Title
(DE) Verdichter für eine Aufladevorrichtung einer Brennkraftmaschine und Aufladevorrichtung für eine Brennkraftmaschine
Abstract
(DE)

Die Erfindung betrifft einen Verdichter (30) für eine Aufladevorrichtung (1) einer Brennkraftmaschine. Stromaufwärts vor dem Verdichterrad (13) ist ein Irisblendenmechanismus (50) angeordnet. Es ist ein Aktuator (61) vorgesehen, der mechanisch mit einem Verstellring (53) des Irisblendenmechanismus (50) zum Übertragen eines Drehmoments einer Aktuatorwelle (62) auf den Verstellring (53) zum Verdrehen des Verstellrings (53) gekoppelt ist. An der Aktuatorwelle (62) ist exzentrisch ein verschwenkbarer Koppelstift (64) angeordnet, der eine entlang einer Längsachse des Koppelstifts (64) verschiebbare Lagerbuchse (66) aufweist. Die Lagerbuchse (66) ist zwischen zwei Fingern (67) eines Stellhebels (53a) des Verstellrings (53) verschiebbar entlang der Finger (67) an den Fingern (67) gelagert. Eine äußere Kontaktoberfläche (71) ist der Lagerbuchse (66) sphärisch ausgebildet. Innere Kontaktoberflächen (72) der beiden Finger (67) sind korrespondierend zu der sphärischen äußeren Kontaktoberfläche (71) der Lagerbuchse (66) zylindrisch ausgebildet und stehen in Gleitkontakt mit der äußeren Kontaktoberfläche (71) der Lagerbuchse (66). Die Erfindung betrifft auch eine Aufladevorrichtung (1). embedded image
