    摘要： A turbocharger according to one embodiment of this invention includes: a rotation shaft; a compressor impeller; a compressor housing; a bearing housing connected to the compressor housing and configured to define a diffuser flow path between the bearing housing and the compressor housing; a thrust plate configured to support the rotation shaft in an axial direction; an insert component configured to retain the thrust plate between the insert component and a protruding wall portion in the bearing housing; a snap ring configured to be inserted in a first circumferential groove formed in an inner peripheral wall surface of the bearing housing, to thereby fix the insert component in a state in which the insert component is pressed against the thrust plate; and a diffuser component having a diffuser surface extending along a direction orthogonal to an axis of the rotation shaft between the inner peripheral wall surface of an end portion of the bearing housing on one side thereof and an outer peripheral edge of the compressor impeller.

    摘要： A turbocharger according to an embodiment of the present invention includes a rotating shaft, a compressor, a turbine, a compressor-side floating bearing and a turbine-side floating bearing that rotatably support the rotating shaft, and a bearing housing that houses the compressor-side floating bearing and the turbine-side floating bearing, the bearing housing being internally provided with a turbine-side oil feeding passage through which oil to be fed to the turbine-side floating bearing flows and a compressor-side oil feeding passage through which oil to be fed to the compressor-side floating bearing flows. A ratio of an oil feeding pressure for oil at an outlet of the compressor-side oil feeding passage to an oil feeding pressure for oil at an outlet of the turbine-side oil feeding passage is configured to be higher than 1.0 and lower than 1.5.

    摘要： An object is to provide a floating bush bearing device including a circumferential groove over the entire circumference of an outer peripheral surface of a floating bush while ensuring that a pressing force is applied by lubricant oil to the floating bush to reduce oscillation, as well as a turbocharger provided with the bearing device. A floating bush bearing device includes: a rotary shaft disposed rotatably inside a bearing hole of a casing; a floating bush surrounding the rotary shaft; an oil-feed hole of lubricant oil having an opening on an inner peripheral surface of the bearing hole; a plurality of communication holes formed on the floating bush, each extending between an inner peripheral surface and an outer peripheral surface of the floating bush, and disposed at intervals in a circumferential direction of the floating bush; and a circumferential groove formed on the outer peripheral surface of the floating bush or the inner peripheral surface of the bearing hole and extending over an entire circumference of the outer peripheral surface of the floating bush or the inner peripheral surface of the bearing hole, the circumferential groove passing through openings of the plurality of communication holes or facing the openings of the plurality of communication holes. The circumferential groove has a cross-sectional area which varies in accordance with a circumferential position.
