A turbocharger includes a semi-floating metal (6). The semi-floating metal (6) is provided with a supply opening (61c) configured to supply oil to an inner bearing section. The turbocharger is provided with: an oil supply path (FL) which extends from insid...

It is intended to reduce friction loss during low-speed rotation and increase supercharging pressure in the low-speed rotational range of a turbocharger by providing a pressure-receiving section, which generates pressure by catching the flow of lubricating...

The device i.e. turbocharger (1), has a shaft (4) rotatably supported at a radial slide bearing (5), and a flow opening (9) formed for supplying and/or discharging fluid to a shaft bearing area (7), where the bearing has an annular groove. The shaft has ou...

An epicyclic gear assembly (36) of a gas turbine engine (10) comprises a journal bearing, the journal bearing (44) includes a central body (55) having first passageway (56) and a filter module (58). The central body (55) extends axially and is adapted to b...

A turbocharger rotor has a turbine wheel (12) and shaft (32), a compressor wheel (14) and adapter (50) and a separate thrust runner clamped (16) together by a fastener rod (18). The adapter (50) is piloted on the shaft (32) and the thrust runner (16) is pi...

The invention relates to a turbocharger for an internal combustion engine, in which a bearing having excellent abrasion resistance without generating a black corrosion product in a high-temperature oil environment is provided. As bearing materials of a tur...
