Abstract

Official abstract text for this publication.

This turbocharger (1A) is provided with: a rotating shaft (4); a turbine wheel (2); a compressor wheel (3); a bearing housing (6) provided with journal bearings (5A, 5B) for rotatably supporting a shaft (4), and a thrust bearing (8) for supporting the rotating shaft (4) in the center axis (C) direction thereof; and a turbine housing (31) in which the turbine wheel (2) is accommodated. A fluid supply section (70A) for supplying a fluid to the turbine wheel (2) is provided within the turbine housing (31) and said fluid presses the turbine wheel (2) toward a first end (4a) side.

First claim

Opening claim text (preview).

The invention claimed is: 1. A turbocharger comprising: a rotating shaft which extends along a center axis; a turbine wheel which is provided on a first end side of the rotating shaft; a compressor wheel which is provided on a second end side of the rotating shaft; a bearing housing which includes a radial bearing for rotatably supporting the rotating shaft and a thrust bearing for supporting the rotating shaft in the center axis direction; a turbine housing which receives the turbine wheel; and a fluid supply section for supplying a fluid which presses the turbine wheel toward the first end side to the turbine wheel in the turbine housing, wherein the fluid supply section extracts a gas from an upstream side of the turbine wheel in a flow direction of the gas supplied to the turbine wheel, and supplies the gas to a back surface of the turbine wheel on the second end side, wherein the bearing housing has a lubricating oil feed path for supplying a lubricating oil to at least the radial bearings from an oil feed pipe connection port which extends radially inward of the bearing housing from an outer circumferential surface of the bearing housing, wherein the fluid supply section is provided directly adjacent and parallel to the oil feed pipe connection port and the lubricating oil feed path in the bearing housing, and wherein the lubricating oil is capable to being heated by the heat of the fluid supplied to the turbine wheel, such that the viscosity is capable to being lowered.
