zum Betrieb der Austreibvorrichtung beliebig zwischen dem Anschluss an die stationäre Druckquelle oder den Druckmittelspeicher gewählt werden, ohne eine einmal an die Arbeitsbedingungen angepasste Einstellung des Arbeitsdrucks ändern zu müssen.According to the invention, therefore, an expulsion device is proposed which, depending on the working or operating conditions, enables both a network operation, ie an operation connected to a stationary pressure source, and a network-independent operation, ie an operation based on the compressed air reservoir defined by the pressure medium reservoir. In a particularly preferred embodiment of the expelling device, the pressure connection device has a pressure reducing device which can be pressurized both by the pressure medium reservoir and by the stationary pressure source. As a result, can be selected at a preset working pressure to operate the expelling device arbitrarily between the connection to the stationary pressure source or the pressure medium storage without having to change once adjusted to the working conditions adjustment of the working pressure.
Wenn die Druckminderereinrichtung an eine Druckkammer angeschlos- sen ist, die über einen ersten Druckanschluss mit dem Druckmittelspeicher und einen zweiten Druckanschluss mit der stationären Druckquelle verbindbar ist, ist sichergestellt, dass sowohl der durch das Druckluftreservoir des Druckmittelspeicher generierte Speicherdruck als auch der durch die stationäre Druckquelle generierte Netzdruck in gleicher Weise auf die Druckminderereinrichtung wirken.If the pressure reducing device is connected to a pressure chamber which can be connected via a first pressure connection to the pressure medium reservoir and a second pressure connection to the stationary pressure source, it is ensured that both the storage pressure generated by the compressed air reservoir of the pressure medium reservoir and by the stationary pressure source Generated network pressure act in the same way on the pressure reducer.
Wenn in der Druckverbindung zwischen der Druckminderereinrichtung und dem Druckmittelspeicher eine weitere Druckminderereinrichtung angeordnet ist, kann sichergestellt werden, dass bei einem Wechsel zwischen dem Druckspeicherdruck und dem Netzdruck zum Betrieb der Austreibvorrichtung keine schädlichen Druckspitzen auftreten.If a further pressure reducing device is arranged in the pressure connection between the pressure reducer device and the pressure medium accumulator, it can be ensured that no detrimental pressure peaks occur during a change between the pressure accumulator pressure and the network pressure for operating the expelling device.
Als besonders vorteilhaft erweist es sich, wenn die Druckanschlussvorrichtung einen Geräteanschlusskörper und einen Speicheranschlusskörper aufweist, die über eine Druckleitung miteinander verbunden sind, wobei der Geräteanschlusskörper zum Anschluss an die Austreibvorrichtung und der Speicheranschlusskörper zum Anschluss an den Druckmittelspeicher dient. Hierdurch ist es möglich, zur Ausbildung der Druckanschlussvorrichtung separate Anschlusseinheiten vorzusehen, die örtlich unabhängig voneinander in den jeweils günstigsten Positionen an der Austreibvorrichtung angeordnet werden können. Wenn darüber hinaus der Geräteanschlusskörper zur Anordnung eines Druckanschlusses für die stationäre Druckquelle und zur Anordnung der ersten Druckminderereinrichtung dient, und der Speicheranschlusskörper zu Anordnung eines Druckanschlusses für den Druckmittelspeicher und zur Anordnung der zweiten Druckminderereinrichtung dient, ist eine unmittelbare Zuordnung der Druckminderereinrichtungen zu den mit ihnen zusammenwirkenden Einrichtungen der Austreibvorrichtung möglich, sodass etwa Bedienungsfehler der Austreibvorrichtung durch ein Verwechseln der Druckminderereinrichtungen auszuschließen sind.It proves to be particularly advantageous if the pressure connection device has a device connection body and a memory connection body which are connected to one another via a pressure line, wherein the device connection body serves for connection to the expelling device and the storage connection body for connection to the pressure medium reservoir. This makes it possible to provide for the formation of the pressure connection device separate connection units, which can be arranged locally independently of each other in the most favorable positions on the expulsion device. In addition, when the device connector body is for arranging a pressure port for the stationary pressure source and for disposing the first pressure reducer, and the memory port body is for disposing a pressure port for the pressure fluid reservoir and for disposing the second pressure reducer, then the pressure reducers are directly associated with those cooperating with them Facilities of Austreibvorrichtung possible, so about operator errors of Austreibvorrichtung be excluded by confusing the pressure reducer devices.
Wenn der Speicheranschlusskörper als Tragkonsole zur Aufnahme des Druckmittelspeichers ausgebildet ist, erfüllt der Speicheranschlusskörper gleichzeitig die Funktion einer mechanischen Kupplungseinrichtung zur Verbindung des Druckmittelspeichers mit der Austreibvorrichtung.If the storage connection body is designed as a support bracket for receiving the accumulator, the accumulator body simultaneously fulfills the function of a mechanical coupling device for connecting the accumulator with the Austreibvorrichtung.
Wenn der Speicheranschlusskörper darüber hinaus an einer mit einem Gerätekörper der Austreibvorrichtung verbundenen Magazinvorrichtung angeordnet ist, kann der Gerätekörper der Austreibvorrichtung selbst identisch gestaltet sein mit einem Gerätekörper einer Austreibvorrichtung, die ausschließlich zum Anschluss an eine stationäre Druckluftquelle bestimmt ist.In addition, when the storage port body is disposed on a magazine device connected to an apparatus body of the expelling device, the apparatus body of the expelling device itself may be identically configured with an apparatus body of an expelling device exclusively for connection to a stationary compressed air source.
Als besonders vorteilhaft hinsichtlich der Handhabung der Austreibvorrichtung erweist es sich, wenn der Speicheranschlusskörper derart an der Magazinvorrichtung angeordnet ist, dass sich der Druckmittelspeicher längs der Magazinvorrichtung erstreckt, sodass das Bauvolumen der mit einem Druckmittelspeicher versehenen Austreibvorrichtung sich im Wesentlichen nicht von dem Bauvolumen einer ausschließlich für den Anschluss an eine stationäre Druckluftquelle bestimmten Austreibvorrichtung unterscheidet.It proves to be particularly advantageous with regard to the handling of the expelling device, when the storage connection body is arranged on the magazine device such that the pressure medium accumulator extends along the magazine device, so that the construction volume of the expelling device provided with a pressure medium accumulator essentially does not depend on the construction volume of exclusively for distinguishes the connection to a stationary compressed air source certain expelling device.
Als besonders vorteilhaft wirkt es sich auch auf die Betriebssicherheit der Austreibvorrichtung aus, wenn sich der Druckmittelspeicher zumin- dest mit einem Teilbereich durch eine mit der Magazinvorrichtung verbundene Protektoreinrichtung erstreckt, sodass der Druckmittelspeicher vor äußeren Beschädigungen geschützt ist. Darüber hinaus kann je nach Ausbildung der Protektoreinrichtung diese auch zur statischen Abstützung des Druckmittelspeichers beitragen.It also has a particularly advantageous effect on the operational safety of the expelling device when the pressure medium accumulator is at least partially connected to the magazine device connected protector device extends so that the accumulator is protected from external damage. In addition, depending on the design of the protector device, these also contribute to the static support of the accumulator.
Als besonders einfach in der Ausgestaltung sowie auch besonders effektiv in ihrer Wirkung erweist sich eine Protektoreinrichtung, die durch eine sich peripher zum Querschnittsumfang erstreckende Bügeleinrichtung gebildet ist.A protector device that is formed by an ironing device extending peripherally to the cross-sectional circumference proves to be particularly simple in design and also particularly effective in its effect.

Bei anstehen- dem Arbeitsdruck erfolgt durch eine Betätigung des Abzugshebels 21 eine Beaufschlagung der Stahlstifte 24 durch den Austreibbolzen 26 der Treibkolbeneinheit 12, sodass der Stahlstift 24 aus dem Austreibkanal 25 herausgetrieben wird.The magazine device 13 has arranged in a dash-dotted line here housing channel 36 of the magazine housing 19 arranged in a series combination number of steel pins 24, which are each arranged with its longitudinal axis parallel to the axis of Austreibkanals 25 and arranged in the magazine device 13, here axial propulsion device not shown are forced into a final position in the drive channel 25. When the working pressure is applied, an actuation of the trigger lever 21 causes the steel pins 24 to be acted upon by the expulsion bolt 26 of the drive piston unit 12, so that the steel pin 24 is driven out of the drive-out channel 25.
Wie insbesondere Fig. 1 zeigt, ist der Geräteanschlusskörper 15 flansch- artig mit dem freien Ende des Handgriffteils 18 verbunden und weist hierzu, wie Figur 5 zeigt, drei Befestigungsbohrungen 27 auf, die zur Durchführung nicht näher dargestellter Befestigungsschrauben dienen. Wie weiter aus einer Zusammenschau der Figuren 1, 4 und 5 deutlich wird, weist der Geräteanschlusskörper 15 neben dem Druckanschluss 20, der zur Verbindung mit einer stationären Druckluftquelle dient, einen Druckanschluss 28 auf, der über die damit verbundene Druckleitung 17 zum Anschluss des Druckmittelspeichers 23 an den Geräteanschlusskörper 15 dient. Der Druckanschluss 20 und der Druckanschluss 28 sind über eine im Geräteanschlusskörper 15 angeordnete Ventileinrichtung 29 miteinander verbunden, die je nach Schaltstellung ihres Ventilelements 30 eine Druckluftverbindung zwischen dem Druckanschluss 28 und einer zur Treibkolbeneinheit 12 der Austreibvorrichtung 10 führenden Arbeitsdruckkanal 31 oder dem Druckanschluss 20 und der Arbeitsdruckkanal 31 ermöglicht. Der Arbeitsdruckkanal 31 mündet in der Darstellung gemäß Figur 5 in einen Ventilraum 32, in dem das Ventilelement 30 zwischen zwei Schaltstellungen bewegbar ist. An einem in der Darstel- lung gemäß Fig. 5 hinter der Ventileinrichtung 29 angeordneten Druckraum 33 ist eine in Figur 1 dargestellte Druckminderereinrichtung 34 angeschlossen. In den Druckraum 33 mündet schließlich ein Arbeitsdruckkanal 35, der sich durch den Handgriffteil 18 bis hin zur Treibkol- beneinheit 12 zur Beaufschlagung des Austreibbolzens 26 mit Arbeitsdruck fortsetzt.As shown particularly in FIG. 1, the device connection body 15 is flange-like connected to the free end of the handle portion 18 and has, as Figure 5 shows, three mounting holes 27, which serve to carry out not shown fastening screws. As is further clear from a comparison of FIGS. 1, 4 and 5, the device connection body 15 has, in addition to the pressure connection 20, which serves for connection to a stationary compressed air source, a pressure connection 28, which via the pressure line 17 connected thereto for connection of the pressure medium reservoir 23 to the device connector body 15 is used. The pressure port 20 and the pressure port 28 are connected to each other via a device arranged in the device body 15 valve means 29, depending on the switching position of its valve member 30, a compressed air connection between the pressure port 28 and a drive piston unit 12 of the expelling 10 leading working pressure channel 31 or the pressure port 20 and the working pressure channel 31 allows. The working pressure channel 31 opens in the illustration according to FIG 5 in a valve chamber 32 in which the valve element 30 is movable between two switching positions. At one in the depiction According to FIG. 5, pressure chamber 33 arranged behind valve device 29 is connected to a pressure reducing device 34 shown in FIG. Finally, a working pressure channel 35, which continues through the handle part 18 as far as the driving piston unit 12 for acting on the expelling bolt 26 with working pressure, opens into the pressure chamber 33.
Der Ventilraum 32 ist in einer Gehäusebohrung 37 des Geräteanschluss- körpers 15 ausgebildet, die nach außen hin durch einen Bohrungsstopfen 38 verschlossen ist. In der Gehäusebohrung 37 ist ein hülsenförmig ausgebildetes Ventilsitzelement 40 angeordnet, das durch eine zwischen dem Bohrungsstopfen 38 und dem Ventilsitzelement 40 angeordnete Abstandshülse 39 zur Positionierung gegen einen Bohrungsabsatz 41 gedrückt wird. Auf der gegenüberliegenden Seite des Ventilraums 32 ist ein weiterer Bohrungsabsatz ausgebildet, der als Gehäuseventilsitz 42 dient. Die Schaltstellungen des Ventilelements 30 sind also einerseits durch Anlage des Ventilelements gegen das Ventilsitzteil 39 und andererseits durch Anlage des Ventilelements gegen den Gehäuseventilsitz 42 definiert. In der in Fig. 5 dargestellten Ausführungsform weist das Ventilelement einen zylinderstiftartig ausgebildeten Ventilkörper mit einer radial darauf angeordneten Ventildichtung 44 auf. Zur Fluidverbin- dung zwischen dem Druckanschluss 20 und dem Ventilraum 32 ist die Hülse mit Wandungsbohrungen 45 versehen, die eine Fluidverbindung mit dem Druckanschluss 20 ermöglichen.The valve chamber 32 is formed in a housing bore 37 of the Geräteanschluss- body 15, which is closed to the outside by a bore plug 38. In the housing bore 37, a sleeve-shaped valve seat member 40 is arranged, which is pressed by a disposed between the bore plug 38 and the valve seat member 40 spacer sleeve 39 for positioning against a bore 41. On the opposite side of the valve chamber 32, a further bore paragraph is formed, which serves as a housing valve seat 42. The switching positions of the valve element 30 are therefore defined on the one hand by contact of the valve element against the valve seat part 39 and on the other hand by abutment of the valve element against the housing valve seat 42. In the embodiment illustrated in FIG. 5, the valve element has a valve body formed in the manner of a cylinder pin with a valve seal 44 arranged radially thereon. For fluid communication between the pressure port 20 and the valve space 32, the sleeve is provided with wall bores 45, which allow fluid communication with the pressure port 20.
Zur eindeutigen Definition einer bestimmten Schaltstellung im Fall einer Druckbeaufschlagung des Druckanschlusses 20 und des Druckanschlusses 28 ist der über den Druckanschluss 28 vom Druckmittelspeicher 23 mittel einer, wie in Fig. 6 dargestellt, im Speicheranschlusskörper 16 angeordneten Druckminderereinrichtung 46 grundsätzlich höher eingestellt, als der von der stationären Druckluftquelle über den Druckan- Schluss 20 auf das Ventilelement 30 wirkende Ventildruck. Beispielsweise kann der am Druckanschluss 28 anliegende Druck auf 15 bar einge- stellt sein, der somit höher ist als der üblicherweise auf 8 bar eingestellte Druck einer stationären Druckluftquelle.For a clear definition of a particular switching position in the case of pressurization of the pressure port 20 and the pressure port 28 of the pressure port 28 from the pressure medium storage means 23, as shown in Fig. 6, arranged in the accumulator body 16 pressure reducer 46 is generally set higher than that of the stationary compressed air source via the pressure-20 on the valve element 30 acting valve pressure. For example, the pressure applied to the pressure port 28 can be reduced to 15 bar. be, which is thus higher than the usually set to 8 bar pressure of a stationary compressed air source.
Wie eine Zusammenschau der Fig. 3, 4 und 6 zeigt, ist der an dem Magazingehäuse 19 der Magazinvorrichtung 13 angeordnete Speicheran- schlusskörper 16 neben der Druckminderereinrichtung 46, die in Fluid- verbindung zwischen dem Druckanschluss 22 und einem Anschlussstutzen 48 für die Druckleitung 17 angeordnet ist, mit einem Sicherheitsventil 49 zur Unterbrechung einer Druckverbindung zwischen dem Druckmittelspeicher 23 und der Druckminderereinrichtung 46 versehen. Au- ßerdem ist der Speicheranschlusskörper 16 im vorliegendem Fall noch einen Füllstandsanzeiger 50 zur Anzeige des aktuell im Druckmittelspeicher 23 enthaltenen Volumens versehen.3, 4 and 6, the storage connection body 16 arranged on the magazine housing 19 of the magazine device 13 is arranged next to the pressure reducing device 46, which is in fluid communication between the pressure connection 22 and a connection piece 48 for the pressure line 17 is provided with a safety valve 49 for interrupting a pressure connection between the accumulator 23 and the pressure reducer 46. In addition, in the present case, the storage connection body 16 is provided with a fill level indicator 50 for displaying the volume currently contained in the pressure medium store 23.
Der in Fig. 5 dargestellte Geräteanschlusskörper 15 ermöglicht vermittels der Ventileinrichtung 29 sowohl einen gleichzeitigen Anschluss des Druckmittelspeichers 23 an den Druckanschluss 28 und einer stationären Druckluftquelle an den Druckanschluss 20, wobei durch den vermittels der Druckminderereinrichtung 46 vergleichsweise höher einstellbaren, durch den Druckmittelspeicher 23 bewirkten Ventildruck in diesem Fall eindeutig eine Druckversorgung der Treibkolbeneinheit 12 über den Druckmittelspeicher 23 definiert ist. Darüber hinaus ist es natürlich möglich, nur den Druckanschluss 20 oder den Druckanschluss 28 mit Druck zu beaufschlagen.By means of the valve device 29, the device connection body 15, shown in FIG. 5, permits simultaneous connection of the pressure medium reservoir 23 to the pressure port 28 and a stationary compressed air source to the pressure port 20, whereby the valve pressure comparatively higher, by the pressure medium reservoir 46, caused by the pressure medium reservoir 23 in this case, a pressure supply of the driving piston unit 12 is clearly defined via the accumulator 23. In addition, it is of course possible to pressurize only the pressure port 20 or the pressure port 28.
Wie insbesondere aus den Fig. 1 und 2 ersichtlich, ist der Druckmittelspeicher 23 mit seinem Anschlussende 51 so mit dem Druckanschluss 22 des Speicheranschlusskörpers 16 verbunden, dass er sich längs der Magazinvorrichtung 13 erstreckt. Dabei dient der Speicheranschlusskörper 16, der auf nicht näher dargestellte Art und Weise starr mit dem Magazingehäuse 19 der Magazinvorrichtung 13 verbunden ist, auch als Tragkonsole, die im Wesentlichen die mechanische Abstützung des Druckmittelspeichers 23 übernimmt. Ebenfalls am Magazingehäuse 19 angeordnet, befindet sich eine Protektoreinrichtung 52, die einen Auf- nahmering 53 aufweist, in den der Druckmittelspeicher 23 mit seinem Zylinderkörper 54 eingeführt ist. Je nach gewählter Passung zwischen dem Innendurchmesser des Aufnahmerings 53 und dem Außendurchmesser des Zylinderkörpers 54 kann der Aufnahmering 53 den Druckmittel- Speicher 23 ergänzend zum Speicheranschlusskörper 16 abstützen oder lediglich einen Schutzring um den Zylinderkörper 54 bilden, der den Druckmittelspeicher 23 vor Stößen, etwa verursacht durch ein Ablegen der Austreibvorrichtung 10 auf einer Ablagefläche schützt. Bei der in Figur 1 dargestellten Anordnung des Druckmittelspeichers 23 an der Magazinvorrichtung 13 kommt auch dem Magazingehäuse 19 eine ergänzende Protektorfunktion zu, da der Druckmittelspeicher 23 innerhalb der Breitenerstreckung des Magazingehäuses 19 angeordnet ist. As can be seen in particular from FIGS. 1 and 2, the pressure medium accumulator 23 is connected with its connection end 51 to the pressure connection 22 of the accumulator connection body 16 such that it extends along the accumulator device 13. In this case, the storage connection body 16, which is connected in a manner not shown rigidly with the magazine housing 19 of the magazine device 13, as a support bracket, which essentially takes over the mechanical support of the accumulator 23. Also arranged on the magazine housing 19, there is a protector device 52, which has a has receiving ring 53, in which the accumulator 23 is introduced with its cylinder body 54. Depending on the selected fit between the inner diameter of the receiving ring 53 and the outer diameter of the cylinder body 54 of the receiving ring 53 may support the pressure fluid accumulator 23 complementary to the storage port body 16 or merely form a guard ring to the cylinder body 54, the pressure fluid accumulator 23 from shocks, such as caused depositing the expulsion device 10 on a shelf protects. In the arrangement of the pressure medium reservoir 23 on the magazine device 13 shown in FIG. 1, the magazine housing 19 also has a complementary protector function, since the pressure medium reservoir 23 is arranged within the width extension of the magazine housing 19.
