涡轮增压器
摘要：
提供了一种涡轮增压器(10)，其包括压缩机壳体(13)以及组装至该压缩机壳体的密封板(14)，压缩机壳体(13)包括涡形室(16e)。压缩机壳体与密封板限定进气通道(16)。密封板包括与压缩机壳体相接触的板侧连接部(14d)。压缩机壳体的涡形室的壁表面的、在包含压缩机旋转轴线的截面中的曲率半径沿朝向出口的方向增大，该出口位于涡形室的沿进气流方向的下游侧。板侧连接部在沿着压缩机旋转轴线的方向上突出。密封板的与进气通道的涡形室相连续的内表面的、在包含压缩机旋转轴线的截面中的曲率半径沿朝向涡形室的出口的方向增大。
摘要（英）：

A turbocharger (10) includes a compressor housing (13) including a scroll chamber (16e), and a seal plate (14) assembled to the compressor housing. The compressor housing and the seal plate define an intake passage (16). The seal plate includes a plate-side connecting portion (14d) 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.
