Abstract

Vorgeschlagen ist eine Baueinheit (1) eines Ventiltriebs einer Brennkraftmaschine mit hydraulisch variabler Gaswechselventilbetätigung, umfassend ein Gehäuse (2) mit einer Ausnehmung (3), ein fest darin eingepasstes Nehmergehäuse (4) und einen in einer Bohrung (5) des Nehmergehäuses axialbeweglich gelagerten Nehmerkolben (6), der einerseits mit einem Gaswechselventil (9) zusammenwirkt und andererseits eine in der Bohrung verlaufende Nehmerkammer (10) begrenzt, wobei das durch die Wandung (25) der Ausnehmung radial ausgerichtete Nehmergehäuse eine einem Boden (19) der Ausnehmung zugewandte Stirnseite (18) mit einer Dichtfläche (27) aufweist, die zumindest mittelbar gegen den Boden verspannt ist. Dabei soll im Spannungsfluss zwischen der Stirnseite und dem Boden zumindest ein Spaltausgleichselement mit vorbestimmter axialer Verformbarkeit zur Erzielung einer wenigstens nahezu vollständigen Dichtwirkung der Dichtfläche angeordnet sein.
