| description | A sliding piston cartridge (50)for a turbocharger (20) that is insertable into a bore (44) in the turbine housing (38) as a unit and that includes all of the components of a sliding piston type variable nozzle. The sliding piston cartridge comprises a carrier (52) having a tubular portion that interfaces with the bore of the turbine housing. A sliding piston (62) is disposed within the carrier and makes sliding contact therewith. Vanes (58) are mounted on or formed as a part of the carrier at its upstream end, the vanes extending across a turbine nozzle. The piston slides between a closed position and an open position relative to the carrier. The tubular portion of the carrier can include openings (66) that are progressively uncovered by the piston as it moves toward the open position, to allow additional flow to enter the turbine wheel without passing through the vanes.
Cartouche à piston coulissant (50) pour turbocompresseur (20), s'insérant d'un bloc dans un alésage (44) de la volute de turbine (38) et comprenant tous les composants d'une tuyère variable du type à piston coulissant. La cartouche de piston coulissant comprend un élément porteur (52) dont la partie tubulaire est en contact avec l'alésage dans la volute de turbine. Un piston coulissant (62) est disposé à l'intérieur de l'élément porteur avec lequel il est en contact coulissant. Les aubes (58) sont montées sur l'extrémité aval de l'élément porteur, dont elles font partie, et traversent une tuyère de turbine. Le piston coulisse entre une position fermée et une position ouverte par rapport à l'élément porteur. La partie tubulaire de l'élément porteur peut présenter des ouvertures (66) qui sont découvertes progressivement au fur et à mesure que le piston se déplace vers la position d'ouverture, ce qui permet à un flux d'air supplémentaire de pénétrer dans la roue de turbine sans traverser les aubes. |
