내연기관 엔진용 터보차저로서, 상기 터보차저는 컴프레서(11)로부터 공급된 압축공기에 의해 반경 방향 및 축 방향 모두에서 유정압 베어링들(15, 16)에 의해 지지되고, 별개의 부스트 컴프레서(17)에 의해 터보차저의 로터를 지지하기에 충분히 높은 압력으로 압력이 부스팅된다. 터보차저 유정압 베어링들(15, 16)은 와이어 메시 또는 분산형 마찰식 댐퍼들(33, 41)을 사용하여 댐핑된다. A turbocharger for an internal combustion engine, the turbocharger being supported by hydrostatic bearings (15, 16) in both a radial and an axial direction by a compressed air supplied from a compressor (11) of the turbocharger and boosted in pressure by a separate boost compressor (17) to a high enough pressure to support the rotor of the turbocharger. The turbocharger hydrostatic bearings (15, 16) are damped using wire mesh or dispersed friction dampers (33, 41).
