Description
Claims (5)
- 排ガス・ターボチャージャの軸受ハウジング(4)を密封するための装置(D)であって、
この軸受ハウジングから、ロータ(R)が、ターボチャージャの、マスフローに曝されるチャンバの中に導かれ、
この装置は、
ロータ(R)の溝(22)の中に配置されたシールリング(5)と;
軸受ハウジング(4)上に配置され、且つ、予荷重が与えられた前記シールリング(5)が、外側に向いた外周面により固定される座面(43)と;
ロータの回転軸(A)の周りに環状に設けられ、径方向に延びる分離間隙(T)と;
を有していて、
この分離間隙は、二つの重なり合う摺動面により規定され、その内の第一の摺動面は、前記シールリング(5)の第一の面(51)上に配置され、第二の摺動面は、前記溝(22)の第一の側面(21)上に配置されている、
装置において、
回転軸(A)の周りに環状に設けられた凹部(26)が、前記溝(22)の第二の側面(23)の中に形成されていること;
この凹部(26)は、ロータ(R)の中に形成された環状のボディ(24)により、径方向外側が規定されていること;
この管状のボディ(24)は、ロータ(R)の外側表面の一部を形成し、且つ外側表面につながり径方向に向けられた環状のエッジ(25)を有していて、この環状のエッジは、前記シールリング(5)が溝の第二の側面(23)に当たった時に生じる摩擦面の寸法を減らす方向に寄与すること;
を特徴とする装置。 - 前記凹部(26)は、前記環状のボディ(24)の中に形成され且つ前記環状のエッジ(25)に至る勾配付きのチャンファ(27)によって規定されること、を特徴とする請求項1に記載の装置。
- 前記勾配付きのチャンファ(27)は、前記溝(22)の底から前記環状のエッジ(25)まで延びていること、を特徴とする請求項2に記載の装置。
- 前記凹部(26)は、前記環状のボディ(24)の中に形成され且つ前記環状のエッジ(25)に至る円筒面(28)によって規定されること、を特徴とする請求項1に記載の装置。
- 前記シールリング(5)を収容する前記溝(22)が、タービンホイール(2)を支持するロータ(R)の上に配置されていること、を特徴とする請求項1から4の何れか一項に記載の装置(D)を有する排ガス・ターボチャージャ。
