Abstract

The invention concerns an overhead door-closing unit in which the two opposed pistons (2, 3) usually used are replaced by a one-piece piston (1). This one-piece piston design increases the efficiency of the door-closing unit.

Description

Die Erfindung betrifft einen Obentürschließer gemäß dem Oberbegriff des Patentanspruches 1, bei dem der Dämpfungskolben und das Federstützglied aus einem gemeinsamen Teil hergestellt sind. Innerhalb einer Ausnehmung ist zwischen zwei Rollen eine Hubkurvenscheibe plaziert, die ihrerseits im Inneren des Türschließers gelagert und die austretende Schließerwelle mit einem Betätigungsarm verbunden ist, dessen anderes Ende mit einem Gleitstück einer Gleitschiene zusammenwirkt.The invention relates to an overhead door closer according to the preamble of Claim 1, in which the damping piston and the spring support member are made from a common part. Within a recess a cam disc is placed between two rollers in turn stored inside the door closer and the exiting Closer shaft is connected to an actuating arm, the other End cooperates with a slide of a slide rail.

Ein Obentürschließer mit einem Gleitschienengestänge ist der DE 40 38 720 C2 zu entnehmen. Dieser Gleitschienentürschließer ist für alle Montagearten geeignet, d.h. Rechts/Linksanschiag auf der Bandseite oder der Gegenbandseite sowohl in Normalmontage auf dem Türblatt als auch in der Kopfmontage auf dem Türrahmen. Dabei wird eine Hubkurvenscheibe verwendet, deren beide Kurvenbahnen symmetrisch aufgebaut sind. Durch die symmetrischen Kurvenbahnen wird in beiden Drehrichtungen ein gleicher Drehmomentenverlauf erzielt. Die Hubkurvenscheibe ist dabei auf einer Schließerwelle befestigt, die zum einen im unteren Teil des Gehäuses gelagert ist und in der anderen Richtung durch einen mit einem Lager versehenen Verschlußdeckel gehalten wird. Dabei kommt die Hubkurvenscheibe mit einer Rolle, die im Dämpfungskolben eingesetzt ist zum einen und auf der anderen Seite mit einer Rolle, die im Federstützglied eingesetzt ist, in Berührung. Dämpfungskolben und Federstützglied können unabhängige Bewegungen voneinander ausführen. Dafür werden sowohl der Dämpfungskolben durch eine Druckfeder als auch das Federstützglied durch die Druckfeder des Federspeichers so beaufschlagt, daß die beiden vorerwähnten Rollen innen an der Hubkurvenscheibe zum Anliegen kommen. Innerhalb des Dämpfungskolbens ist ein Rückschlag- und Überdruckventil vorhanden. An overhead door closer with a slide rail linkage is DE 40 38 720 C2. This slide rail door closer is for all types of installation suitable, i.e. Right / left angle on the hinge side or the Counter hinge side both in normal assembly on the door leaf and in the head mounting on the door frame. This is a cam disc used, the two cam tracks are symmetrical. Due to the symmetrical cam tracks, one turns in both directions same torque curve achieved. The cam disc is open a closer shaft attached, the one in the lower part of the housing is stored and in the other direction by one with a bearing provided closure lid is held. The cam disc comes here with a roller that is used in the damping piston on the one hand and on the other hand with a roller that is used in the spring support member is in touch. Damping pistons and spring support can be independent Execute movements of each other. For this both Damping piston by a compression spring and the spring support member acted upon by the compression spring of the spring accumulator so that the two the abovementioned rollers come to rest on the inside of the cam disc. There is a non-return and pressure relief valve inside the damping piston available.

Ein weiterer Türschließer wird in der DE 40 41 824 C1 beschrieben, bei dem ebenfalls ein separater Dämpfungskolben und ein separates Federstützglied vorhanden sind, die je mit einer Rolle ausgestattet und links und rechts in einem Gehäuse so plaziert sind, daß dazwischen die auf einer Welle befindliche Hubkurvenscheibe mit diesen Rollen in Eingriff steht. Sowohl der Dämpfungskolben als auch das Federstützglied sind jeweils durch eine Druckfeder kraftmäßig in Richtung auf die Hubkurvenscheibe beaufschlagt. Um ein Verdrehen des Federstützgliedes gegenüber dem Dämpfungskolben zu vermeiden, sind Sicherungsmittel vorhanden. Durch die Anbringung der Sicherungsmittel in Form von Stiften wird die Funktion des Türschließers in keinster Weise beeinträchtigt, da auch hier Dämpfungskolben und Federstützglied völlig getrennt voneinander arbeiten können. Die Sicherungsmittel sind dabei z.B. einerseits im Federstützglied fest verankert, und andererseits auf der gegenüberliegenden Seite innerhalb des Dämpfungskolbens in Sackbohrungen reibungslos eintauchbar. Dabei verlaufen die Sicherungsstäbe horizontal zur vertikal verlaufenden Achse der Türschließerwelle. Haben der Dämpfungskolben und das Federstützglied die Bestrebung, sich gegenüber dem anderen zu verdrehen, so wird durch die Sicherungsmittel dieses Verdrehen unterbunden, weil durch Anliegen an der Hubkurvenscheibe die Drehbewegung unterbunden wird.Another door closer is described in DE 40 41 824 C1, at which also has a separate damping piston and a separate spring support member are available, each equipped with a role and left and are placed on the right in a housing in such a way that on a Stroke cam disc is engaged with these rollers. Both the damping piston and the spring support member are each by means of a compression spring in the direction of the cam disc acted upon. To twist the spring support member relative to the Safety devices are available to avoid damping pistons. By the attachment of the securing means in the form of pins becomes the function of the door closer in no way affected, as here too damping pistons and spring support member can work completely separately. The securing means are e.g. on the one hand firmly in the spring support member anchored, and on the other hand on the opposite side inside of the damping piston can be immersed smoothly in blind holes. there the locking bars run horizontally to the vertical axis the door closer shaft. Have the damping piston and the spring support member the effort to twist towards the other is so this twisting is prevented by the securing means, because of concerns the rotary movement is prevented on the cam disc.

Die Aufgabe der vorliegenden Erfindung besteht darin, einen Obentürschließer in den Herstellkosten zu senken, wobei gleichzeitig der Wirkungsgrad des Türschließers erhöht werden soll.The object of the present invention is an overhead door closer to cut in manufacturing costs while maintaining efficiency the door closer should be increased.

Die Aufgabe der Erfindung wird durch einen Obentürschließer mit den Merkmalen des Patentanspruches 1 gelöst. Es wird ein einteiliger Kolben verwendet, der sowohl die Funktion des Dämpfungskolbens als auch des Federstützgliedes in sich vereint. Der Kolben ist dabei als langgestrecktes rundes Bauteil ausgeführt, das quasi in seinem mittleren Bereich eine Ausnehmung über die axiale Mitte hinaus aufweist, um die hierin zu plazierende Hubkurvenscheibe einsetzen zu können. Im Anschluß an die Ausnehmung befindet sich ein Durchbruch, der zum einen als Durchlaß für die Schließerwelle dient, aber auch gleichzeitig dem gesamten Kolben die Möglichkeit der axialen Verschiebung aufgrund der Drehbewegung der Schließerwelle ermöglicht. The object of the invention is achieved by an overhead door closer Features of claim 1 solved. It becomes a one-piece piston used that both the function of the damping piston and the Spring support member united in one. The piston is an elongated one round component that has a recess in its central area beyond the axial center to be placed therein To be able to use cam disc. Following the recess there is a breakthrough, on the one hand as a passage for the Closer shaft serves, but also the entire piston at the same time Possibility of axial displacement due to the rotary movement of the Closer shaft enables.

Durch die Wahl eines längeren Kolbens wird in der Zylinderbohrung eine bessere Führung und Abstützung erreicht. Dadurch werden die Querkräfte, welche immer auftreten, jedoch geringer gehalten, was gleichzeitig eine geringere Reibung bedeutet, und damit ist eine Erhöhung des Wirkungsgrades gegeben.By choosing a longer piston, one becomes in the cylinder bore better leadership and support achieved. In this way the lateral forces, which always occur, but kept lower, which is also a means less friction, and with it an increase in efficiency given.

Der Teil des Kolbens, der die Funktion eines Dämpfungskolbens übernimmt, ist dabei so gestaltet, daß die äußere Kolbenfläche in dem ihn umschließenden Gehäuse der Zylinderwandung ohne Dichtung geführt wird. Durch die Verwendung eines einstückigen Kolbens kann somit auch die, wie beim aufgezeigten Stand der Technik vorhandene zweite Druckfeder entfallen. In axialer Richtung weist der Bereich des Dämpfungskolbens eine Bohrung auf, die ein Rückschlag- und Überdruckventil aufnimmt. Im Anschluß an diese axiale Bohrung befindet sich eine axiale Ausnehmung zur Kolbenmitte für die Aufnahme einer Anlaufrolle. Diese Anlaufrolle wird durch einen Stift, der radial in den Dämpfungskolben in eine Sackbohrung oder Sturenbohrung eingesetzt wird, drehbar gehalten. Der Stift weist dabei an der zur Zylinderwandung weisenden Seite eine aus Kunststoff bestehende Schutzkappe auf, damit bei einem unbeabsichtigten Lösen dieses Stiftes keine Rattermarken im Bereich der Zylinderwandungen auftreten können.The part of the piston that functions as a damping piston is designed so that the outer piston surface in the surrounding it Housing of the cylinder wall is guided without a seal. By using a one-piece piston, the as in the prior art shown second compression spring omitted. The area of the damping piston points in the axial direction a bore that receives a check and pressure relief valve. in the Connected to this axial bore is an axial recess to the center of the piston for receiving a thrust roller. This thrust roller will through a pin that radially into the damping piston in a blind hole or stubborn hole is used, rotatably held. The pen points on the side facing the cylinder wall is made of plastic Protective cap on, in case of unintentional loosening this Pen no chatter marks occur in the area of the cylinder walls can.

Der Teil des Kolbens, der als Federstützglied ausgebildet ist, hat den gleichen Durchmesser wie der Teil des Dämpfungskolbens. Jedoch befindet sich im Inneren des Federstützgliedes eine Bohrung, in welche ein in axialer Richtung verschiebbares Innenteil eingesetzt werden kann. Dieses Innenteil weist an der äußeren Seite einen Ansatz auf, der zur Aufnahme und damit zur sicheren Plazierung der Druckfeder für den Energiespeicher dient. Das Innenteil weist eine in axialer Richtung verlaufende Bohrung auf, um das Dämpfungsmedium aus dem Federraum in den Druckraum abströmen zu lassen. Darüber hinaus befindet sich auch auf dieser Seite des Kolbens ebenfalls in axialer Richtung eine Ausnehmung, die ebenfalls dazu dient, eine Kraftübertragungsrolle aufzunehmen. Diese Kraftübertragungsrolle ist durch ein Nadellager auf einem Stift, der mit einem gewissen Spiel durch die äußeren Wandungen des Federstützgliedes hindurchgeht und gleichzeitig innerhalb des Innenteiles durch eine Preßpassung mit diesem kraft- und formschlüssig verbunden ist. Auch dieser Stift weist wieder in seinem zum Bereich der Zylinderwandung weisenden Ende eine aus Kunststoff bestehende Verschlußkappe auf.The part of the piston which is designed as a spring support member has the same Diameter as the part of the damping piston. However located a hole in the interior of the spring support member, in which a axially displaceable inner part can be used. This Inner part has an attachment on the outer side, which is for receiving and thus for the safe placement of the compression spring for the energy storage serves. The inner part has a bore running in the axial direction on to the damping medium from the spring chamber into the pressure chamber to let out. It is also located on this page the piston also has a recess in the axial direction, which also serves to receive a power transmission roller. This power transmission role is by a needle bearing on a pin that with a certain Game passes through the outer walls of the spring support member and at the same time within the inner part by an interference fit with this is positively and positively connected. This pen also points again in its end facing the area of the cylinder wall Plastic existing cap on.

Dadurch, daß das Innenteil maßlich mit der Innenbohrung des Federstützgliedes so abgestimmt ist, daß es in axialer Richtung verschiebbar ist, ist in einem gewissen Bereich, nämlich dem des Spieles zwischen dem radial eingesetzten Stift, für die Kraftübertragungsrolle eine Verschiebung des Innenteiles in axialer Richtung möglich. Dadurch wird immer sichergestellt, daß zum einen sowohl die Anlaufrolle als auch die Kraftübertragungsrolle sicher an der Hubkurvenscheibe in allen Bereichen bei einer Verdrehung der Hubkurvenscheibe anliegen, und zum anderen wird dadurch gleichzeitig erreicht, daß die Übertragung der Kräfte durch die Rollen, die sich in der axialen Mitte des Kolbens befinden, stattfindet und nicht durch die Kolbenaußenflächen. Hierdurch wird eine Erhöhung des Wirkungsgrades erreicht. Die Erhöhung des Wirkungsgrades stellt sich dadurch ein, daß der Kolben nicht das Bestreben hat, sich aufgrund der sonst außen angreifenden Kräfte, z.B. von der Druckfeder her, zu verkanten. Eine Verkantung wird ausgeschlossen, da durch die einstückige Art sowohl der Dämpfungskolben als auch das Federstützglied nicht in irgendeiner Art und Weise getrennt auswandern können. Diese bestehenden Kräfte innerhalb des Türschließers, die ein Auswandern der sonst üblicherweise einzeln vorhandenen Kolben bewirken, können hier nicht auftreten, da durch die Übertragung der Kräfte in der axialen Mittellinie, d.h. über die Kraftübertragungsrolle, Hubkurvenscheibe mit anschließender Anlaufrolle wird eine ideale Übertragung der Kräfte ausgeführt. Damit sind die Belastungen von den Außenflächen sowohl des Dämpfungskolbens als auch des Federstützgliedes weggenommen worden, was gleichzeitig bedeutet, daß durch das Nichtverkanten der einzelnen Kolben kein höherer Verschleiß und damit eine Herabsetzung des Wirkungsgrades eines solchen Obentürschließers gegeben ist, auch wie beim aufgezeigten Stand der Technik liegen beim einteiligen Kolben unter Belastung sowohl die Rolle des Dämpfungskolbens als auch die Rolle des Innenteiles des Federstützgliedes an den Kurvenbahnen der Hubkurvenscheibe an. Characterized in that the inner part dimensionally with the inner bore of the spring support member is adjusted so that it can be moved in the axial direction, is in a certain area, that of the game between the radially inserted pin, a shift for the power transmission roller of the inner part possible in the axial direction. This always ensures that on the one hand both the thrust roller and the power transmission roller securely on the cam disc in all areas at one Rotation of the cam disc is present, and the other is achieved at the same time that the transfer of forces through the roles, which are in the axial center of the piston takes place and not through the piston outer surfaces. This will increase efficiency reached. This increases the efficiency one that the piston does not strive to move due to the otherwise external forces, e.g. from the compression spring to tilt. Tilting is excluded because the one-piece type both the damping piston and the spring support member are not in any Can emigrate separately. This existing Forces inside the door closer that usually emigrate individually existing pistons cannot occur here because by transferring the forces in the axial center line, i.e. via the power transmission roller, cam disc with subsequent The thrust roller performs an ideal transfer of forces. With that the loads from the outer surfaces of both the damping piston and also the spring support member has been removed, which means at the same time that by not tilting the individual pistons no higher Wear and thus a reduction in the efficiency of such There is an overhead door closer, also as in the stand shown The technology of the one-piece piston is both under load Role of the damping piston as well as the role of the inner part of the Spring support member on the cam tracks of the cam disc.

Zur weiteren Erhöhung des Wirkungsgrades ist ein weiteres Mittel eingesetzt worden, nämlich eine Sicherungsplatte, die ein Verdrehen des gesamten Kolbens und damit auch Verkanten gegenüber der Hubkurvenscheibe unterbindet. Dieses wird dadurch erreicht, daß unter oder oberhalb der Anlaufrolle und der Kraftübertragungsrolle eine Sicherungsplatte eingelegt wird, die im mittleren Bereich einen Durchbruch aufweist, der das im Inneren des Gehäuses gelagerte Ende der Schließerwelle durchtreten läßt und auch in axialer Richtung soviel Bewegungsfreiheit gibt, daß der Kolben sich in axialer Richtung verschieben kann. Gleichzeitig wird ein Verdrehen des Kolbens gegenüber der Hubkurvenscheibe unterbunden, dadurch, daß die Sicherungsplatte entweder oberhalb oder unterhalb der Hubkurvenscheibe sich befindet. Würde sich der Kolben gegenüber der Hubkurvenscheibe verdrehen wollen, so wird diese Drehbewegung verhindert, weil die Sicherungsplatte an der Hubkurvenscheibe zur Anlage kommen würde.Another means is used to further increase the efficiency been, namely a locking plate that twists the entire Piston and thus tilting compared to the cam disc prevents. This is achieved in that below or above the thrust roller and the power transmission roller inserted a locking plate is, which has a breakthrough in the central area, which in End of the closer shaft mounted inside the housing can pass through and also so much freedom of movement in the axial direction that the piston can shift in the axial direction. At the same time there is a twisting of the piston opposite to the cam disc, characterized in that the locking plate either above or below the cam disc located. Would the piston face the stroke cam want to twist, this rotation is prevented because the locking plate would come into contact with the cam disc.

Die vorliegende Erfindung hat gegenüber dem aufgezeigten Stand der Technik, bei dem jeweils zwei Kolben gegenläufig laufen, durct, die Ausbildung eines einstückigen Kolbens den Vorteil, daß hier eine enorme Erhöhung des Wirkungsgrades vorliegt. Darüber hinaus kann eine Senkung der Herstellkosten dadurch erreicht werden, daß zum einen die zweite Druckfeder entfällt und zum anderen die Montagekosten drastisch gesenkt werden können. Hierzu kann z.B. der gesamte Kolben außerhalb des Gehäuses vormontiert werden. Diese wird als komplette Baugruppe in die Zylinderwandung des Gehäuses eingesetzt, wobei dann von oben die Hubkurvenscheibe zwischen die Anlaufrolle und die Kraftübertragungsrolle, die einen definierten Sitz aufweisen, hineingesetzt. Anschließend kann die Verschlußkappe für die austretende Schließerwelle eingesetzt werden und im Nachhinein die Druckfeder in das Gehäuse eingebracht und das Gehäuse an beiden Stirnseiten verschlossen werden.The present invention has compared to the prior art shown Technology in which two pistons run in opposite directions, the training a one-piece piston the advantage that there is an enormous increase the efficiency is present. It can also lower the Manufacturing costs can be achieved in that the second compression spring is eliminated and on the other hand the assembly costs are drastically reduced can. For this, e.g. the entire piston outside the housing be pre-assembled. This is inserted as a complete assembly in the cylinder wall of the housing, with the cam disc from above between the thrust roller and the power transmission roller, the have a defined seat. Then the Cap for the emerging closer shaft are used and afterwards the compression spring inserted into the housing and the housing be closed on both ends.

Aufgrund der vorliegenden kostengünstigen Konstruktion ist auch eine automatische Montage möglich, ohne daß hierbei die Qualität und auch der Wirkungsgrad eines solchen Obentürschließers vermindert würden.Due to the present inexpensive construction is also a automatic assembly possible, without sacrificing quality and the efficiency of such an overhead door closer would be reduced.

Within the closure 31 there is a Bearing 32 for pivoting a closer shaft 33. The other end of the The closer shaft 33 is inside the housing 23 in an inner bearing 18 pivoted. Is exactly between the two bearings 18, 32 in the axial center of the door closer a cam 19, the force and is positively connected to the closer shaft 33. The closer shaft 33 penetrates a piston 1 with the cam disc 19 Piston 1 is within an axial direction of the housing 23 Cylinder wall 30 slidable. On the one hand, the housing 23 is a closure cap is closed in the area of the piston and at the other end is after a compression spring 6 is inserted with a cap 24 and spring counter bearing 25 located thereon, the housing 23 closed overall.

Der Kolben 1 wird, wie es die Figur 2 deutlich macht, als gesamte Baugruppe innerhalb des Gehäuses 23 eingesetzt. Der Kolben 1 ist als einstückiges Teil ausgebildet und beinhaltet sowohl den Dämpfungskolben 2 als auch das Federstützglied 3. Hierzu weist der Kolben 1 in annähernd seinem mittleren Bereich eine radial hineingearbeitete Ausnehmung 4 auf, die sich über die axiale Mitte hinaus erstreckt. Im anschließenden verbleibenden Teil, nämlich der Verbindung zwischen dem Teil des Dämpfungskolbens 2 und dem des Federstützgliedes 3, ist ein Durchbruch 5 vorhanden, der es gestattet, die Schließerwelle 33 quasi durch den Kolben 1 durchzustecken. Die Ausnehmung 5 ist dabei nicht als kreisrunde Bohrung ausgeführt, sondern als Langloch, um dem Kolben 1 die Möglichkeit der axialen Bewegung geben zu können.The piston 1 is, as FIG. 2 clearly shows, as an entire assembly inserted within the housing 23. The piston 1 is in one piece Part formed and includes both the damping piston 2nd as well as the spring support member 3. For this purpose, the piston 1 has approximately a radially machined recess 4 in its central region, which extends beyond the axial center. In the following remaining Part, namely the connection between the part of the damping piston 2 and that of the spring support member 3, there is an opening 5, which allows the closer shaft 33 quasi through the piston 1st put through. The recess 5 is not a circular hole executed, but as an elongated hole to the piston 1 the possibility of to be able to give axial movement.

Betrachten wir zunächst den Teil des Kolbens 1, der als Dämpfungskolben 2 seine Aufgabe aufnimmt. In axialer Richtung befindet sich innerhalb des Dämpfungskolbens 2 eine Bohrung, in welche ein Rückschlag- und Überdruckventil eingebaut ist. Dieses Rückschlag- und Überdruckventil 21 ist für die ordnungsgemäße Funktion des Obentürschließers notwendig. Zum Bereich der Ausnehmung 4 hin weist der Dämpfungskolben 2 eine radiale Bohrung auf, die vorzugsweise als Sackbohrung 16 oder Stufenbohrung ausgeführt wird. Innerhalb der Bohrung 16 wird ein Stift 15 kraft- und formschlüssig eingebracht, der gleichzeitig die in einer Ausnehmung befindliche drehgelagerte Anlaufrolle 14 hält. Gegen unbeabsichtigtes Herausrutschen ist der Stift 15 in seinem zur Zylinderwandung 30 weisenden Ende mit einer Verschlußkappe 10, die vorzugsweise aus Kunststoff besteht, ausgestattet. Dadurch wird gleichzeitig vermieden, daß hier Rattermarken innerhalb der Zylinderwandung 30 auftreten können.Let us first consider the part of the piston 1 that acts as a damping piston 2 takes up its task. In the axial direction is inside the Damping piston 2 a bore in which a check and pressure relief valve is installed. This check and pressure relief valve 21 is necessary for the proper function of the overhead door closer. To the In the area of the recess 4, the damping piston 2 has a radial one Hole on, preferably as a blind bore 16 or stepped bore is performed. Within the bore 16, a pin 15 is positively and positively introduced, which is at the same time in a recess rotatably mounted thrust roller 14 holds. Against accidental slipping out is the pin 15 in its end facing the cylinder wall 30 with a cap 10, which is preferably made of plastic. This also avoids chatter marks within the cylinder wall 30 can occur.

Betrachten wir nun den Teil des Kolbens 1, der als Federstützglied 3 seine Aufgabe übernimmt. Das Federstützglied 3 ist in seinem inneren Bereich mit einer Bohrung versehen, in welche ein Innenteil 8 längs in axialer Richtung verschiebbar eingesetzt wird. Dieses Innenteil 8 dient zur Anlage einer Druckfeder 6. Hierfür befindet sich an dem Innenteil 8 ein Ansatz 7, der verhindert, daß die Druckfeder 6 sich aus der axialen Lage verschieben kann. Innerhalb des Innenteiles 8 befindet sich vorzugsweise in der Mitte eine Bohrung 26, die es gestattet, das Dämpfungsmedium von dem drucklosen Raum zum Druckraum und zurückströmen zu lassen.Let us now consider the part of the piston 1, which as its spring support member 3 Task takes over. The spring support member 3 is in its inner region provided with a hole in which an inner part 8 longitudinally in the axial Slidable direction is used. This inner part 8 is used for plant a compression spring 6. For this there is an extension 7 on the inner part 8, which prevents the compression spring 6 from moving out of the axial position can. Within the inner part 8 is preferably in the Center a bore 26 that allows the damping medium from the to let pressure-free space flow to the pressure space and back.

Auch in dem Federstützglied 3 ist eine Rolle als Kraftübertragungsrolle 11 vorhanden, die jedoch nach einer anderen Art als die in dem Dämpfungskolben 2 eingesetzt ist. Die Kraftübertragungsrolle 11 hat ein Nadellager 29, durch dessen Bohrung ein Stift 9 hindurchgeht. Gleichzeitig wird dieser Stift 9 radial in einer Bohrung innerhalb des Innenteiles 8 durch eine Preßpassung gehalten. Jedoch hat der Stift 9 eine größere Länge als der Durchmesser des Innenteiles 8 und ragt somit mit seinen Enden in Bereiche 12, 13 der Außenwandung des Federstützgliedes 3. Hierzu sind in dem Federstützglied 3 Bohrungen vorhanden, die jedoch ein Spiel 28 haben, so daß das Innenteil 8 in axialer Richtung bei eingesetztem Stift 9 sich um ein vorbestimmtes Maß verschieben kann. Dabei weist der Bereich des Federstützgliedes 3 eine Sackbohrung bzw. Stufenbohrung 17 auf, und der Stift 9 hat an seinem anderen Ende ebenfalls eine Verschlußkappe 10, die auch hier das Inkonktaktkommen des Stiftes 9 mit der Zylinderwandung 30 verhindert.Also in the spring support member 3 is a role as a power transmission roller 11 present, but in a different way than that in the damping piston 2 is inserted. The power transmission roller 11 has a needle bearing 29, through the bore of which a pin 9 passes. At the same time, this Pin 9 radially in a bore within the inner part 8 by an interference fit held. However, the pin 9 has a greater length than that Diameter of the inner part 8 and thus protrudes with its ends in areas 12, 13 of the outer wall of the spring support member 3 the spring support member has 3 holes, but they have a game 28, so that the inner part 8 in the axial direction when the pin 9 is inserted can shift by a predetermined amount. The area shows of the spring support member 3 has a blind bore or stepped bore 17 on, and the pin 9 also has a cap at its other end 10, which here also the contact of the pin 9 with the cylinder wall 30 prevented.

Gegen unbeabsichtigtes Drehen des Kolbens 1 gegenüber der Hubkurvenscheibe 19 ist eine Sicherungsplatte 20, die durch die Stifte 9, 15 gleichzeitig in ihrer Lage gehalten wird, vorhanden. Dabei kann die Sicherungsplatte 20 sowohl unterhalb als auch oberhalb der Anlaufrolle 14 und der Kraftübertragungsrolle 11 eingesetzt werden. Die Sicherungsplatte 20 hat dabei in ihrem mittleren Bereich einen annähernd gleichartig gestalteten Durchbruch, wie der Durchbruch 5, der sich in dem Kolben 1 befindet. Durch die Sicherungsplatte 20 ist es sichergestellt, daß eine Verdrehung des Kolbens 1 gegenüber der axialen bzw. radialen Ebene der Schließerwelle 33 ausgeschlossen wird. Against unintentional rotation of the piston 1 in relation to the cam disc 19 is a locking plate 20 which is held by the pins 9, 15 is held in place at the same time. The locking plate 20 both below and above the thrust roller 14 and the power transmission roller 11 are used. The locking plate 20 has an approximately similar design in its central area Breakthrough, such as the breakthrough 5, which is located in the piston 1. The locking plate 20 ensures that rotation of the piston 1 with respect to the axial or radial plane of the closer shaft 33 is excluded.
