摘要： In an internal combustion engine having an exhaust gas recirculation circuit, the efficiency of a turbocharger is raised in a wide engine rotational speed area and, even when a pressure in an intake circuit is higher than that in an exhaust circuit, an exhaust gas can be circulated. For this purpose, an openable intake throttle valve (12e) is provided on the more upstream side than an exhaust gas circulation position of the intake circuit (12), or a narrow portion (12b) is formed on the exhaust gas circulation position of the intake circuit and an intake bypass circuit (12c) for bypassing the narrow portion is provided. Further, an intake and exhaust bypass circuit (20) for connecting the intake circuit to the exhaust circuit (16) is provided. Then, the opening degree of the intake throttle valve or intake bypass circuit and the opening degree of the intake and exhaust bypass circuit are adjusted so as to set the pressure at the exhaust gas circulation position of the intake circuit to be lower than that in an exhaust manifold (16a).

摘要： A turbocharger as a turbo machine includes: a compressor impeller (13) having a projected portion (19) at a center of a rear surface; a drive shaft (15) connected to a bottomed coupling hole (20) provided in the projected portion (19) of the compressor impeller (13) through interference fit only; and a sleeve (30) with a cylindrical portion (33) connected to the outer peripheral portion of the projected portion (19) of the compressor impeller (13) by fitting only. The sleeve (30) is formed of a material whose coefficient of linear expansion is smaller than that of the compressor impeller (13). Accordingly, even when the coupling hole (20) in the projected portion (19) undergoes thermal expansion and the diameter of the coupling hole (20) increases, a connection between the drive shaft (15) and the coupling hole (20) can be prevented from being loosened since the radial increase thereof is suppressed by the cylindrical portion (33). Thus, the state of the connection thereof can be well maintained.

摘要： One of the swing shafts 32 of the nozzle vanes 31 is selected so as to operate as swing drive shaft 33 that projects to the outside. As the swing drive shaft 33 is driven to revolve, all the nozzle vanes 31 are driven to turn by a same angle by way of the driving lever 21 and the coupling ring 18 linked to it. Therefore, it is only the swing drive shaft 33 that projects to the outside, the projecting part can be sealed in a simple and reliable manner to improve the sealing effect and the durability of the variable geometry turbocharger. Additionally, since the rotary motion of the swing drive shaft 33 is directly used to driven the nozzle vanes 31 to swing, the mechanism for transmitting the driving force is simplified.

摘要： There is provided a turbocharger whose constitution is compact, in which exhaust interference seldom occurs, and which can be applied also to an EGR type engine. In the turbocharger, an introduction part of an exhaust inflow passage possesses a partition part dividing a range from an inlet to a predetermined position in a downstream of the inlet into two exhaust inflow passages, a throttle part, whose sectional area becomes gradually small, from the inlet to a position where the partition part ceases, a joining part where exhaust gases passing through the left and right exhaust inflow passages are joined, and a diffuser part, whose sectional area becomes gradually large, from the joining part to a tongue part.
