Title (EN) TURBOCHARGER FOR AN INTERNAL COMBUSTION ENGINE
(FR) TURBOCOMPRESSEUR POUR UN MOTEUR À COMBUSTION INTERNE
(DE) TURBOLADER FÜR EINE BRENNKRAFTMASCHINE
Abstract:
(EN) The invention relates to a turbocharger (1) for an internal combustion engine, which has a bearing housing (41), in which a rotor shaft (14) is rotatably mounted; a compressor (30) having a compressor wheel (13), which is arranged for conjoint rotation on the rotor shaft (14); a fresh air supply duct (36) for guiding a fresh air mass flow (FM) onto the compressor wheel (13), wherein the fresh air supply duct (36) has a first flow cross-section (A1) upstream of the compressor wheel (13); and a flow control device (50), which is adjustable between an open position, in which the first flow cross-section (A1) is released, and a closed position, in which the first flow cross-section (A1) is reduced to a second flow cross-section (A2); wherein the flow control device (50) is fluidically coupled to a compressor duct of the compressor (30) downstream of the compressor wheel (13), such that the flow control device (50) is adjusted as a function of a pressure prevailing in the compressor.
(FR) L'invention concerne un turbocompresseur (1) pour un moteur à combustion interne, comprenant : - un logement de palier (41) dans lequel un arbre de rotor (14) est monté de manière rotative ; - un compresseur (30) doté d'une roue de compresseur (13), laquelle est disposée de manière solidaire en rotation sur l'arbre de rotor (14) ; - un conduit d'amenée d'air frais (36) servant à guider un flux massique d'air frais (FM) vers la roue de compresseur (13), le conduit d'amenée d'air frais (36) présentant une première section transversale d'écoulement (A1) en amont de la roue de compresseur (13) ; et - un dispositif de régulation d'écoulement (50) qui peut être déplacé entre une position ouverte dans laquelle la première section transversale d'écoulement (A1) est dégagée et une position fermée dans laquelle la première section transversale d'écoulement (A1) est réduite à une deuxième section transversale d'écoulement (A2) ; le dispositif de régulation d'écoulement (50) étant accouplé fluidiquement à un conduit du compresseur (30) en aval de la roue de compresseur (13), de sorte que le dispositif de régulation d'écoulement (50) soit réglé en fonction d'une pression régnant dans le conduit de compresseur.
(DE) Die Erfindung betrifft einen Turbolader (1) für eine Brennkraftmaschine, aufweisend - ein Lagergehäuse (41), in dem eine Läuferwelle (14) drehbar gelagert ist; - einen Verdichter (30) mit einem Verdichterrad (13), welches drehfest auf der Läuferwelle (14) angeordnet ist; - einen Frischluftzuführkanal (36) zum Leiten eines Frischluftmassenstroms (FM) auf das Verdichterrad (13), wobei der Frischluftzuführkanal (36) einen ersten Strömungsquerschnitt (A1) stromaufwärts vor dem Verdichterrad (13) aufweist; und - eine Strömungsregelungsvorrichtung (50), die zwischen einer Offenstellung, in welcher der erste Strömungsquerschnitt (A1) freigegeben ist, und einer Schließstellung, in welcher der erste Strömungsquerschnitt (A1) auf einen zweiten Strömungsquerschnitt (A2) verringert ist, verstellbar ist; wobei die Strömungsregelungsvorrichtung (50) mit einem Verdichterkanal des Verdichters (30) stromabwärts des Verdichterrads (13) fluidisch gekoppelt ist, so dass die Strömungsregelungsvorrichtung (50) in Abhängigkeit eines in dem Verdichterkanal vorherrschenden Drucks verstellt wird.
