Abstract
A turbocharger for an internal combustion engine, the turbocharger being supported by hydrostatic bearings in both a radial and an axial direction by a compressed air supplied from a compressor of the turbocharger and boosted in pressure by a separate boost pump to a high enough pressure to support the rotor of the turbocharger.
Claims3
A turbocharger for an internal combustion engine comprising:
- a compressor to compress air for burning in the internal combustion engine;
- a turbine to drive the compressor using hot gas exhaust from the internal combustion engine;
- a rotor connected between the compressor and the turbine of the turbocharger;
- first and second hydrostatic bearings to rotatably support the rotor in a radial direction;
- a boost compressor having an inlet connected to an outlet of the compressor and an outlet connected to the first and second hydrostatic bearings to support the rotor;
- and,
- the boost compressor increasing a pressure of the compressed air from the compressor to a higher pressure to support the rotor.
