Description
また、本発明の第二態様に係る排ガスタービン過給機は、前記のいずれかの軸流タービンのラビリンスシール装置を備えるとともに、前記タービン軸に圧縮機が同軸的に設けられ、前記排ガスのエネルギーにより該圧縮機を回転駆動して内燃機関の吸入ガスを過給することを特徴とする。 An exhaust gas turbine supercharger according to the second aspect of the present invention includes any one of the labyrinth seal devices for an axial flow turbine described above, and a compressor is coaxially provided on the turbine shaft, and the energy of the exhaust gas. Thus, the compressor is rotated to supercharge the intake gas of the internal combustion engine.
図2にも示すように、ガスラビリンスシールGLを構成するラビリンス部材22は、その外周面22aが排ガス通路13(排ガス出口ケーシング12)の内周面13aに対して段差を発生させないように排ガス通路13内に露呈しており、排ガス出口ケーシング12とともに排ガス通路13を形成している。また、ラビリンス部材22は、排ガス出口ケーシング12との間に間隙状のシールガス放出通路26を介して隣接するように軸受台2に固定されている。 As shown in FIG. 2, the labyrinth member 22 constituting the gas labyrinth seal GL has an exhaust gas passage so that the outer peripheral surface 22a does not generate a step with respect to the inner peripheral surface 13a of the exhaust gas passage 13 (exhaust gas outlet casing 12). The exhaust gas passage 13 is formed together with the exhaust gas outlet casing 12. Further, the labyrinth member 22 is fixed to the bearing block 2 so as to be adjacent through between gap-shaped seal gas discharge passage 26 between the exhaust gas outlet casing 12.
ガスラビリンスシールGLを通過した後のシールガスは集気室30(図2参照)に流れ、さらに脱気通路31を経てシールガス放出通路26に流れ、排ガス通路13内に放出される。このようにシールガスが排ガス通路13内に放出される位置は、タービン軸4の軸方向で、タービンディスク6とラビリンス部材22との隣接部(隙間G1)よりも下流側の位置となる。 The seal gas after passing through the gas labyrinth seal GL flows into the air collecting chamber 30 (see FIG. 2), further flows through the deaeration passage 31 to the seal gas discharge passage 26, and is discharged into the exhaust gas passage 13. Thus, the position where the seal gas is discharged into the exhaust gas passage 13 is a position downstream of the adjacent portion (gap G1) between the turbine disk 6 and the labyrinth member 22 in the axial direction of the turbine shaft 4.
