Description

Beschreibung description
Austragkopf für Medien-AustraσvorrichtungenDischarge head for media discharge devices
Die Erfindung betrifft einen Austragkopf, wie er z.B. als Betätigungshandhabe und/oder Austragstutzen an handbetätigba- ren Austragvorrichtungen für fließfähige Medien, wie flüssige, pastöse oder ähnliche Medien verwendet wird.The invention relates to a discharge head, as e.g. is used as an actuating handle and / or discharge nozzle on hand-operated discharge devices for flowable media, such as liquid, pasty or similar media.
Der Austragkopf kann als in sich geschlossene Baugruppe nach¬ träglich an der fertiggestellten, einen Ventilstößel oder einen Pumpkolbenschaft aufweisenden Austragvorrichtung z.B. lediglich mit einer Steckverbindung dadurch befestigt werden, daß ein Schaftende eines Schaftes des Austragkopfes auf den Ventil¬ stößel bzw. den Pumpkolbenschaft aufgesteckt wird.The discharge head can be retrofitted as a self-contained assembly on the finished discharge device, which has a valve tappet or a pump piston shaft, e.g. can only be fastened with a plug connection in that a shaft end of a shaft of the discharge head is pushed onto the valve tappet or the pump piston shaft.
Ist der Schaft einteilig mit dem Grundkörper ausgebildet, so kann ein und derselbe Austragkopf-Grundkörper nur mit einer be- stimmten Größe von Stößeln verbunden werden. Ähnlich verhält es sich, wenn der Pumpkolben eine Montageeinheit mit dem Austrag¬ kopf bildet.If the shaft is formed in one piece with the base body, one and the same discharge head base body can only be certain size of pestle to be connected. The situation is similar when the pump piston forms an assembly unit with the discharge head.
Der Erfindung liegt des weiteren die Aufgabe zugrunde, Nach¬ teile bekannter Ausbildungen zu vermeiden und insbesondere einen Austragkopf zu schaffen, der bei einfacher Ausbildung an unterschiedliche Austragvorrichtungen sowie gegebenenfalls an unterschiedliche Austragöffnungen angepaßt werden kann.The invention is further based on the object of avoiding disadvantages of known designs and, in particular, of creating a discharge head which can be adapted to different discharge devices and, if appropriate, to different discharge openings with a simple design.
Gemäß der Erfindung kann ein gesonderter Schaft durch eine Steckverbindung, insbesondere ausschließlich durch Preßsitz, an dem Austragkopf befestigt sein, wobei dieser Schaft vorzugs¬ weise mit einem Ende ein Verbindungsglied zur unmittelbaren Verbindung mit dem Betätigungsglied der Austragvorrichtung und/oder mit dem anderen Ende ein profiliertes Schaftende bildet, das z.B. der Führung des Medienstromes in wechselnden Richtungen dient. Bevorzugt ist dieses Schaftende in eine kurze, frei vorstehende Innenhülse des Austragkopfes so ein¬ gesetzt, daß der größte Teil der Länge des Schaftes voll¬ ständig berührungsfrei innerhalb des Austragkopfes liegt.According to the invention, a separate shaft can be fastened to the discharge head by means of a plug-in connection, in particular exclusively by a press fit, this shaft preferably having a connecting member with one end for direct connection to the actuating member of the discharge device and / or with the other end a profiled Shaft end forms, for example serves to guide the media flow in changing directions. This end of the shaft is preferably inserted into a short, freely projecting inner sleeve of the discharge head in such a way that the major part of the length of the shaft lies completely contact-free within the discharge head.
Der Schaft bzw. das festsitzend im Austragkopf angeordnete Schaftende weist zweckmäßig in Längsrichtung aneinander- schließende Schaftabschnitte unterschiedlicher Außenweite auf, wobei er zweckmäßig im Bereich des Verbindungsgliedes die größte und am anderen Schaftende die kleinste Schaftweite hat. Das Verbindungsglied weist nach Art einer Hülse bzw. Muffe eine zentrale Stecköffnung für die Aufnahme des Betätigungsgliedes der Austragvorrichtung auf.The shaft or the shaft end which is fixedly arranged in the discharge head expediently has longitudinally adjoining shaft sections of different outer width, where it expediently has the largest shaft width in the region of the connecting member and the smallest shaft width at the other shaft end. The connecting member has, in the manner of a sleeve or sleeve, a central plug-in opening for receiving the actuating member of the discharge device.
Im wesentlichen unabhängig von dieser Ausbildung des Austrag¬ kopfes kann es auch vorteilhaft sein, wenn das der Austrag- Öffnung zugehörige Ende des Schaftes einen reduzierten Dü¬ senkern mit einer Stirn- bzw. Endwand bildet, axial benachbart zu welcher der Düsenkern am Umfang von mindestens einer Durch¬ trittsöffnung durchsetzt ist, welche einen vollständig inner¬ halb des Schaftes liegenden Abschnitt des Auslaßkanales mit einem am Außenumfang des Schaftes liegenden Abschnitt ver¬ bindet. Die Endwand, die nach Art einer U-förmigen Brücke über zwei Schenkel mit dem übrigen Schaft einteilig verbunden sein kann, kann an ihrer Endfläche, z.B. zur Bildung einer Drallein¬ richtung, auch Nuten, Vertiefungen o.dgl. aufweisen und mit dieser Endfläche an einer im wesentlichen ununterbrochen durch¬ gehenden inneren Stirnfläche des Austragkopfes anliegen, welch von einem die Austragöffnung bildenden Düsenkanal durchsetzt ist. Dadurch kann lediglich durch Verwendung eines anderen Schaftes die Strömungsbeeinflussung des Mediums vor Eintritt i den Düsenkanal verändert werden.Regardless of this configuration of the discharge head, it can also be advantageous if the discharge Opening associated end of the shaft forms a reduced nozzle core with an end or end wall, axially adjacent to which the nozzle core is penetrated on the circumference by at least one passage opening, which has a section of the outlet channel lying completely inside the shaft section lying on the outer circumference of the shaft. The end wall, which can be connected in one piece to the rest of the shaft in the manner of a U-shaped bridge via two legs, can also have grooves, depressions or the like on its end face, for example to form a swirl device. have and with this end face against an essentially continuous inner end face of the discharge head, which is penetrated by a nozzle channel forming the discharge opening. As a result, the flow influencing of the medium before entering the nozzle channel can only be changed by using a different shaft.
Der innerhalb des Schaftes liegende Abschnitt des Auslaßkana¬ les weist zweckmäßig wenigstens auf einem an den Querkanal anschließenden Teil seiner Länge oder auf seiner ganzen Länge Querschnitte auf, die von der Kreisform abweichen, z.B. annä¬ hernd flach rechteckig oder derart sternförmig sind, daß z.B. drei um eine Mittelachse gleichmäßig verteilte, flache Nut¬ querschnitte mit ihren der Mittelachse zugekehrten, offenen Längsseiten aneinanderschließen.The section of the outlet channel located within the shaft expediently has cross sections which deviate from the circular shape, e.g. at least on part of its length or over its entire length, adjoining the transverse channel, e.g. are approximately flat rectangular or so star-shaped that e.g. Connect three flat groove cross sections evenly distributed around a central axis with their open long sides facing the central axis.

The piston unit 4 forms an outlet valve 8 for a pump outlet channel penetrating it inside up to an actuating shaft 9. The actuating shaft 9 serves as the only connection of the discharge device 2 to the discharge head 1 lying in the central axis 10 of the pump 3 by means of an axial clamping or plug connection.
Der durch zwei Kunststoff-Spritzteile gebildete Austragkopf 1 weist einen äußeren, vollständig freiliegenden, gehäuseartig hohlen Grundkörper 11 und einen vollständig versenkt in diesem liegenden, rohrartig an beiden Enden offenen einteiligen Schaft 12 auf, der nur im Bereich eines kurzen Endes in unmittel¬ barer, vollständig ummantelter Berührung mit dem Grundkörper 11 steht. Der Grundkörper 11 bildet an einem Ende eine flache, erweiterte Kappe 13, in welche im zusammengesetzten Zustand das vorstehende Ende des Gehäuses 5 bzw. der Zylinderdeckel hinein¬ ragt. Die geschlossene Stirnwand dieser Kappe 13 bildet eine Druck-Handhabe 14 zur Betätigung der Pumpe 3.The discharge head 1, which is formed by two injection molded plastic parts, has an outer, completely exposed, hollow housing-like base body 11 and a one-piece shaft 12, which is completely recessed therein and is open at both ends in a tube-like manner. completely covered contact with the base body 11. The base body 11 forms at one end a flat, expanded cap 13, into which the protruding end of the housing 5 or the cylinder cover protrudes when assembled. The closed end wall of this cap 13 forms a pressure handle 14 for actuating the pump 3.
Über die Stirnwand steht ein gegenüber der Kappe 13 wesentlich reduzierter Austragstutzen 15 frei vor, der durch eine mit einem Ende einteilig an die Stirnwand anschließende Außenhülse 16 und eine nur über einen kleinen Teil von deren Länge reichende Innenhülse 17 gebildet ist. Die Innenhülse 17 geht mit ihrem von der Kappe 13 abgekehrten Ende einteilig in das zugehörige Ende der Außenhülse 16 über und bildet mit dieser eine Düsenkappe 18. Der Außenumfang der frei gegen die Kappe 13 vorstehenden Innenhülse 17 ist im wesentlichen über deren gesamte Länge gegenüber dem Innenumfang der Außenhülse 16 berührungsfrei. Die Stirnwand der Düsenkappe 18 ist am Ende des Austragstutzens 15 von einem Düsenkanal einer Zerstäuberdüse durchsetzt, die die Austragöffnung 19 der Austragvorrichtung 2 bildet.A discharge nozzle 15, which is substantially reduced compared to the cap 13, protrudes freely above the end wall, which is formed by an outer sleeve 16 which integrally connects the end wall with one end and an inner sleeve 17 which only extends over a small part of its length. The inner sleeve 17 merges with its end facing away from the cap 13 in one piece into the associated end of the outer sleeve 16 and forms with it a nozzle cap 18. The outer circumference of the inner sleeve 17 projecting freely against the cap 13 is essentially contact-free over its entire length with respect to the inner circumference of the outer sleeve 16. At the end of the discharge nozzle 15, the end wall of the nozzle cap 18 is penetrated by a nozzle channel of an atomizing nozzle which forms the discharge opening 19 of the discharge device 2.
Der Schaft 12 ist mit einem in der Außenweite mehrfach abge¬ setzten Schaftende 20, das nur etwa einem Viertel der Gesamt¬ länge des Schaftes 12 entspricht, fest sitzend in die Innen¬ hülse 17 und die Düsenkappe eingepreßt und ausschließlich dadurch befestigt. Es ist denkbar, am Innenumfang der Außen¬ hülse 16 Stützrippen o.dgl. vorzusehen, welche den Schaft 12 im Abstand von der Innenhülse 17 am Außenumfang in seiner Lage sichern. Das Schaftende 20 bildet als zugehörigen Endabschnitt des Schaftes 12 einen in eine Bohrung der Düsenkappe 18 eng anliegend eingreifenden Düsenkern 21, der die kleinste Außen¬ weite aller Schaftabschnitte hat und bis an das innere Ende des Düsenkanales bzw. die dieses ringförmig umgebende, annähernd ebene Bodenfläche der Bohrung reicht.The shaft 12 is firmly seated into the inner sleeve 17 and the nozzle cap with a shaft end 20 which is offset several times in the outer width and corresponds to only about a quarter of the total length of the shaft 12, and is only fastened thereby. It is conceivable for 16 support ribs or the like on the inner circumference of the outer sleeve. to provide which secure the shaft 12 in position at a distance from the inner sleeve 17 on the outer circumference. The shaft end 20, as the associated end section of the shaft 12, forms a nozzle core 21 which engages closely in a bore of the nozzle cap 18 and which has the smallest outer width of all shaft sections and up to the inner end of the nozzle channel or the approximately flat bottom surface surrounding it in a ring the hole is enough.
Im Bereich des Überganges zwischen der Außen- und Innenhülse 16, 17 geht der Düsenkern 21 über eine annähernd ebene Ring¬ schulter 36 in einen kurzen, spitzwinklig konischen Schaftab¬ schnitt 22 über, an den wiederum ein im wesentlichen zylind¬ rischer Schaf abschnitt 23 kontinuierlich anschließt. Dieser Schaftabschnitt 23 geht innerhalb der Innenhülse 17 in einen weiteren, spitzwinklig konischen und über das freie Ende der Innenhülse 17 hinausreichenden Schaftabschnitt 24 kontinuier¬ lich über, an den ein längster, durchgehend zylindrischer Schaftabschnitt 25 kontinuierlich anschließt. Der Schaftab¬ schnitt 25 ist von einer seinen Außenumfang anliegend umge- benden, geschlossenen Ummantelung frei und geht an dem vom Schaftende 20 abgekehrten Ende in ein erweitertes, hülsenför- miges Verbindungsglied 26 über, das gegenüber der Stirnwand berührungsfrei bis in die Kappe 13 hineinragt, jedoch gegen¬ über der offenen Kappenseite zurückversetzt ist. Das Verbin¬ dungsglied 26 bildet mit seinem Innenumfang eine am Boden von einer Ringschulter begrenzte Stecköffnung 27, die an den Be¬ tätigungsschaft 9 so angepaßt ist, daß dieser bis zum Anschlag seines Endes an der Ringschulter eingesetzt werden kann. Die Stecköffnung 27 kann am Einführende trichterförmig erweitert sein und zwischen ihren Enden mindestens einen vorstehenden Ringwulst als Abdichtung und Klemmzone für den Betätigungs¬ schaft 9 aufweisen.In the area of the transition between the outer and inner sleeves 16, 17, the nozzle core 21 merges via an approximately flat annular shoulder 36 into a short, acute-angled conical shaft section 22, to which in turn an essentially cylindrical sheep section 23 continuously connects. This shaft section 23 merges within the inner sleeve 17 into a further, conical angle and beyond the free end of the inner sleeve 17 extending shaft section 24, to which a longest, continuously cylindrical shaft section 25 is continuously connected. The shaft section 25 is surrounded by an outer circumference free, closed sheathing and at the end facing away from the shaft end 20 merges into an expanded, sleeve-shaped connecting member 26, which projects into the cap 13 without contact with respect to the end wall, but is set back relative to the open cap side. With its inner circumference, the connecting member 26 forms a plug opening 27 which is delimited on the bottom by an annular shoulder and which is adapted to the actuating shaft 9 in such a way that it can be used up to the stop of its end on the annular shoulder. The insertion opening 27 can be funnel-shaped at the introducer and have at least one projecting annular bead between its ends as a seal and clamping zone for the actuating shaft 9.
Der Schaft 12 bildet einen Abschnitt 29 eines unmittelbar an den Pumpen-Auslaßkanal des Betätigungsschaftes 9 durch die genannte Steckverbindung anzuschließenden Auslaßkanales 28. Der Abschnitt 29 reicht von dem Verbindungsglied 26 bis zum Düsen¬ kern 21 bzw. zur Ringschulter 36 und ist bohrungsartig aus¬ schließlich vom Mantel des Schaftes 12 begrenzt, sowie von eingesetzten Teilen frei. Im Bereich der Ringschulter 36 geht der Auslaßkanal 28 in einen den Schaft 12 diametral durchset¬ zenden und ebenfalls über seine Länge im wesentlichen kon¬ stante Querschnitte aufweisenden Querkanal 31 über, der etwa gleiche Durchflußquerschnitte wie der Abschnitt 29 hat. Der Querkanal 31 durchsetzt den Außenumfang des Schaftes 12 nur im Bereich des Düsenkernes 21 mit zwei voneinander abgekehrten Durchtrittsöffnungen 33, die gleich weit wie der Querkanal 31 sind und an die Ringschulter 36 anschließen.The shaft 12 forms a section 29 of an outlet channel 28 to be connected directly to the pump outlet channel of the actuating shaft 9 by means of the plug connection mentioned. The section 29 extends from the connecting member 26 to the nozzle core 21 or to the annular shoulder 36 and is exclusive of bores limited by the shell of the shaft 12, as well as free of inserted parts. In the area of the annular shoulder 36, the outlet channel 28 merges into a transverse channel 31 which penetrates the shaft 12 diametrically and also has essentially constant cross sections over its length and which has approximately the same flow cross sections as the section 29. The transverse channel 31 passes through the outer circumference of the shaft 12 only in the region of the nozzle core 21 with two through openings 33 facing away from one another, which are the same width as the transverse channel 31 and connect to the annular shoulder 36.
Der Düsenkern 21 bildet dadurch eine im Abstand der Ring¬ schulter 36 gegenüberliegende Endwand 34, deren Innenseite 35 den Querkanal 31 begrenzt und die über zwei einander gegen- überliegende, den Querkanal 31 und die Durchtrittsöffnungen 33 seitlich begrenzenden Schenkel 38 mit dem Schaftabschnitt 22 bzw. der Ringschulter 36 einteilig verbunden ist. Von der Ringschulter 36 reichen bis zur Endfläche 39 des Schaftes 12 bzw. zur Außenseite der Endwand 34 Längskanäle 32, von denen jeder eine Durchtrittsöffnung 33 mit einer gemeinsamen, un¬ mittelbar benachbart zum inneren Ende des Düsenkanales lie¬ genden Dralleinrichtung 37 verbindet. Jeder Längskanal 32 ist durch eine Axialnut gebildet, deren Bodenfläche zweckmäßig um die Mittelachse 10 gekrümmt ist und die gleich breit wie oder breiter als die zugehörige Durchtrittsöffnung 33 sein kann, wobei ihre Durchflußquerschnitte über ihre Länge zweckmäßig konstant sind. Die Nuten sind im Außenumfang des Düsenkernes 21 vorgesehen und durch den zugehörigen Innenumfang der Düsen¬ kappe 18 an den offenen Nut-LängsSeiten verschlossen.The nozzle core 21 thereby forms an end wall 34 opposite one another at a distance from the annular shoulder 36, the inside 35 of which delimits the transverse channel 31 and which is opposed by two Overlying leg 38, which laterally delimits the transverse channel 31 and the passage openings 33, is connected in one piece to the shaft section 22 or the annular shoulder 36. Longitudinal channels 32 extend from the annular shoulder 36 to the end face 39 of the shaft 12 or to the outside of the end wall 34, each of which connects a passage opening 33 to a common swirl device 37 lying immediately adjacent to the inner end of the nozzle channel. Each longitudinal channel 32 is formed by an axial groove, the bottom surface of which is expediently curved about the central axis 10 and which can be the same width as or wider than the associated passage opening 33, its flow cross sections being expediently constant over its length. The grooves are provided in the outer circumference of the nozzle core 21 and are closed by the associated inner circumference of the nozzle cap 18 on the open longitudinal sides of the groove.
Die Ringschulter 36 liegt dicht an einer entsprechenden Ring¬ schulter der Düsenkappe 18 an, in die auch die Schaftab¬ schnitte 22, 23, 24 dicht und selbsthemmend eingreifen. Bei Pumpbetätigung strömt das Medium durch den Kanalabschnitt 29 und den Querkanal 31 in die wesentlich engeren Längskanäle 32 und dann in nochmals engere, in der Endfläche 39 vorgesehene Verbindungskanäle, durch welche das Medium in eine Rotations¬ strömung um die Düsenachse versetzt und dann durch den Düsen¬ kanal fein zerstäubt zum Gebrauch aufgetragen wird.The ring shoulder 36 lies tightly against a corresponding ring shoulder of the nozzle cap 18, into which the shaft sections 22, 23, 24 also engage in a tight and self-locking manner. When the pump is actuated, the medium flows through the channel section 29 and the transverse channel 31 into the much narrower longitudinal channels 32 and then into even narrower connecting channels provided in the end face 39, through which the medium is set into a rotational flow around the nozzle axis and then through the nozzles ¬ channel is atomized for use.
Zur Montage kann der Austragkopf 1 auch nach der Befestigung der Pumpe 3 am Behälter 6 auf den Betätigungsschaft 9 aufge¬ steckt werden, da eine hierbei erfolgende, durch Anschlag der Kolbeneinheit 4 begrenzte Pumpbetätigung infolge der vorgese¬ henen Volumenverhältnisse höchstens zu einer Medienfüllung des Kanalabschnittes 29, nicht jedoch zu einem Austrag von Medium führt. Das Verbindungsglied 26 kann in Ausgangsstellung der Pumpe in das Gehäuse 5 bzw. den Zylinderdeckel eingreifen und in Pumphub-Endstellung vollständig innerhalb des Gehäuses 5 liegen.For assembly, the discharge head 1 can also be plugged onto the actuating shaft 9 after the pump 3 has been fastened to the container 6, since a pump actuation taking place here, limited by the stop of the piston unit 4, due to the volume relationships provided, at most to fill the channel section 29 with media , but does not lead to the discharge of medium. The connecting member 26 can in the initial position Engage the pump in the housing 5 or the cylinder cover and lie completely inside the housing 5 in the pump stroke end position.
Gemäß den Fig. 2 bis 5 geht der Schaftabschnitt 25 mit annä¬ hernd kontinuierlicher Außenweite bis zur Ringschulter 36 bzw. dem Düsenkern 21 durch, wobei er am Ende einen angephasten Schaftabschnitt 22 zum leichteren Einführen in die am Innen¬ umfang über die gesamte Länge zylindrische Innenhülse 17 aufweisen kann.According to FIGS. 2 to 5, the shaft section 25 passes through with an approximately continuous outer width up to the annular shoulder 36 or the nozzle core 21, at the end of which it has a chamfered shaft section 22 for easier insertion into the cylindrical length of the inner circumference over the entire length May have inner sleeve 17.
Der zylindrische Abschnitt 29 des Auslaßkanales 28 geht in geringem Abstand vor dem Querkanal 31 in einen engeren Ab¬ schnitt 30 über, der gemäß Fig. 6 Flachquerschnitt derart hat, daß dadurch die Schenkel 38 gebildet sind, so daß der Außen¬ durchmesser des Düsenkernes 21 etwa in der Größenordnung des Abschnittes 29 liegen kann bzw. gegenüber dessen Innenweite nur etwa um die Tiefe der Längskanäle 32 größer ist.The cylindrical section 29 of the outlet channel 28 merges at a short distance in front of the transverse channel 31 into a narrower section 30 which, according to FIG. 6, has a flat cross section such that the legs 38 are formed thereby, so that the outer diameter of the nozzle core 21 may be approximately in the order of magnitude of section 29 or is only greater by approximately the depth of the longitudinal channels 32 compared to its inner width.
Gemäß Fig. 5 ist jeder Längskanal 32 im Querschnitt ringseg- mentförmig und über einen Verbindungskanal 40 etwa tangential an eine zentrale Kammer oder Vertiefung 41 angeschlossen. Der Verbindungskanal 40 und die Vertiefung 41 sind durch Ausneh¬ mungen in der Endfläche 39 gebildet. Jeder Verbindungskanal 40 nimmt vom Längskanal 32 in Richtung zur Vertiefung 41 im Quer¬ schnitt keilförmig ab, wobei er am weiteren Eintrittsende einen gegenüber dem Längskanal 32 nur etwa halb so großen Durchflu߬ querschnitt aufweist, nämlich nur über einen Teil der Breite dieses Längskanales 32 reicht. Eine Keilflanke 42 des nutför- migen Verbindungskanales 40 erstreckt sich etwa von einer Flanke des Längskanals 32 tangential an den Innenumfang der kreisrunden Vertiefung 41, deren Durchmesser in der Grös- senordnung der Breite des Längskanales 32 liegt. Dadurch wird bei einfacher Ausbildung eine hohe Zerstäubungswirkung er¬ zielt.5, each longitudinal channel 32 is in the form of a ring segment in cross section and is connected approximately tangentially to a central chamber or depression 41 via a connecting channel 40. The connecting channel 40 and the recess 41 are formed by recesses in the end surface 39. Each connecting channel 40 decreases in a wedge shape from the longitudinal channel 32 in the direction of the recess 41, and at the further entry end it has a flow cross-section which is only about half as large as that of the longitudinal channel 32, namely only extends over part of the width of this longitudinal channel 32 . A wedge flank 42 of the groove-shaped connecting channel 40 extends approximately from a flank of the longitudinal channel 32 tangentially to the inner circumference of the circular recess 41, the diameter of which is of the order of the width of the longitudinal channel 32. This will with a simple design, a high atomization effect is achieved.
Das Verbindungsglied 26 weist gemäß Fig. 4 eine mehrfach im Durchmesser abgesetzte Stecköffnung 27 und an deren offenem Ende eine Erweiterung für die Aufnahme eines entsprechend erweiterten Bundes des BetätigungsSchaftes 9 auf, in welchen gemäß Fig. 1 ein Schaftteil eines Kolbenkernes der Kolbenein¬ heit 4 so gesteckt werden kann, daß eine Kolbenmanschette mit vorbestimmter Axialspannung festgelegt ist.The connecting member 26 according to FIG. 4 has a plug opening 27 with a multiple diameter and at its open end an extension for receiving a correspondingly enlarged collar of the actuating shaft 9, in which, according to FIG. 1, a shaft part of a piston core of the piston unit 4 is so can be inserted that a piston sleeve is fixed with a predetermined axial tension.
Gemäß den Fig. 7 bis 10 geht der Außenumfang des Düsenkernes 21 unmittelbar in den Schaftabschnitt 22 über. Am freien Ende ist der Düsenkern 21 mit einer abgesetzten Ringschulter 43 ver¬ sehen, die mit der Düsenkappe 18 einen Ringkanal an der Außen¬ seite der Endwand 34 bildet. Der Auslaßkanal 28 bildet im Be¬ reich des Abschnittes 29 drei längsnutförmige, jedoch mitein¬ ander kommunizierende und sternförmig um die Mittelachse 10 angeordnete Kanäle, die bis zur Innenseite 35 der Stirnwand 34 reichen. Ein einziger bis alle Nutkanäle sind jeweils über einen Querkanal 31 und eine Durchtrittsöffnung 33 an einen Längskanal 32 angeschlossen, der in die Ringschulter 43 mündet. Dadurch können drei gleichmäßig über den Umfang verteilte Querkanäle 31 und entsprechend angeordnete Durchtrittsöffnungen 33 sowie Längskanäle 32 vorgesehen werden. Die jeweilige Durch¬ trittsöffnung 33 liegt etwa in der Ebene der Bodenwand des zu¬ gehörigen Nutkanales des Abschnittes 39. Die Querwand 34 ist über drei Schenkel mit dem geschlossenen Mantel des Düsenkernes 21 verbunden, wobei jeweils zwischen zwei benachbarten Schenkeln eine Durchtrittsöffnung 33 vorgesehen ist.7 to 10, the outer circumference of the nozzle core 21 merges directly into the shaft section 22. At the free end, the nozzle core 21 is provided with a stepped annular shoulder 43, which forms an annular channel with the nozzle cap 18 on the outer side of the end wall 34. The outlet channel 28 forms in the region of the section 29 three channels which are in the form of a longitudinal groove, but which communicate with one another and are arranged in a star shape around the central axis 10 and extend to the inside 35 of the end wall 34. A single to all groove channels are each connected via a transverse channel 31 and a passage opening 33 to a longitudinal channel 32 which opens into the annular shoulder 43. As a result, three transverse channels 31 uniformly distributed over the circumference and correspondingly arranged passage openings 33 and longitudinal channels 32 can be provided. The respective passage opening 33 lies approximately in the plane of the bottom wall of the associated groove channel of section 39. The transverse wall 34 is connected to the closed jacket of the nozzle core 21 via three legs, a passage opening 33 being provided between each two adjacent legs.
Die die jeweilige Durchtrittsöffnung 33 der Innenseite 39 gegenüberliegend begrenzende Schulter 36 liegt hier im Abstand vor dem Schaftabschnitt 22 im Mantel des Düsenkernes 21. Ist der Schaft durch die Innenhülse auf größerer Länge bzw. bis zu Verbindungsglied 26 ummantelt, so kann der Querkanal 31 auch wesentlich näher beim Verbindungsglied liegen und die Längs¬ kanäle 32 sind entsprechend verlängert.The shoulder 36 which delimits the respective passage opening 33 on the inside 39 lies at a distance here in front of the shaft section 22 in the jacket of the nozzle core 21. If the shaft is covered by the inner sleeve over a greater length or up to the connecting member 26, the transverse channel 31 can also be much closer to the connecting member and the longitudinal channels 32 are correspondingly lengthened.
Jedes beschriebene Merkmal kann bei allen Ausführungsformen vorgesehen werden. Each described feature can be provided in all embodiments.
