Abstract
Official abstract text for this publication.
A turbocharger includes a compressor housing including a scroll chamber, and a seal plate assembled to the compressor housing. The compressor housing and the seal plate define an intake passage. The seal plate includes a plate-side connecting portion in contact with the compressor housing. The radius of curvature of a wall surface of the scroll chamber of the compressor housing, in a section including a compressor rotational axis, is increased in a direction toward an outlet located on the downstream side of the scroll chamber in an intake air flow direction. The plate-side connecting portion protrudes in a direction along the compressor rotational axis. The radius of curvature of an inner surface of the seal plate continuous with the scroll chamber of the intake passage, in the section including the compressor rotational axis, is increased in the direction toward the outlet of the scroll chamber.
First claim
Opening claim text (preview).
What is claimed is: 1 . A turbocharger comprising: a compressor housing including a scroll chamber; and a seal plate assembled to the compressor housing, the compressor housing and the seal plate defining an intake passage, the seal plate including a plate-side connecting portion in contact with the compressor housing, a radius of curvature of a wall surface of the scroll chamber of the compressor housing, in a section including a compressor rotational axis, being increased in a direction toward an outlet located on a downstream side of the scroll chamber in an intake air flow direction, the plate-side connecting portion protruding in a direction along the compressor rotational axis, and a radius of curvature of an inner surface of the seal plate continuous with the scroll chamber of the intake passage, in the section including the compressor rotational axis, being increased in the direction toward the outlet of the scroll chamber.
