Abstract

Vorgeschlagen ist ein schaltbarer Stößel (1) wie ein Tassenstößel. Dieser besteht aus einem Außenkörper (2), in dessen Bohrung (3) ein relativ zu diesem axial beweglicher Innenkörper (4) gesteckt ist. Beide Körper (2, 4) sind im Bereich ihrer Böden (13, 14) von Nocken unterschiedlichen Hubes kontaktierbar. In dem Außenkörper (2) ist konzentrisch ein flacher Ring als Koppelmittel (6) appliziert. Dieser kann für einen Koppelzustand der Körper (2, 4) (großer Ventilhub) abschnittsweise in eine Ringnut (10) am Außenmantel (5) des Innenkörpers (4) verlagert werden, so dass eine sichelartige Eingriffsstruktur vorliegt. Ein derartiger Koppelmechanismus lässt sich u. a. relativ einfach herstellen und besitzt gegenüber bisher ausgeführten Kolbenmechanismen zur Kopplung eine gesteigerte Belastbarkeit.Proposed is a switchable plunger (1) as a bucket tappet. This consists of an outer body (2), in the bore (3) a relative to this axially movable inner body (4) is inserted. Both bodies (2, 4) can be contacted by cams of different stroke in the region of their bottoms (13, 14). In the outer body (2), a flat ring is applied concentrically as coupling means (6). This can for a coupling state of the body (2, 4) (large valve lift) partially in an annular groove (10) on the outer casing (5) of the inner body (4) are displaced so that a sickle-like engagement structure is present. Such a coupling mechanism can u. a. relatively easy to manufacture and has compared to previously executed piston mechanisms for coupling increased load capacity.
