20120121400 | COMPRESSOR OF EXHAUST GAS TURBOCHARGER - A compressor of an exhaust gas turbocharger has an inlet slit, an outlet slit and the recirculation passage can formed at the same time when the compressor housing assembled. Ease of assembly and the reduction of the production cost is achieved. The structure of the inlet slit, the outlet slit and the recirculation passage can be compact and can be easily adjusted. Noises generated in the compressor impeller can be reduced without providing a noise insulation cover. | 05-17-2012 |
20120148391 | CENTRIFUGAL COMPRESSOR - A centrifugal compressor is equipped with a resin housing, that is made in a manner such that compression efficiency is not lost and merits such as weight and cost reduction are not cancelled out. The turbo charger housing comprises a volute section, a channel formation section, and an impeller that is fixed in the center of the channel formation section to a rotating shaft. An annular shroud is disposed in a recess formed on the inner wall of the channel formation section. The annular shroud forms the outer walls of a channel and a diffuser for compressed gas. The edge of the annular shroud spaced from a partition wall, which forms a portion of a bearing housing. If the resin housing undergoes thermal deformation, the dimensions of a gap between the annular shroud and the curved profile of a blade is maintained. | 06-14-2012 |

20140125208 | MOTOR ROTOR STRUCTURE FOR ELECTRIC TURBO CHARGER AND METHOD OF ASSEMBLING SAME - A motor rotor structure for an electric turbo charger is manufactured at low cost with good quality by fixedly fitting, over a shaft, a rotor core having electromagnetic steel sheets pre-formed as an integrated stack. The rotor structure includes a rotor core which is rotated by a magnetic field formed by a stator in a housing; a shaft configured to rotate a compressor impeller and the rotor core together; and a bearing supporting the shaft. The rotor includes the rotor core including the electromagnetic steel sheets; a stopper portion formed at an intermediate portion of the shaft to restrict axial movement of the rotor core; and a pressing unit which presses the rotor core fitted over the shaft against the stopper portion. The pressing unit prevents a circumferential phase shift between the shaft and the rotor core by a pressing force thereof. | 05-08-2014 |
20140147306 | STRUCTURE AND METHOD FOR ADJUSTING BALANCE OF TURBOCHARGING DEVICE INCORPORATING ELECTRIC MOTOR - An object is to increase portions (increase the amount of correction), where the rotational balance of a rotary shaft of a turbocharging device incorporating an electric motor is adjusted, and to maintain sufficient motor driving force even under a high temperature condition. In a balance adjusting structure for the turbocharging device incorporating an electric motor, a rotor core | 05-29-2014 |
