COUPLING DEVICE FOR A VALVE-ACTUATING DEVICE
(FR)
DISPOSITIF DE COUPLAGE POUR UN DISPOSITIF D’ACTIONNEMENT DE SOUPAPES
(DE)
KOPPLUNGSVORRICHTUNG FÜR EINE VENTILBETÄTIGUNGSVORRICHTUNG
Abstract:
(EN)
The present invention relates to a coupling device for a valve-actuating device for actuating at least one valve of a reciprocating machine having variable valve lift, in particular for a valve-actuating device of a reciprocating internal combustion engine, to a valve-actuating device and to a reciprocating machine, the coupling device comprising a first coupling element, a second coupling element and a blocking means. The first coupling element and the second coupling element can be displaced relative to one another at least within defined boundaries along a first axis, it being possible for the blocking means to block the relative displacement of the two coupling elements with respect to one another along the first axis at least in a first direction. The blocking means comprises a blocking element, which can be rotated about the first axis in the circumferential direction at least in a defined region, the relative displacement of the two coupling elements along the first axis being blocked at least in the first direction if the blocking element is in a blocking position.
(FR)
La présente invention concerne un dispositif de couplage pour un dispositif d’actionnement de soupapes pour l’actionnement d’au moins une soupape d’un moteur à piston avec une levee de soupape variable, en particulier pour un dispositif d’actionnement de soupapes d’un moteur à combustion interne à piston, un dispositif d’actionnement de soupapes et un moteur à piston, le dispositif de couplage comprenant un premier élément de couplage, un deuxième élément de couplage et un dispositif de verrouillage. Le premier élément de couplage et le deuxième élément de couplage peuvent être déplacés l’un par rapport à l’autre au moins dans des limites définies le long d’un premier axe, le déplacement relatif entre les deux éléments de couplage le long du premier axe pouvant être bloqué dans au moins une première direction au moyen du dispositif de verrouillage. Le dispositif de verrouillage comprend un élément de verrouillage pouvant au moins être tourné dans la direction périphérique autour du premier axe dans une zone définie, le déplacement relatif entre les deux éléments de couplage le long du premier axe étant bloqué au moins dans la première direction lorsque l’élément de verrouillage se trouve dans une position de blocage.
(DE)
Die vorliegende Erfindung betrifft eine Kopplungsvorrichtung für eine Ventilbetätigungsvorrichtung zur Betätigung wenigstens eines Ventils einer Hubkolbenmaschine mit veränderlichem Ventilhub, insbesondere für eine Ventilbetätigungsvorrichtung einer Hubkolbenbrennkraftmaschine, eine Ventilbetätigungsvorrichtung und eine Hubkolbenmaschine, wobei die Kopplungsvorrichtung ein erstes Kopplungselement, ein zweites Kopplungselement und eine Sperreinrichtung aufweist. Das erste Kopplungselement und das zweite Kopplungselement sind zumindest innerhalb definierter Grenzen entlang einer ersten Achse relativ zueinander verschiebbar, wobei mittels der Sperreinrichtung die Relativverschiebung der beiden Kopplungselemente zueinander entlang der ersten Achse zumindest in eine erste Richtung blockierbar ist. Die Sperreinrichtung weist ein zumindest in einem definierten Bereich in Umfangsrichtung um die erste Achse drehbares Sperrelement auf, wobei die Relativverschiebung der beiden Kopplungselemente entlang der ersten Achse zumindest in die erste Richtung blockiert ist, wenn sich das Sperrelement in einer Blockier-Position befindet.
