Abstract

Vorgeschlagen ist ein schaltbares Abstützelement (1) für einen Ventiltrieb einer Brennkraftmaschine, mit einem über dessen äußere Mantelfläche (2) in einer Aufnahme einer Brennkraftmaschine anordenbaren Außenteil (3), in dessen Bohrung (4) ein axial bewegliches Innenelement (5) mit einem Kopf (6) zur einenendigen Abstützung eines Nockenfolgers und mit einer hydraulische Spielausgleichseinrichtung (7) verläuft, wobei das Außenteil (3) und das Innenelement (5) in einer axial entfernten Relativstellung über Koppelmittel (8) wahlweise miteinander koppelbar sind. Das Abstützelement (1) hat erfindungsgemäß eine einflutige Versorgung der Koppelmittel (8) und der Spielausgleichseinrichtung (7).
