Description

Spritzpistole spray gun
Die Erfindung betrifft eine Spritzpistole nach dem Oberbegriff des Anspruchs 1.The invention relates to a spray gun according to the preamble of claim 1.
Beim Arbeiten mit einer Spritzpistole ist es äußerst wichtig, den Spritzdruck derart einzustellen, daß sich eine optimale Zerstäubung für ein optimales Arbeitsergebnis bei guter Arbeitsgeschwindigkeit und hohem Auftragswirkungsgrad ergibt. Ein zu niedriger Spritzdruck kann z.B. zu Farbtonveränderungen im Basislack, zu einer Erhöhung der Orangenhautstruktur im Klarlack und Unilack und zu einer Reduzierung der Arbeitsgeschwindigkeit sowie eventuell der Strahlbreite fuhren. Auf der anderen Seite kann ein zu hoher Spritzdruck eine zu große Nernebelung des Spritzmaterials zu Folge haben und damit zu größeren Verlusten und unerwünschter Belastung der Arbeitsumgebung führen. Auch während des Spritzvorgangs sollte der zur Verfügung stehende Druck überwacht werden, um so z.B. einen möglichen Druckabfall durch zusätzliche Verbraucher im Druckluftleitungsnetz oder einen Druckanstieg durch Zuschalten von Ressourcen zu erkennen.When working with a spray gun, it is extremely important to set the spray pressure in such a way that optimum atomization results for an optimal work result with good working speed and high application efficiency. A spray pressure that is too low can e.g. lead to color changes in the base coat, to an increase in the structure of the orange peel in the clear coat and uni-coat and to a reduction in the working speed and possibly the jet width. On the other hand, too high a spray pressure can result in too much misting of the spray material and thus lead to greater losses and undesirable stress on the working environment. The available pressure should also be monitored during the spraying process, e.g. recognize a possible pressure drop due to additional consumers in the compressed air line network or a pressure increase due to the connection of resources.
Zur Einstellung und Überwachung des Spritzdrucks wird der Spritzpistole daher vielfach ein Druckregelventil mit Manometer vorgeschaltet. An dem Manometer kann der über einen Stellknopf am Druckregelventil einstellbare Druck abgelesen werden. Dieses am Lufteingang der Farbspritzpistole angeordnete Druckregelventil mit Manometer führt jedoch zu einer Verlängerung der Spritzpistole, wodurch deren Handlichkeit verschlechtert wird. Außerdem führt das Manometer bzw. das Druckregelventil infolge der inneren Umlenkungen zu einem Druckabfall. Darüber hinaus muß das in der Regel angeschraubte Druckregelventil zum Reinigen der Spritzpistole in Waschgeräten oder Reinigungsbecken abgebaut werden, da die Anzeigegenauigkeit des Manometers durch eindringendes Lösungsmittel oder Lack- bzw. Farbreste beeinträchtigt werden kann. Das Druckregelventil mit dem Manometer muß daher bei jedem Reinigungsvorgang abgeschraubt werden, was mit einem erheblichen Arbeitsaufwand verbunden ist.To adjust and monitor the spray pressure, the spray gun is therefore often preceded by a pressure control valve with a pressure gauge. The pressure that can be set using a control button on the pressure control valve can be read on the pressure gauge. However, this pressure regulating valve with a manometer arranged at the air inlet of the paint spray gun leads to an extension of the spray gun, as a result of which its handiness is impaired. In addition, the pressure gauge or pressure control valve leads to a drop in pressure as a result of the internal deflections. In addition, the pressure control valve, which is usually screwed on, must be dismantled for cleaning the spray gun in washing machines or cleaning basins, since the accuracy of the display of the pressure gauge can be impaired by penetrating solvent or paint or paint residues. The pressure control valve with the manometer must therefore be unscrewed during each cleaning process, which is associated with a considerable amount of work.
Es sind auch bereits Farbspritzpistolen bekannt, die an der Griffunterseite einen Anschluß zum Ankuppeln eines konventionellen Manometers aufweisen. Die üblicherweise verwendeten Manometer weisen als Druckaufhehmer in der Regel eine halbkreis- oder wendelförmig gebogene Stahlrohrfeder auf, deren durch den Druck bedingte Formänderung über einen Zeiger auf einem entsprechenden Ziffernblatt angezeigt wird. Die Stahlrohrfeder und die Anzeigeeinrichtung sind in einem gesonderten Gehäuse untergebracht. Auch bei dieser Ausführung wird jedoch die Handhabung der Spritzpistole durch das angekuppelte Manometer beeinträchtigt. Die Manometer müssen darüber hinaus zur Reinigung der Farbspritzpistole abnehmbar sein, so daß relativ aufwendige Kupplungs- oder Verbindungsysteme für den Anschluß des Manometers an die Spritzpistole erforderlich sind.Paint spray guns are also known which have a connection on the underside of the handle for coupling a conventional pressure gauge. The pressure gauges usually used as pressure transducers generally have a semicircular or helical bent tubular steel spring, the change in shape caused by the pressure is indicated by a pointer on a corresponding clock face. The tubular steel spring and the display device are housed in a separate housing. In this version, too, the handling of the spray gun is impaired by the coupled pressure gauge. The pressure gauges must also be removable for cleaning the paint spray gun, so that relatively complex coupling or connection systems are required for connecting the pressure gauge to the spray gun.
Es wurde auch bereits vorgeschlagen, an einer Seite des Pistolenkörpers ein konventionelles Manometer anzubringen. Auch eine derartige Spritzpistole weist durch das seitlich vorstehende Manometer eine schlechtere Handlichkeit auf. Außerdem muß eine solche Spritzpistole mit äußerster Sorgfalt behandelt werden, damit das seitlich angebrachte Manometer beim Ablegen der Spritzpistole nicht beschädigt wird.It has also been proposed to attach a conventional pressure gauge to one side of the gun body. Such a spray gun is also less manageable due to the laterally protruding manometer. In addition, such a spray gun must be handled with the utmost care so that the pressure gauge attached to the side is not damaged when the spray gun is put down.
Aufgabe der Erfindung ist es, eine handliche Spritzpistole mit einer gegen Verschmutzung unempfindlichen Druckmeßeinrichtung zu schaffen.The object of the invention is to provide a handy spray gun with a pressure measuring device which is insensitive to contamination.
Diese Aufgabe wird erfindungsgemäß durch eine Spritzpistole mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved according to the invention by a spray gun with the features of claim 1.
Bei der erfindungsgemäßen Spritzpistole ist im Pistolenkörper ein Druckaufhehmer der ebenfalls integrierten Druckmeßeinrichtung integriert. Dadurch wird eine sehr kompakte Bauweise mit einer geschützten Anordnung des Druckaufiiehmers im Inneren der Farbspritzpistole ermöglicht. Der Druckaufhehmer steht darüber hinaus über eine Kapillare mit einem Druckluftzuful rkanal in Verbindung. Durch diese Kapillare kann verhindert werden, daß die zur Reinigung der Spritzpistole verwendeten Lösemittel, Lack- oder Farbreste in den Bereich des Druckaufiiehmers gelangen und damit eine ordnungsgemäße Druckmessung beeinträchtigen oder verhindern. Die erfindungsgemäße Farbspritzpistole kann so ohne Demontage der Meßeinrichtung gereinigt werden, wobei keine Gefahr für den im allgemeinen empfindlichen Druckaufhehmer besteht.In the spray gun according to the invention, a pressure transducer of the pressure measuring device, which is also integrated, is integrated in the gun body. This enables a very compact design with a protected arrangement of the pressure sensor inside the paint spray gun. The pressure transducer is also connected to a compressed air supply duct via a capillary. This capillary can prevent the solvents, paint or paint residues used to clean the spray gun from getting into the area of the pressure transducer and thus impairing or preventing proper pressure measurement. The paint spray gun according to the invention can thus be cleaned without dismantling the measuring device, there being no danger for the generally sensitive pressure transducer.
Vorteilhafte Ausführungsformen und zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. So ist in einer besonders zweckmäßigen Ausführung auch die Anzeigeeinrichtung und eine eventuelle Schaltungsanordnung zur Signalwandlung und -auswertung z.B. in den Handgriff der Spritzpistole integriert. Dadurch ist die gesamte Meßeinrichtung innerhalb des Pistolenkörpers untergebracht und dort vor Beschädigungen optimal geschützt.Advantageous embodiments and expedient developments of the invention are specified in the subclaims. Thus, in a particularly expedient embodiment, the display device and any circuitry for signal conversion and evaluation, for example, is integrated in the handle of the spray gun. As a result, the entire measuring device is housed within the gun body and optimally protected there from damage.
Die als Analog- oder Digitalanzeige ausführbare Anzeigeeinrichtung kann aber auf einem hinteren Endteil des Pistolenköpers derart angeordnet sein, daß das Anzeigefeld von hinten ablesbar ist. Dadurch ergibt sich der Vorteil, daß die Druckanzeige beim Spritzen immer im Blickfeld ist.However, the display device, which can be designed as an analog or digital display, can be arranged on a rear end part of the gun body in such a way that the display field can be read from the rear. This has the advantage that the pressure display is always in view when spraying.
In einer möglichen Ausführungsform kann die Kapillare in einem Verbindungskanal angeordnet sein, der zwischen einem Druckerfassungsraum und dem Luftzufuhrkanal im Bereich des Pistoleneingangs stromaufwärts einer Ventilanordnung verläuft. In dieser Ausführung kann der Pistoleneingangsdruck erfaßt werden. Die Kapillare kann aber auch in einem Verbindungskanal zwischen dem Druckerfassungsraum und einem stromabwärts der Ventileinrichtung gelegenen Teil angeordnet sein. Dadurch kann der über eine Stelleinrichtung an der Ventilanordnung eingestellte Luftdruck, der zum Spritzen zur Verfügung steht, erfaßt und angezeigt werden.In one possible embodiment, the capillary can be arranged in a connecting channel which runs between a pressure detection chamber and the air supply channel in the region of the gun inlet upstream of a valve arrangement. In this version, the gun inlet pressure can be detected. However, the capillary can also be arranged in a connecting channel between the pressure detection space and a part located downstream of the valve device. As a result, the air pressure which is set via a control device on the valve arrangement and is available for spraying can be detected and displayed.

Die in Fig. 1 dargestellte Spritzpistole enthält einen Pistolenkörper 1 mit einem Handgriff 2 und einem Oberteil 3, an dem ein Aufhängehaken 4 angeformt ist. Durch das Oberteil 3 verläuft eine von vorne nach hinten durchgehende und mehrfach abgestufte Durchgangsbohrung 5, in der eine Düsennadel 6 axial verschiebbar geführt ist. Die Durchgangsbohrung 5 bildet in einem vorderen Bereich einen erweiterten Aufhahmeraum 7, in den eine schräge Zulaufbohrung 8 zum Aufsatz eines nicht dargestellten Farbaufiiahmebehälters mündet. An dem vorderen Ende der Durchgangsbohrung 5 ist eine Düsenanordnung 9 montiert, die eine mittels eines Gewindes am Oberteil 3 des Pistolenkörpers 1 fixierbare Farbdüse 10 enthält. Die Farbdüse 10 weist an ihrem vorderen Ende eine Düsenbohrung 11 auf, die zusammen mit einem spitz zulaufenden vorderen Endteil der über einen Betätigungshebel 12 axial bewegbaren Düsennadel 6 einen regulierbaren Zulauf für die Farbe, den Lack oder dgl. bildet. Der Betätigungshebel 12 ist derart mit der Düsennadel 6 verbunden, daß diese beim Zurückziehen des Betätigungshebels 12 entgegen der Kraft einer Feder 13 nach hinten verschoben wird und die Düsenbohrung 11 zur Abgabe der Farbe öffnet. Über eine am hinteren Ende der Durchgangsbohrung 5 angeordnete Stellschraube 14 mit entsprechender Kontermutter 15 sind die Vorspannung der Druckfeder 13 und der Hub der Düsennadel 6 einstellbar. Durch den Betätigungshebel 12 ist über eine Stange 16 außerdem eine in Fig. 4 erkennbare Ventilanordnung 17 mit einer hinteren Stelleinrichtung 18 zur Steuerung der Druckluftzufuhr zur Düsenanordnung 9 betätigbar. Über einen stromaufwärts der Ventilanordnung 17 liegenden Teil 19 und einen - in Fig. 4 gezeigten - stromabwärts der Ventilanordnung 17 liegenden Teil 20 eines Druckluftzufuhrkanals im Pistolengehäuse 1 wird die Druckluft zu einem Luftleitsystem 21 und von dort zu einem Ringspalt 22 geleitet, der die Düsenbohrung 11 umgibt. Die Druckluft erzeugt im Bereich der Düsenbohrung 11 ein Vakuum, durch das die Farbe aus der Düsenbohrung 11 gesaugt und mit der Druckluft unter Bildung eines Rundstrahls mitgerissen wird. Über sogenannte Hornluftbohrungen 23 in vorstehenden Hörnern 24 einer die Farbdüse 10 umgebenden Luftkappe 25 kann außerdem die Druckluft zur Formung des Rundstrahls in einen Flachstrahl austreten. Die Luftkappe 25 ist über eine Überwurfmutter 26 an dem Oberteil 3 des Gehäuses 1 befestigbar.The spray gun shown in Fig. 1 contains a gun body 1 with a handle 2 and an upper part 3, on which a suspension hook 4 is formed. Through the upper part 3 a through hole 5 runs continuously from front to back and in which a nozzle needle 6 is guided axially displaceably. In a front area, the through bore 5 forms an enlarged receiving space 7, into which an oblique inlet bore 8 opens for the attachment of an ink reservoir, not shown. At the front end of the through bore 5, a nozzle arrangement 9 is mounted, which contains a paint nozzle 10 which can be fixed by means of a thread on the upper part 3 of the gun body 1. The paint nozzle 10 has at its front end a nozzle bore 11 which, together with a tapering front end part of the nozzle needle 6, which can be moved axially via an actuating lever 12, forms an adjustable inlet for the paint, the lacquer or the like. The actuating lever 12 is connected to the nozzle needle 6 in such a way that when the actuating lever 12 is pulled back, it is displaced backwards against the force of a spring 13 and the nozzle bore 11 opens to deliver the paint. The preload of the compression spring 13 and the stroke of the nozzle needle 6 can be adjusted via an adjusting screw 14 arranged at the rear end of the through bore 5 with a corresponding lock nut 15. A valve arrangement 17 which can be seen in FIG. 4 and has a rear actuating device 18 for controlling the compressed air supply to the nozzle arrangement 9 can also be actuated by the actuating lever 12 via a rod 16. Via a part 19 lying upstream of the valve arrangement 17 and a part 20 - shown in FIG. 4 - of a compressed air supply channel in the gun housing 1 lying downstream of the valve arrangement 17, the compressed air is conducted to an air guide system 21 and from there to an annular gap 22 which defines the nozzle bore 11 surrounds. The compressed air creates a vacuum in the area of the nozzle bore 11, through which the paint is sucked out of the nozzle bore 11 and entrained with the compressed air to form a round jet. The so-called horn air bores 23 in protruding horns 24 of an air cap 25 surrounding the paint nozzle 10 can also release the compressed air for shaping the round jet into a flat jet. The air cap 25 can be fastened to the upper part 3 of the housing 1 via a union nut 26.
Die Düsenanordnung 9 und deren Aufbau ist als solches bereits bekannt. Eine mögliche Düsenanordnung ist z.B. in der EP 0710 506 AI offenbart. Zu weiteren Einzelheiten bezüglich der Düsenanordnung wird daher auf diese Druckschrift verwiesen, deren Offenbarungsgehalt zum Gegenstand dieser Anmeldung gemacht wird.The nozzle arrangement 9 and its structure is already known as such. A possible nozzle arrangement is e.g. disclosed in EP 0710 506 AI. For further details regarding the nozzle arrangement, reference is therefore made to this publication, the disclosure content of which is the subject of this application.
Die Spritzpistole enthält eine in den Handgriff 2 des Pistolenkörpers 1 integrierte Drackmeßeinrichtung 27, die im wesentlichen aus einem Druckaufhehmer 28, einer Schaltungsanordnung 29 und einer Anzeigeeinrichtung 30 besteht. Wie aus Fig. 2 hervorgeht, ist der z.B. als piezoelektrischer Drucksensor ausgeführte Druckaufhehmer 28 in eine seitlich im Handgriff 2 vorgesehene Sacklochbohrung 31 eingesetzt, die mit einer oberen Meßfläche 32 einen Druckerfassungsraum 33 begrenzt. Der Druckaufhehmer 28 ist über elektrische Anschlüsse 34 mit der Schaltungsanordnung 29 verbunden, die im wesentlichen aus einer in einem entsprechenden Aufhahmeraum 35 im Pistolengriff 2 angeordneten Platine mit der entsprechenden Schaltung besteht. Über der Schaltungsanordnung 29 ist die z.B. als LCD- Anzeige ausgeführte Anzeigeeinrichtung 30 für die Anzeige des durch den Druckaufhehmer 28 erfaßten Drucks angeordnet. Die Schaltungsanordnung 29 und die Anzeigeeinrichtung 30 werden über ein Zwischenelement 36 durch eine mit einem Sichtfenster 37 versehene Abdeckplatte 38 im Pistolengriff 2 gehalten. Die mit der Seitenfläche des Pistolengriffs 2 abschließende Abdeckplatte 38 ist zur Verhinderung eines Flüssigkeits- und Schmutzeintritts durch Dichtelemente 39 abgedichtet mit dem Pistolengriff 2 verschraubt. Auf der zur Anzeigeeinrichtung 30 entgegengesetzten Seite des Handgriffs 2 ist ein durch einen Deckel 40 verschließbares Aufhahmefach 41 für eine Batterie 42 zur elektrischen Versorgung der Auswerteschaltung und Anzeigeeinrichtung vorgesehen. Wie besonders aus Fig. 3 hervorgeht, ist der Druckerfassungsraum 33 durch einen mit einer Kapillare 43 versehenen Verbindungskanal 44 mit dem stromaufwärts der Ventilanordnung gelegenen Teil 19 des Druckluftzufül rkanals im Bereich des Pistolenemtritts verbunden. Die Kapillare ist als Bohrung mit einem Durchmesser von 0,5 bis 1,8 mm ausgeführt. Bei dieser Ausführung ist der Verbindungskanal 44 in Form einer mittels einer Kugel 45 nach außen verschlossenen seitlichen Verbindungsbohrung ausgeführt. Durch die Kapillare 43 kann verhindert werden, daß ein bei der Reinigung der Spritzpistole verwendetes Reinigungs- bzw. Lösungsmittel und evtl. gelöste Lackpartikel in den Druckerfassungsraum gelangen und dort zu einer Beeinträchtigung der Meßgenauigkeit führen oder sogar eine Messung verhindern.The spray gun contains a pressure measuring device 27 integrated in the handle 2 of the gun body 1, which essentially consists of a pressure transducer 28, a circuit arrangement 29 and a display device 30. As can be seen from FIG. 2, the pressure transducer 28, which is designed, for example, as a piezoelectric pressure sensor, is inserted into a blind hole 31 provided laterally in the handle 2, which delimits a pressure detection space 33 with an upper measuring surface 32. The pressure transducer 28 is connected via electrical connections 34 to the circuit arrangement 29, which essentially consists of a circuit board with the corresponding circuit arranged in a corresponding receiving space 35 in the pistol grip 2. Arranged above the circuit arrangement 29 is the display device 30, for example in the form of an LCD display, for displaying the pressure detected by the pressure transducer 28. The circuit arrangement 29 and the display device 30 are held in the pistol grip 2 via an intermediate element 36 by a cover plate 38 provided with a viewing window 37. The cover plate 38, which closes with the side surface of the pistol grip 2, is screwed to the pistol grip 2 in a sealed manner to prevent liquid and dirt from entering by sealing elements 39. On the side of the handle 2 opposite to the display device 30, a receiving compartment 41, which can be closed by a cover 40, is provided for a battery 42 for the electrical supply of the evaluation circuit and display device. As can be seen particularly from FIG. 3, the pressure detection chamber 33 is connected by a connection channel 44 provided with a capillary 43 to the part 19 of the compressed air supply channel located upstream of the valve arrangement in the region of the gun outlet. The capillary is designed as a bore with a diameter of 0.5 to 1.8 mm. In this embodiment, the connecting channel 44 is designed in the form of a lateral connecting bore which is closed to the outside by means of a ball 45. The capillary 43 can prevent a cleaning agent or solvent used in the cleaning of the spray gun and possibly dissolved paint particles from reaching the pressure detection space and there impairing the measuring accuracy or even preventing a measurement.
Die in den Fig. 4 bis 6 dargestellte Ausführung unterscheidet sich von der vorstehend beschriebenen Ausführung dadurch, daß die Kapillare 43 in einem Verbindungskanal 46 angeordnet ist, der zwischen dem Druckerfassungsraum 33 und einem stromabwärts der Ventilanordnung 17 angeordneten Teil 20 des Druckluftzufuhrkanals liegt. Dadurch kann der durch die Stelleinrichtung 18 eingestellte und für das Spritzen zur Verfügung stehende Luftdruck erfaßt und angezeigt werden. In Fig. 5 ist eine weitere EinStelleinrichtung 47 mit einem seitlichen Drehknopf 48 zur Regulierung der Druckluftzufuhr zu den Bohrungen 23 gezeigt. Der weitere Aufbau der Spritzpistole entspricht der in den Fig. 1 bis 3 gezeigten Ausführung.The embodiment shown in FIGS. 4 to 6 differs from the embodiment described above in that the capillary 43 is arranged in a connecting channel 46 which lies between the pressure detection chamber 33 and a part 20 of the compressed air supply channel arranged downstream of the valve arrangement 17. As a result, the air pressure set by the adjusting device 18 and available for spraying can be detected and displayed. 5 shows a further adjusting device 47 with a lateral rotary knob 48 for regulating the compressed air supply to the bores 23. The further structure of the spray gun corresponds to the embodiment shown in FIGS. 1 to 3.
Bei der in den Fig. 7 bis 9 gezeigten Ausführung ist der Druckaufhehmer 28 in einer gesonderten Aufiiahmekammer 49 oberhalb der Schaltungsanordnung 29, der Anzeigeeinrichtung 30 und des Aufiiahmefachs 41 fiir die Batterie 42 angeordnet. Ansonsten ist die Spritzpistole im wesentlichen wie bei dem zuvor beschriebenen Ausführungsbeispiel gemäß der Fig. 4 bis 6 aufgebaut. Auch bei dieser Ausführung kann der durch die Stelleinrichtung 18 eingestellte Arbeitsdruck erfaßt und angezeigt werden.In the embodiment shown in FIGS. 7 to 9, the pressure receiver 28 is arranged in a separate receiving chamber 49 above the circuit arrangement 29, the display device 30 and the receiving compartment 41 for the battery 42. Otherwise, the spray gun is constructed essentially as in the previously described embodiment according to FIGS. 4 to 6. In this embodiment, too, the working pressure set by the adjusting device 18 can be detected and displayed.
In den Fig. 10 und 11 ist ein weiteres Ausführungsbeispiel gezeigt. Bei dieser Ausführung weist der Pistolenkörper 1 ein hinteres Endstück 50 auf, das entweder einstückig mit dem Oberteil 3 oder als z.B. einschraubbares bzw. einsteckbares Endteil ausgeführt sein kann. In dem Endstück 50 ist eine Aufiiahmekammer 51 mit einem Druckerfassungsraum 52 für den Druckaufhehmer 28 vorgesehen. Der Druckerfassungsraum 52 ist über eine in Achsrichtung des Endteils angeordnete Kapillare 53 mit dem Drackluftzuführkanal stromaufwärts der Ventilanordnung 17 verbunden. An dem Endstück 50 ist eine digitale Anzeigeeinrichtung 54 mit einem Anzeigefeld 55 derart angeordnet, daß sie beim Arbeiten mit der Spritzpistole von hinten sichtbar ist. Der Druck kann somit während des Spritzens ständig überwacht werden.A further embodiment is shown in FIGS. 10 and 11. In this embodiment, the gun body 1 has a rear end piece 50, which can either be made in one piece with the upper part 3 or as an end part that can be screwed in or inserted, for example. In the end piece 50 a Aufiiahmekammer 51 is provided with a pressure detection space 52 for the pressure transducer 28. The pressure detection chamber 52 is upstream of the capillary 53, which is arranged in the axial direction of the end part, with the compressed air supply channel Valve arrangement 17 connected. At the end piece 50, a digital display device 54 with a display field 55 is arranged such that it is visible from behind when working with the spray gun. The pressure can thus be monitored continuously during spraying.
Die Erfindung ist nicht auf die vorstehend beschriebenen und in der Zeichnung dargestellten Ausführungsbeispiele beschränkt. So können z.B. anstelle piezoelektrischer Druckaufhehmer auch andere geeignete Druckaufiiel mer bzw. Drucksensoren verwendet werden. Darüber hinaus können die Druckaufhehmer auch an anderen geeigneten Stellen des Pistolenkörpers angebracht sein. The invention is not limited to the exemplary embodiments described above and shown in the drawing. For example, Instead of piezoelectric pressure transducers, other suitable pressure transducers or pressure sensors can also be used. In addition, the pressure transducers can also be attached to other suitable locations on the gun body.
