Description

Die Erfindung betrifft eine Einrichtung zur Übertragung einer Antriebskraft von einem ersten Bauteil auf an lamellenartiges Ventilglied gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for transmitting a driving force from a first component to a lamellar valve member according to the preamble of claim 1.

Eine derartige Einrichtung ist aus der DE-A-33 29 790 bekannt. Dort wird in einem Ventilträger eine Antriebskraft zwischen einem ersten Bauteil (Mitnehmer 15) und einem zweiten Bauteil (Lamelle 13) über einen einerseits mit dem ersten Bauteil und andererseits mit dem zweiten Bauteil in Eingriff stehenden Deckel (Flachschieber 34) übertragen, wobei das erste Bauteil in einem Gehäuse verschiebbar geführt ist und der Deckel das Gehäuse abdichtet. Der Deckel wird durch Eingriff mit einem aus dem Gehäuse herausregenden Teil des ersten Bauteils mit dem ersten Bauteil verschoben. Damit der Deckel bei dieser Verschiebung jederzeit seine Abdichtfunktion erfüllen kann, muß er in Richtung der Verschiebeachse ausreichend bemessen sein, das Gehäuse, insbesondere dessen für das Herausragen des vorstehend erwähnten Teiles erforderlichen Durchbruch, in jeder Stellung des ersten Bauteils zu überdecken. Das bedeutet, daß der Deckel in Richtung der Verschiebeachse doppelt so lang wie der Gehäusedurchbruch sein muß. Daraus folgt, daß der Deckel in Richtung der Verschiebeachse erheblichen Platz beansprucht, da die Baulänge des Deckels in dieser Richtung in jeder Stellung des ersten Bauteils, beispielsweise auch in dessen Ausgangslage, untergebracht werden muß. Dieser Platz kann häufig nicht oder nicht problemlos zur Verfügung gestellt werden.Such a device is known from DE-A-33 29 790. There, a driving force is transmitted in a valve carrier between a first component (driver 15) and a second component (lamella 13) via a cover (flat slide valve 34) which is in engagement with the first component on the one hand and with the second component on the other hand, the first component is slidably guided in a housing and the cover seals the housing. The cover is displaced with the first component by engagement with a part of the first component which projects out of the housing. So that the cover can fulfill its sealing function at any time during this displacement, it must be dimensioned sufficiently in the direction of the displacement axis to cover the housing, in particular its opening required for the protruding part mentioned above, in every position of the first component. This means that the cover in the direction of the displacement axis must be twice as long as the housing opening. It follows that the cover takes up considerable space in the direction of the displacement axis, since the overall length of the cover in this direction in any position of the first component, for example, also in its starting position, must be accommodated. This space can often not be made available or cannot be made available without problems.

Aus der DE-C-2 241 687 ist eine Einrichtung zur Übertragung einer Antriebskraft zwischen einem ersten, in dem Gehäuse verschiebbar geführten, Bauteil und einem zweiten, in dem Gehäuse drehbar gelagerten, Bauteil bekannt. Die Übertragung erfolgt über einen in dem Gehäuse drehbar gelagerten Hebel, der mit innerhalb des Gehäuses angeordneten Teilen des ersten und des zweiten Bauteils im Eingriff steht.DE-C-2 241 687 discloses a device for transmitting a driving force between a first component which is displaceably guided in the housing and a second component which is rotatably mounted in the housing. The transmission takes place via a lever which is rotatably mounted in the housing and which engages with parts of the first and second components arranged inside the housing.

Der Erfindung liegt deshalb die Aufgabe zugrunde eine Einrichtung der eingangs genannten Art mit einfachen Mitteln derart zu verbessern, daß ihr Platzbedarf in Richtung der Verschiebeachse des ersten Bauteils erheblich verringert werden kann.The invention is therefore based on the object of improving a device of the type mentioned at the beginning with simple means such that its space requirement in the direction of the displacement axis of the first component can be considerably reduced.

Diese Aufgabe wird durch die im Patentanspruch 1 angegebene Erfindung gelöst. Weiterbildungen, vorteilhafte Ausgestaltungen und ein vorteilhaftes Anwendungsgebiet der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by the invention specified in claim 1. Further developments, advantageous refinements and an advantageous field of application of the invention are specified in the subclaims.

Die Erfindung eignet sich für alle Arten der Verschiebbarkeit des ersten Bauteils; die Verschiebbarkeit kann beispielsweise geradlinig sein und/oder entlang einer gekrümmten Bahn erfolgen.The invention is suitable for all types of displaceability of the first component; the displaceability can, for example, be straight and / or take place along a curved path.

Dadurch, daß der Deckel bei der Verschiebung bzw. der Bewegung der beteiligten Bauteile erfindungsgemäß gedreht statt verschoben wird, ermöglicht die Erfindung eine Verringerung der Relativbewegungen zwischen Deckel und Gehäuse und damit eine Verringerung der entsprechenden Reibarbeit mit einer Erhöhung des Wirkungsgrads der Einrichtung als Folge.Characterized in that the cover is rotated instead of moved according to the invention during the displacement or the movement of the components involved, the invention enables a reduction in the relative movements between the cover and the housing and thus a reduction in the corresponding friction work with an increase in the efficiency of the device as a result.

Die Antriebskraft kann von jedem der beteiligten Bauteile ausgehen.The driving force can come from any of the components involved.

Die Erfindung ist für alle Arten Bewegung des zweiten Bauteils geeignet. Beispielhaft ist an eine translatorische Bewegung (Verschiebung) oder eine Schwenkbewegung um eine Drehachse zu denken, die im wesentlichen parallel zur Drehachse des Deckels verlaufen kann. Die Drehachse des Deckels kann ihrerseits im wesentlichen quer zur Verschiebeachse des ersten Bauteils verlaufend angeordnet sein.The invention is suitable for all types of movement of the second component. An example is one translatory movement (displacement) or a pivoting movement to think about an axis of rotation, which can run essentially parallel to the axis of rotation of the lid. The axis of rotation of the cover can in turn be arranged to run essentially transversely to the axis of displacement of the first component.

Vorteilhaft läßt sich die Erfindung in einem Fall anwenden, in dem ein Bauteil zwischen zwei Endstellungen verschiebbar bzw. bewegbar ist und dabei das andere Bauteil zur Mitbewegung bzw. Mitverschiebung zwischen zwei den erwähnten Endstellungen zugeordneten Endstellungen antreibt.The invention can advantageously be used in a case in which one component can be moved or moved between two end positions and thereby drives the other component to move or move between two end positions assigned to the mentioned end positions.

In einer Ausgestaltung ist das erste Bauteil als Mitnehmer eines im Gehäuse angeordneten Stellantriebs zur Bewegung des zweiten Bauteils ausgebildet. In diesem Fall kommt es also auf den Antrieb des zweiten Bauteils an. Ein derartiger Fall liegt beispielsweise vor, wenn das zweite Bauteil als lamellenartiges Ventilglied eines von diesem Ventilglied und wenigstens einer Gehäuseöffnung gebildeten Ventils ausgebildet ist. Das Ventilglied ist in diesem Fall zwischen zwei Endstellungen schwenkbar, in deren einer es die Gehäuseöffnung freigibt (öffnet) und in deren anderer es die Gehäuseöffnung überdeckt (d. h. schließt, sofern das Ventilglied nicht, etwa durch Unterdruck quer zur Schwenkrichtung, von der Gehäuseöffnung abgehoben wird).In one embodiment, the first component is designed as a driver of an actuator arranged in the housing for moving the second component. In this case, the drive of the second component is important. Such a case exists, for example, when the second component is designed as a lamellar valve member of a valve formed by this valve member and at least one housing opening. In this case, the valve member can be pivoted between two end positions, in one of which it opens (opens) the housing opening and in the other it covers the housing opening (ie closes unless the valve member is lifted from the housing opening, for example by negative pressure transversely to the pivoting direction) ).

Die Eingriffe zwischen Deckel und erstem Bauteil einerseits sowie Deckel und zweitem Bauteil andererseits können auf jede geeignete Weise erfolgen.The interventions between the cover and the first component on the one hand and the cover and the second component on the other can be carried out in any suitable manner.

Kostengünstige Lösungen hierfür sind in den Patentansprüchen 10, 11 und 12 angegeben. Die in diesen Ansprüchen angegebene Anordnung der Führungsschlitze gewährleistet die nach den Patentansprüchen 3 und/oder 4 vorteilhafte zu seiner Drehachse im wesentlichen kräftefreie Anordnung des Deckels.Cost-effective solutions for this are given in claims 10, 11 and 12. The arrangement of the guide slots specified in these claims ensures the arrangement of the cover which is advantageous in terms of its axis of rotation and which is advantageous according to claims 3 and / or 4.

Eine Ausgestaltung, in der der Deckel die Gehäusekonturen nicht beeinflußt bzw. beeinträchtigt, ergibt sich, wenn der Deckel im Gehäuse bis zur Bündigkeit seiner dem Gehäuse abgewandten Fläche mit einer den Deckel umgebenden Gehäuseoberfläche versenkt ist. Diese Gehäuseoberfläche kann eine besonders angeordnete Gehäuseoberfläche sein, beispielsweise eine angesenkte, aber auch die äußere Gehäuseoberfläche schlechthin oder eine innere Gehäuseoberfläche.An embodiment in which the cover does not influence or impair the housing contours results if the cover is sunk in the housing to a flush surface of the housing facing away from the housing with a surface surrounding the cover. This housing surface can be a specially arranged housing surface, for example a countersunk, but also the outer housing surface per se or an inner housing surface.

Die eben erwähnte versenkte Anordnung des Deckels ermöglicht in vorteilhafter Weise, daß das zweite Bauteil auf der erwähnten Gehäuseoberfläche und der dem Gehäuse abgewandten Seite des Deckels geführt werden kann.The above-mentioned recessed arrangement of the cover advantageously enables the second component to be guided on the housing surface mentioned and on the side of the cover facing away from the housing.

Durch die Möglichkeit, die Lage der Eingriffstellen auf dem Deckel und die Abstände der Eingriffsstellen von dessen Drehachse zu variieren, sind ohne nennenswerten zusätzlichen Aufwand, wenn nicht ohne zusätzlichen Aufwand überhaupt, unterschiedliche Kraft- bzw. Wegübersetzungen zwischen den beteiligten Bauteilen ausführbar.Due to the possibility of varying the position of the engagement points on the cover and the distances of the engagement points from its axis of rotation, different force or path ratios between the components involved can be carried out without any significant additional effort, if not without any additional effort at all.

Die Drehbare Lagerung des Deckels kann auf jede geeignete Art ausgeführt werden. In einer Ausgestaltung weist der Deckel zu diesem Zweck wenigstens eine zu seiner Drehachse drehsymmetrische Mantelfläche auf, mit der er in einer dazu kompatiblen Mantelfläche des Gehäuses radial gelagert ist. Diese Mantelfläche kann die äußere, die Querabmessung des Deckels bestimmende, Mantelfläche oder eine innere Mantelfläche sein. Im erstgenannten Fall müßte zwischen der Mantelfläche des Deckels und der dazu kompatiblen Mantelfläche des Gehäuses auch die Abdichtung des Gehäuses erfolgen.The lid can be rotated in any suitable manner. In a For this purpose, the cover has at least one lateral surface that is rotationally symmetrical with respect to its axis of rotation and with which it is mounted radially in a lateral surface of the housing that is compatible with it. This outer surface can be the outer outer surface, which determines the transverse dimension of the cover, or an inner outer surface. In the former case, the housing should also be sealed between the outer surface of the cover and the outer surface of the housing that is compatible with it.

Die vorgenannten Mantelflächen beschreiben im Grundriß je nach ihrer Ausbildung wenigstens einen Kreis. Zur Realisierung der geringstmöglichen Abmessungen quer zur Drehachse des Deckels kann der Durchmesser der Mantelflächen so bemessen sein, daß ein innerhalb des Grundrisses der Mantelfläche des Gehäuses angeordneter Durchbruch in Form eines Gehäuseschlitzes, in dem das erste Bauteil in Richtung seiner Verschiebeachse geführt ist, wenigstens angenähert nach Art einer Sehne in diesem Grundriß liegt.Depending on their design, the aforementioned lateral surfaces describe at least one circle in the plan. In order to achieve the smallest possible dimensions transversely to the axis of rotation of the cover, the diameter of the lateral surfaces can be dimensioned such that an opening in the form of a housing slot, in which the first component is guided in the direction of its displacement axis, is arranged within the outline of the lateral surface of the housing, at least approximately Kind of a tendon lies in this floor plan.

Die Entlastung der drehbaren Lagerung des Deckels von der Dichtungsfunktion wird ermöglicht durch eine Ausgestaltung, in der das Gehäuse in einer quer zur Drehachse des Deckels liegenden Ebene einen die Mantelfläche einschließenden Dichtsitz aufweist, auf dem der Deckel mit einem dazu kompatiblen und quer zu seiner Drehachse angeordneten Dichtsitz aufliegt. Die so geschaffene Abdichtung ist also der drehbaren Lagerung vorgeschaltet, entlastet diese damit nicht nur von der Dichtungsfunktion, sondern schützt sie auch vor Einflüssen, die auf der dem Gehäuse abgewandten Seite des Deckels bzw. der dieser Seite des Deckels zugeordneten inneren oder äußeren Oberfläche des Gehäuses ihren Ursprung haben.Relieving the rotatable mounting of the cover from the sealing function is made possible by an embodiment in which the housing has a sealing seat enclosing the lateral surface in a plane lying transverse to the axis of rotation of the cover, on which the cover is arranged with a compatible one and arranged transversely to its axis of rotation Sealing seat rests. The seal created in this way precedes the rotatable bearing, not only relieving it of the sealing function, but also protecting it also against influences that originate on the side of the cover facing away from the housing or on the inner or outer surface of the housing assigned to this side of the cover.

Im Grundriß kann die äußere Mantelfläche des Deckels jeden beliebigen Verlauf zeigen. Mit gleichbleibendem Platzbedarf in allen Drehstellungen quer zu seiner Drehachse läßt sich der Deckel ausführen, wenn seine äußere Mantelfläche drehsymmetrisch zu seiner Drehachse ist, also je nach Ausbildung, wenigstens einen Kreis als Grundriß hat. Die weiter oben erwähnte Ausgestaltung mit der drehbaren Lagerung vorgeschalteter Abdichtung läßt sich platzsparend ausgestalten, indem die Dichtsitze von Deckel und Gehäuse jeweils auf einer Übergangsfläche zwischen den äußeren Mantelflächen und den zur drehbaren Lagerung des Deckels dienenden Mantelflächen angeordnet sind.In the floor plan, the outer surface of the cover can show any course. With a constant space requirement in all rotational positions transverse to its axis of rotation, the cover can be designed if its outer lateral surface is rotationally symmetrical to its axis of rotation, that is, depending on the design, has at least one circle as a plan. The embodiment mentioned above with the rotatable bearing upstream seal can be designed to save space by arranging the sealing seats of the cover and housing on a transition surface between the outer lateral surfaces and the lateral surfaces serving to rotatably support the cover.

Die erwähnten Mantelflächen des Deckels einerseits und des Gehäuses andererseits können auf alle geeigneten und unter Wahrung der Funktion miteinander kompatiblen Arten ausgebildet sein. Beispielsweise können beide Mantelflächen zylindrisch, konisch oder ballig sein. Es können aber auch beispielsweise die deckelseitige Mantelfläche zylindrisch und die gehäuseseitige Mantelfläche konisch oder ballig sein.The mentioned lateral surfaces of the cover on the one hand and of the housing on the other hand can be designed in all suitable and compatible ways while maintaining their function. For example, both lateral surfaces can be cylindrical, conical or crowned. However, the cover-side lateral surface can also be cylindrical, for example, and the housing-side lateral surface can be conical or spherical.

Auch die oben erwähnten Dichtsitze des Gehäuses und des Deckels können auf alle geeigneten miteinander kompatiblen Arten ausgebildet sein. In Betracht kommen sämtliche Paarungen mit Flächen- oder Linienberührung. Auch kann eine eigene Dichtung zwischen den genannten Dichtsitzen angeordnet sein.The above-mentioned sealing seats of the housing and of the cover can also be designed in all suitable mutually compatible ways. In consideration all pairings come with surface or line contact. A separate seal can also be arranged between the sealing seats mentioned.

In den nachstehenden Ausführungen wird auf die jeweils in Betracht kommende Figur nur insoweit Bezug genommen, als dies zur Klarstellung unvermeidbar ist.In the explanations below, reference is made to the figure in question only to the extent that this is unavoidable for clarification.

Der dargestellte Ventilträger weist ein als Platte ausgebildetes Gehäuse (1) auf, in und auf dem eine Einrichtung zur Übertragung einer Antriebskraft zwischen zwei Bauteilen (22, 2) angeordnet ist. Als erstes Bauteil (22) ist der Mitnehmer eines im Gehäuse (1) angeordneten, generell mit (8) bezeichneten Stellantriebs vorgesehen. Das erste Bauteil (22) ist im Gehäuse (1) verschiebbar geführt. Die Führung erfolgt in einem (geraden) Gehäuseschlitz (7). Dem Gehäuseschlitz (7) gegenüberliegend weist das Gehäuse (1) eine Öffnung (27) auf, durch die das erste Bauteil (22) herausgeschlagen werden kann. Der Gehäuseschlitz (7) ist von einem Deckel (5) derart abgedeckt, daß dieser das Gehäuse (1) gegen Einflüsse, die auf der dem Gehäuse (1) abgewandten Seite des Deckels (5) bzw. der dieser Seite des Deckels (5) zugeordneten Seite des Gehäuses (1) ihren Ursprung haben, abdichtet.The valve carrier shown has a housing (1) in the form of a plate, in and on which a device for transmitting a driving force between two components (22, 2) is arranged. The first component (22) is the driver of an actuator arranged in the housing (1) and generally designated (8). The first component (22) is slidably guided in the housing (1). The guidance takes place in a (straight) housing slot (7). Opposite the housing slot (7), the housing (1) has an opening (27) through which the first component (22) can be knocked out. The The housing slot (7) is covered by a cover (5) in such a way that it protects the housing (1) against influences on the side of the cover (5) facing away from the housing (1) or that side of the cover (5) Side of the housing (1) have their origin seals.

Das erste Bauteil (22) weist einen aus dem Gehäuse (1), speziell aus dem Gehäuseschlitz (7), herausragenden Teil (21) auf, der mit dem Deckel (5) im Eingriff steht. Der Deckel (5) ist im Gehäuse (1) drehbar gelagert, und zwar um eine im wesentlichen quer zur Verschiebeachse (Doppelpfeil V) des ersten Bauteils (22) verlaufende Drehachse (6), derart, daß infolge des Eingriffs zwischen Deckel (5) und erstem Bauteil (22) einer Drehung des Deckels (5) eine Verschiebung (V) des ersten Bauteils (22) entspricht.The first component (22) has a part (21) protruding from the housing (1), especially from the housing slot (7), which engages with the cover (5). The cover (5) is rotatably mounted in the housing (1), namely about an axis of rotation (6) extending essentially transversely to the displacement axis (double arrow V) of the first component (22), such that, as a result of the engagement between the cover (5) and the first component (22) of a rotation of the cover (5) corresponds to a displacement (V) of the first component (22).

Die Drehachse (6) des Deckels (5) ist in Fig. 2 als Mittellinie des Deckels (5) dargestellt, während Fig. 1 nur ihre punktförmige Projektion zeigt.The axis of rotation (6) of the cover (5) is shown in FIG. 2 as the center line of the cover (5), while FIG. 1 only shows its point projection.

Als zweites Bauteil (2) ist ein lamellenartiges Ventilglied vorgesehen, das um eine zu der Drehachse (6) parallele Schwenkachse (12) im Gehäuse (1) schwenkbar gelagert ist. Dargestellt ist die Schwenkachse (12) in Fig. 1 als Mittelpunkt eines nicht näher bezeichneten, das zweite Bauteil (2) radial lagernden Schwenkbolzens. Die Schwenkbewegung des zweiten Bauteils (2) ist durch einen Doppelpfeil (S) angedeutet. Mit dem zweiten Bauteil (2) steht der Deckel (5) auf seiner dem Gehäuse (1) abgewandten Seite im Eingriff.A lamellar valve member is provided as the second component (2) and is pivotally mounted in the housing (1) about a pivot axis (12) parallel to the axis of rotation (6). The pivot axis (12) is shown in FIG. 1 as the center of an unspecified pivot pin which radially supports the second component (2). The pivoting movement of the second component (2) is indicated by a double arrow (S). The cover (5) engages with the second component (2) on its side facing away from the housing (1).

Das erste Bauteil (22) ist zwischen zwei Endstellungen verschiebbar, die in Fig. 2 mit (I) bzw. (II) bezeichnet sind. Bei seiner Verschiebung zwischen diesen Endstellungen treibt das erste Bauteil (22) in weiter unten beschriebener Weise das zweite Bauteil (2) zwischen zwei diesen Endstellungen zugeordneten (Schwenk-) Endstellungen an. Die der Stellung (I) des ersten Bauteils (22) zugeordnete Endstellung des zweiten Bauteils (2) ist in den Figuren dargestellt. Das zweite Bauteil (2) bildet mit einer Gehäuseöffnung (9), welche die Mündung eines Gehäusekanals ist, ein Einlaßventil (2, 9). In seiner der Stellung (I) zugeordneten Endstellung überdeckt das zweite Bauteil die Gehäuseöffnung (9) und schließt dadurch das Einlaßventil (2, 9), sofern es nicht durch eine Kraft quer zur Schwenkbewegung, etwa infolge eines Unterdrucks, von der Gehäuseöffnung (9) abgehoben wird. In seiner der Stellung (II) entsprechenden Endstellung gibt das zweite Bauteil (2) die Gehäuseöffnung (9) frei und öffnet dadurch das Einlaßventil (2, 9). Die Darstellung zeigt noch eine zweite Gehäuseöffnung (10), mit der das zweite Bauteil (2) ein weiteres Einlaßventil (2, 10) bildet, für welches die soeben getroffenen Feststellungen entsprechend gelten.The first component (22) can be displaced between two end positions, which are denoted by (I) or (II) in FIG. 2. When it moves between these end positions, the first component (22) drives the second component (2) between two (swivel) end positions assigned to these end positions in the manner described below. The end position of the second component (2) assigned to the position (I) of the first component (22) is shown in the figures. The second component (2) forms an inlet valve (2, 9) with a housing opening (9), which is the mouth of a housing channel. In its end position assigned to position (I), the second component covers the housing opening (9) and thereby closes the inlet valve (2, 9) unless it is exerted by a force transversely to the pivoting movement, for example as a result of a negative pressure, from the housing opening (9) is lifted off. In its end position corresponding to position (II), the second component (2) releases the housing opening (9) and thereby opens the inlet valve (2, 9). The illustration also shows a second housing opening (10) with which the second component (2) forms a further inlet valve (2, 10), for which the determinations just made apply accordingly.

Die Eingriffstellen zwischen Deckel (5) und erstem Bauteil (22) einerseits sowie zwischen Deckel (5) und zweitem Bauteil (2) andererseits sind so ausgebildet, daß die Bauteile (22 bzw. 2) bei der Übertragung einer Antriebskraft zwischen den Bauteilen auf den Deckel (5) quer zu dessen Drehachse (6) im wesentlichen keine Kräfte, mit anderen Worten: im wesentlichen keine Radialkräfte auf den Deckel (5) ausüben können. Dadurch ist die verklemmungsfreie Übertragung der Antriebskraft zwischen den Bauteilen sichergestellt.The points of engagement between the cover (5) and the first component (22) on the one hand and between the cover (5) and the second component (2) on the other hand are designed so that the components (22 and 2) when transmitting a driving force between the components on the Cover (5) transverse to its axis of rotation (6) essentially no forces, in other words: in can exert essentially no radial forces on the cover (5). This ensures that the drive force is transmitted without jamming between the components.

Zur Herstellung derartiger Eingriffe sind die Eingriffstellen beim Ausführungsbeispiel wie folgt ausgeführt.To produce such interventions, the engagement points in the exemplary embodiment are designed as follows.

Auf seiner dem Gehäuse (1) zugewandten Seite weist der Deckel (5) einen im wesentlichen auf seine Drehachse (6) zu gerichteten Führungsschlitz (20) auf, in welchem der aus dem Gehäuse (1) herausragende Teil (21) des ersten Bauteils (22) geführt ist. Andererseits weist der Deckel (5) auf seiner dem Gehäuse (1) abgewandten Seite einen Mitnehmer (4) auf, der in einem in dem zweiten Bauteil (2) ausgebildeten länglichen Führungsschlitz (3) in dessen Längsrichtung verschiebbar geführt ist, welche Längsrichtung im wesentlichen quer zur Schwenkrichtung (S) verläuft.On its side facing the housing (1), the cover (5) has a guide slot (20) which is essentially directed towards its axis of rotation (6) and in which the part (21) of the first component (21) protruding from the housing (1) 22) is performed. On the other hand, the cover (5) has on its side facing away from the housing (1) a driver (4) which is guided in an elongated guide slot (3) formed in the second component (2) in the longitudinal direction thereof, which longitudinal direction essentially runs transversely to the swivel direction (S).

Auf nicht dargestellte Weise könnte zur Herstellung des Eingriffs zwischen Deckel und zweitem Bauteil die Zuordnung von Mitnehmer und Führungsschlitz zu Deckel und zweitem Bauteil auch vertauscht werden.In a manner not shown, the assignment of driver and guide slot to cover and second component could also be interchanged to produce the engagement between cover and second component.

Der Deckel (5) ist im Gehäuse (1) versenkt angeordnet, derart, daß seine dem Gehäuse (1) abgewandte Fläche mit einer den Deckel (5) umgebenden Gehäuseoberfläche (24) im wesentlichen bündig ist. Dadurch bilden die umgebende Gehäuseoberfläche (24) und die dem Gehäuse (1) abgewandte Seite des Deckels (5) eine zusammenhängende Oberfläche, auf der das zweite Bauteil (2) bei seiner Bewegung geführt ist. Die erwähnte Gehäuseoberfläche (24) ist ihrerseits wenigstens um die Dicke des zweiten Bauteils (2) gegenüber der übrigen Gehäuseoberfläche auf der betreffenden Seite abgesenkt. Da auch der Mitnehmer (4) des Deckels (5) nicht dicker als das zweite Bauteil (2) ist, ist durch diese Absenkung der Oberfläche (24) die Einrichtung im Gehäuse untergebracht, ohne die Gehäuseabmessungen zu überschreiten.The cover (5) is sunk in the housing (1) such that its surface facing away from the housing (1) is essentially flush with a housing surface (24) surrounding the cover (5). As a result, the surrounding housing surface (24) and the side of the cover (5) facing away from the housing (1) form a coherent surface on which the second component (2) is guided as it moves. The mentioned housing surface (24) is in turn lowered by at least the thickness of the second component (2) compared to the rest of the housing surface on the relevant side. Since the driver (4) of the cover (5) is not thicker than the second component (2), the lowering of the surface (24) means that the device is accommodated in the housing without exceeding the housing dimensions.

Zur drehbaren Lagerung des Deckels (5) weist das Gehäuse (1) eine zur Drehachse (6) drehsymmetrische, etwa durch Ansenken hergestellte, nicht bezeichnete Mantelfläche auf. Der Deckel weist eine zu dieser Mantelfläche kompatible Mantelfläche (26) auf. Mit dieser ist er in der Mantelfläche des Gehäuses (1) radial gelagert. Als drehsymmetrische Flächen haben die genannten Mantelflächen, je nach ihrer Ausbildung in Richtung der Drehachse (6) wenigstens einen Kreis als Grundriß. Der Gehäuseschlitz (7) liegt innerhalb dieses Grundrisses. Der Durchmesser der Mantelflächen ist so bemessen, daß der Führungsschlitz in dem Grundriß wenigstens angenähert nach Art einer (Kreis-) Sehne liegt, d. h. im Bereich seiner Stirnseiten den genannten Grundriß berührt oder nahezu berührt. Dies ergibt bei vorgegebener Lage der Drehachse (6) die geringstmögliche Querabmessung des Deckels (5). Kann die Lage der Drehachse (6) im Rahmen der gewünschten Kraft- bzw. Wegübersetzungen zwischen den Bauteilen variiert werden, so kann auch sie zur Ermittlung der geringstmöglichen Querabmessung des Deckels (5) herangezogen werden. Wird in nicht dargestellter Weise der beschriebenen drehbaren Lagerung, genauer: der Lagerfuge, auch die oben beschriebene Abdichtfunktion übertragen, so ist die überhaupt mögliche minimale Querabmessung des Deckels (5) sichergestellt.For the rotatable mounting of the cover (5), the housing (1) has an outer surface, which is rotationally symmetrical to the axis of rotation (6), for example produced by countersinking. The cover has a jacket surface (26) that is compatible with this jacket surface. With this he is mounted radially in the lateral surface of the housing (1). Depending on their design in the direction of the axis of rotation (6), the lateral surfaces mentioned have, as rotationally symmetrical surfaces, at least one circle as a plan. The housing slot (7) lies within this floor plan. The diameter of the lateral surfaces is dimensioned such that the guide slot in the plan is at least approximately in the manner of a (circular) chord, ie touches or almost touches the plan in the area of its end faces. For a given position of the axis of rotation (6), this results in the smallest possible transverse dimension of the cover (5). If the position of the axis of rotation (6) can be varied within the framework of the desired force or path translations between the components, then it can also be used to determine the smallest possible transverse dimension of the cover (5). If, in a manner not shown, the described rotatable mounting, more precisely: the bed joint, the sealing function described above is also transferred, so the minimum possible transverse dimension of the cover (5) is ensured.

Im Ausführungsbeispiel ist die drehbare Lagerung (Lagerfuge) jedoch von der Dichtfunktion entlastet. Zu diesem Zweck weist das Gehäuse in einer quer zur Drehachse (6) des Deckels (5) liegenden Ebene einen die Mantelfläche einschließenden, nicht bezeichneten Dichtsitz auf, auf dem der Deckel (5) mit einem dazu kompatiblen Dichtsitz (23) aufliegt.In the exemplary embodiment, however, the rotatable mounting (bearing joint) is relieved of the sealing function. For this purpose, the housing has, in a plane lying transversely to the axis of rotation (6) of the cover (5), a sealing seat, not designated, enclosing the lateral surface, on which the cover (5) with a compatible sealing seat (23) rests.

Die Dichtsitze von Gehäuse (1) und Deckel (5) werden von äußeren, zur Drehachse (6) drehsymmetrischen und zueinander kompatiblen äußeren Mantelfläche eingeschlossen, von denen diejenige am Deckel mit (25) bezeichnet ist. Durch die drehsymmetrische Ausbildung dieser äußeren Mantelfläche wird in Ansehung der Trennung von drehbarer Lagerung und Abdichtfunktion die Bauweise mit der geringstmöglichen Querabmessung des Deckels (5) erzielt. Die Dichtsitze sind jeweils an Übergangsflächen im Gehäuse (1) und am Deckel (5) zwischen der äußeren Mantelfläche (z. B. 25) und der drehbaren Lagerung dienenden Mantelfläche (z. B. 26) ausgebildet.The sealing seats of the housing (1) and cover (5) are enclosed by an outer outer surface, which is rotationally symmetrical to the axis of rotation (6) and compatible with one another, of which the one on the cover is designated by (25). Due to the rotationally symmetrical design of this outer lateral surface, the construction with the smallest possible transverse dimension of the cover (5) is achieved in view of the separation of the rotatable bearing and sealing function. The sealing seats are each formed on transition surfaces in the housing (1) and on the cover (5) between the outer circumferential surface (e.g. 25) and the rotatable bearing-serving circumferential surface (e.g. 26).

Die erwähnten Mantelflächen sind als Zylinderflächen und die erwähnten Dichtsitze sind als Stufenflächen zwischen den Zylinderflächen dargestellt. Diese Flächen können aber auch auf jede andere die geforderten Funktionen sicherstellende Art ausgebildet sein.The lateral surfaces mentioned are shown as cylindrical surfaces and the sealing seats mentioned are shown as step surfaces between the cylindrical surfaces. However, these surfaces can also be designed in any other way that ensures the required functions.

Die beschriebene Trennung von drehbarer Lagerung und Abdichtfunktion ermöglicht in nicht dargestellter Weise auch, daß der Deckel statt der umlaufenden Mantelfläche (26) nur an einigen Stellen auf dem gleichen Umfang Lagerpunkte bzw. -flächen aufweist.The described separation of the rotatable bearing and the sealing function also enables, in a manner not shown, that the cover instead of the rotating one The lateral surface (26) has bearing points or surfaces only in a few places on the same circumference.

Insgesamt ist der Deckel (5) als scheibenförmiger Körper ausgebildet, der mit seiner gesamten Dicke im Gehäuse (1) versenkt ist. Auch diese Anordnung dient der bereits erwähnten Unterbringung der Einrichtung im Gehäuse ohne Veränderung der Gesamtabmessungen.Overall, the cover (5) is designed as a disk-shaped body, which is sunk with its entire thickness in the housing (1). This arrangement also serves to accommodate the device in the housing, as already mentioned, without changing the overall dimensions.

Wie Fig. 1 zeigt, liegt auf dem nicht abgesenkten Bereich der Gehäuseoberfläche noch ein weiteres lamellenförmiges Ventilglied (13) auf, welches in nicht näher beschriebener Weise mit Gehäuseöffnungen (11) weitere Einlaßventile (11, 13) bildet und welches das zweite Bauteil (2) in der Draufsicht teilweise abdeckt. In Fig. 2 ist das Ventilglied (13) der Übersichtlichkeit halber weggelassen.As shown in FIG. 1, there is another lamellar valve member (13) on the non-lowered area of the housing surface, which forms further inlet valves (11, 13) with housing openings (11) in a manner not described in detail and which forms the second component (2 ) partially covered in the top view. In Fig. 2 the valve member (13) is omitted for the sake of clarity.

Die in dem Ausführungsbeispiel dargestellte Einrichtung zur Übertragung einer Antriebskraft zwischen zwei Bauteilen funktioniert wie folgt.The device shown in the exemplary embodiment for transmitting a driving force between two components functions as follows.

Das erste Bauteil ist durch Druckbeaufschlagung des Stellglieds (8) über einen nicht näher bezeichneten Druckanschluß aus seiner Endstellung (I) in seine Endstellung (I) verschiebbar und wird bei Druckabfall durch eine nicht näher bezeichnete Rückstellfeder in die Endstellung (I) zurückgeschoben. Bei diesen Verschiebungen überträgt das erste Bauteil (22) auf die Flanke des Führungsschlitzes (20) im Deckel (5) eine Antriebskraft in Umfangsrichtung des Deckels (5), wobei gleichzeitig das Ende (21) des ersten Bauteils (22) in dem Führungsschlitz (20) gleitet. Infolge des Drehmoments, welches die Antriebskraft auf den Deckel (5) ausübt, dreht sich dieser. Dabei nimmt er das zweite Bauteil (2) in dessen Schwenkrichtung (S) mit. Bei der Mitnahme übt der Mitnehmer (4) des Deckels (5) auf die Flanke des Führungsschlitzes (3) eine Umfangskraft auf das zweite Bauteil (2) um dessen Schwenkachse (12) aus, wobei der Mitnehmer (4) gleichzeitig in dem Führungsschlitz (3) gleitet.The first component can be displaced from its end position (I) into its end position (I) by pressurizing the actuator (8) via an unspecified pressure connection and is pushed back into the end position (I) by a return spring (not specified) when the pressure drops. During these displacements, the first component (22) transmits a driving force in the circumferential direction of the cover (5) to the flank of the guide slot (20) in the cover (5), the end (21) of the first component (22) in the guide slot ( 20) slides. As a result of the torque which the driving force exerts on the cover (5), it rotates. He takes the second component (2) in its swivel direction (S). When driving, the driver (4) of the cover (5) exerts a peripheral force on the flank of the guide slot (3) on the second component (2) about its swivel axis (12), the driver (4) simultaneously in the guide slot ( 3) slides.

Es liegt auf der Hand, daß eine in das zweite Bauteil (2) eingeleitete Kraft bei umgekehrtem Ablauf der Funktion entsprechend auf das erste Bauteil (22) übertragen wird.It is obvious that a force introduced into the second component (2) is correspondingly transmitted to the first component (22) when the function is reversed.

Es liegt auf der Hand, daß durch Veränderung des Abstands bzw. der Abstände des Bauteils (22) bzw. des Mitnehmers (4) von der Schwenkachse (6) die Kraft- und Wegübersetzung zwischen dem ersten Bauteil (22) und dem zweiten Bauteil (2) varriierbar ist. Im Ausführungsbeispiel bewegen sich erstes Bauteil (22) und zweites Bauteil (2) gleichsinnig; dies deshalb, weil von der Schwenkachse (12) aus gesehen die Eingriffsstellen zwischen beiden Bauteilen (22, 2) und Deckel (5) diesseits der Drehachse (6) angeordnet sind. Eine gegensinnige Bewegung, d. h. eine Kraft- und Bewegungsumkehr, ergibt sich, wenn die genannten Eingriffstellen, wieder von der Schwenkachse (12) aus gesehen, auf verschiedenen Seiten der Drehachse (6) angeordnet sind.It is obvious that by changing the distance or distances of the component (22) or the driver (4) from the pivot axis (6), the force and displacement ratio between the first component (22) and the second component ( 2) can be varied. In the exemplary embodiment, the first component (22) and the second component (2) move in the same direction; this is because seen from the pivot axis (12), the points of engagement between the two components (22, 2) and cover (5) are arranged on this side of the axis of rotation (6). An opposite movement, i. H. there is a reversal of force and movement if the said engagement points, again seen from the pivot axis (12), are arranged on different sides of the axis of rotation (6).

Der Fachmann erkennt, daß sich der Schutzbereich der vorliegenden Erfindung nicht in dem Ausführungsbeispiel erschöpft, sondern alle Ausgestaltungen erfaßt, deren Merkmale sich den Patentansprüchen unterordnen.Those skilled in the art will recognize that the scope of protection of the present invention is not limited to the exemplary embodiment, but rather encompasses all configurations, the features of which are subordinate to the patent claims.
