Abstract

Vorgeschlagen ist ein schaltbarer Stößel (1) zur direkten Übertragung eines Nockenhubes auf eine Stößelstange. Erfindungsgemäß ist eine als Lost-Motion-Feder verwendete Schraubendruckfeder (15) zur Beaufschlagung des Innenelements (4) axial aus einem Gehäuse (2) verlagert. Hierfür hat das Innenelement (4) einen aus dem Gehäuse (2) heraus geführten Ansatz (15a), welcher von der Schraubendruckfeder (15) umschlossen ist.
Diese Maßnahme trägt zur Minimierung der Gesamtmasse des schaltbaren Stößels (1) bei, da die Baulänge des Gehäuses (2) verkürzt ist.
