Abstract
Vorgeschlagen ist ein auf unterschiedliche Hübe für wenigstens ein Gaswechselventil umschaltbarer Schlepphebel (1). Dieser besteht aus einem Innenhebel (4) und einem relativ zu diesem verschwenkbeweglichen, gabelförmigen Außenhebel (2). Dabei sind einfach aufgebaute Koppelmittel zur Kopplung der Hebel (4, 2) auf einen großen Ventilhub vorgeschlagen, welche aus einem orthogonal zur Hebellängsachse im Innenhebel (4) verlaufenden Schieber (15) bestehen, der wahlweise in Eingriff mit einer Querachse (13) zur gemeinsamen Lagerung der Hebel (4, 2) bringbar ist. Die Querachse (13) ist drehfest mit dem Außenhebel (2) verbunden, wohingegen der Innenhebel (4) verdrehbeweglich gegenüber der Querachse (13) ist.
