Abstract

A roller slide (4) has a central passage channel (6) and a slide ring (9), which partially defines an intake channel (8). When the passage channel opens the intake channel, the slide ring is lifted off the outer contour (10) of the rotary slide by a spring (12). The slide ring is located in a stepped bore (7) in a housing (3), and is supported on the smaller bore section (7'). The ring has a radial flange (13) in the larger bore section (7''). The spring is located between the step (14) of the bore and the flange.

Description

Die Erfindung bezieht sich mit dem Oberbegriff des Patentanspruches 1 auf eine Walzenschieber-Anordnung, insbesondere zur Ladungssteuerung einer Brennkraftmaschine, die einen in einem Gehäuse spielbehaftet drehbeweglich angeordneten Walzenschieber umfasst mit einem quer zur Drehachse im wesentlichen gemittelt angeordneten Durchgangskanal, und einem stromauf des Durchgangskanals in einer Ausnehmung des Gehäuses angeordneten, einen Zuströmkanal abschnittsweise begrenzenden Gleitring zur gleitbeweglich dichten Auflage auf der Außenkontur des Walzenschiebers, wobei der Gleitring in der Ausnehmung unter Zwischenschaltung eines Dichtelementes beweglich angeordnet ist.The invention relates to a preamble of claim 1 Roller valve arrangement, in particular for charge control of an internal combustion engine, the one rotatably arranged in a housing with play Roller slide essentially comprises averaged transversely to the axis of rotation arranged through channel, and an upstream of the through channel in a recess of the housing arranged, an inflow channel in sections delimiting slide ring for slidably tight support on the outer contour of the roller valve, the slide ring in the recess with the interposition a sealing element is movably arranged.

Eine derartige Walzenschieber-Anordnung ist beispielsweise aus der DE 198 15 739 A1 bekannt, wobei der Gleitring in der Ausnehmung des Gehäuses unter Zwischenschaltung eines O-Ringes als Dichtelement beweglich angeordnet ist. An diesem gegenüber dem Zuströmkanal abgedichteten Gleitring wirkt insbesondere in einer den Zuströmkanal verschließenden Stellung des Walzenschiebers der auf diesen stromab wirkende Ansaug-Unterdruck über das Laufspiel bzw. den Umfangsspalt zwischen Walzenschieber und Gehäuse. Der somit bei Ansaug-Unterdruck von einem Überdruck im Zuströmkanal kolbenartig beaufschlagte Gleitring wird dadurch in nachteiliger Weise über jede Drehung des Walzenschiebers gegen dessen Außenumfang dichtend angepresst. Such a roller valve arrangement is, for example, from DE 198 15 739 A1 known, the sliding ring in the recess of the housing with interposition an O-ring is movably arranged as a sealing element. At this seal sealed against the inflow channel acts in particular in a position of the roller valve closing the inflow channel this downstream suction vacuum via the running clearance or the circumferential gap between the roller valve and the housing. The therefore with suction vacuum piston ring acted upon by an overpressure in the inflow channel is thereby adversely opposed to any rotation of the plunger the outer circumference pressed tight.

Die damit erhöhte Reibung zwischen Walze und Gleitring führt zu erhöhten Verstellkräften sowie zu einem starken Verschleiß.The increased friction between the roller and slide ring leads to increased adjustment forces as well as heavy wear.

Der Erfindung liegt die Aufgabe zugrunde, die Walzenschieber-Anordnung dahingehend zu verbessern, dass der Gleitring im wesentlichen lediglich in Sperrstellung des Walzenschiebers gegenüber dem Zuströmkanal dicht anliegt.The invention is based on the object, the roller valve arrangement to improve that the slide ring essentially only in the locked position of the roller valve lies tight against the inflow channel.

Diese Aufgabe ist mit dem Patentanspruch 1 dadurch gelöst, dass der Gleitring bei den Zuströmkanal offen steuernden Durchgangskanal mittels einer Einrichtung von der Außenkontur des Walzenschiebers entfernt bzw. abgehoben angeordnet ist.This object is achieved with claim 1 in that the slide ring at the through channel openly controlling the inflow channel by means of a device from the outer contour of the roller slide is removed or lifted off.

Damit sind in vorteilhafter Weise aufgrund der verringerten Reibung reduzierte Verstellkräfte erreicht und außerdem der Verschleiß zwischen Walzenschieber und Gleitring verringert.This advantageously means reduced adjustment forces due to the reduced friction reached and also the wear between the roller valve and Slip ring reduced.

Eine baulich vorteilhafte Ausgestaltung der Anordnung ist dadurch erreicht, dass die Ausnehmung im Gehäuse als eine Stufenbohrung gestaltet ist mit einem dem Walzenschieber zugewandten Bohrungsabschnitt von kleinem Durchmesser und dass der Gleitring im Bereich des Bohrungsabschnittes von großem Durchmesser einen Radialflansch aufweist, wobei zwischen dem Absatz der Stufenbohrung und dem Radialflansch eine Einrichtung zum gesteuerten Abheben des Gleitringes vom Walzenschieber angeordnet ist.A structurally advantageous embodiment of the arrangement is achieved in that the Recess in the housing is designed as a stepped bore with a roller valve facing bore section of small diameter and that the slide ring in the area of the large diameter bore section Has radial flange, between the shoulder of the stepped bore and the Radial flange a device for controlled lifting of the slide ring from the roller valve is arranged.

Die vorbeschriebene Ausgestaltung ist bezüglich baulicher Einfachheit weiter dahin unterstützt, dass als Einrichtung ein Federelement dient. Dieses kann eine Ring-Wellfeder oder eine Tellerfeder sein oder auch eine Ringfeder aus einem Elastomer.The above-described design is further gone in terms of structural simplicity supports that a spring element serves as a device. This can be a ring wave spring or a plate spring or a ring spring made of an elastomer.

Wesentlich für ein sicheres Ansprechen auf Druckunterschiede des Gleitringes ist die Gestaltung des reibungsarmen Dichtelementes. In weiterer Ausgestaltung der Erfindung wird hierfür vorgeschlagen, dass das Dichtelement ein Lippen-Dichtring ist, an dessen in den Bohrungsabschnitt von großem Durchmesser der Gehäuse-Ausnehmung einpressbaren Haltering eine radial einwärts gerichtete Dichtlippe angeordnet ist, die mit der zuströmseitigen Stirnseite des Gleitringes dicht zusammenwirkt. It is essential for a reliable response to pressure differences in the slide ring the design of the low-friction sealing element. In a further embodiment of the For this purpose, the invention proposes that the sealing element be a lip sealing ring is in the bore portion of large diameter of the housing recess press-in retaining ring arranged a radially inward sealing lip is that cooperates closely with the upstream end face of the slide ring.

Der Vorteil dieses Lippen-Dichtringes ist, dass die ringförmige Dichtlippe bei Bewegungen des Gleitringes durch Biegeverformung dem bewegten Gleitring folgt bei kleinstmöglicher Reibung der Dichtlippe auf der Stirnseite des Gleitringes.The advantage of this lip sealing ring is that the ring-shaped sealing lip when moving of the sliding ring by bending deformation follows the moving sliding ring smallest possible friction of the sealing lip on the face of the slide ring.

Weiter ist aus der Zeichnung ersichtlich, dass zwischen dem Absatz 14 der Stufenbohrung 7 und dem Radialflansch 13 eine Einrichtung 12 zum gesteuerten Abheben des Gleitringes 9 vom Walzenschieber 4 angeordnet ist.As can be seen from FIGS. 1 and 2, the recess 7 in the housing 3 is one Stepped bore designed with a bore section facing the roller valve 4 7 'of small diameter, the sliding ring 9 in the region of the bore section 7 "of large diameter has a radial flange 13. It can also be seen from the drawing that between paragraph 14 of the stepped bore 7 and the radial flange 13 a device 12 for controlled lifting the slide ring 9 is arranged by the roller valve 4.

Eine kleinbauende Einrichtung 12 ist mittels eines Federelementes erzielt. Dieses kann als eine Ring-Wellfeder oder als eine Tellerfeder ausgebildet sein. Weiter kann die Einrichtung bzw. das Federelement 12 auch als eine Ringfeder aus einem Elastomer gestaltet sein.A small-sized device 12 is achieved by means of a spring element. This can be designed as an annular wave spring or as a plate spring. Can continue the device or the spring element 12 also as an annular spring from a Be designed elastomer.
