流板fを設けたものも提案されている。In a general turbocharger, the inlet part of the compressor is simply connected by a connecting hose, and some parts other than the connecting hose are described in, for example, JP-A-58-185933. As shown in FIG. 3, an inlet guide vane c is provided in the intake pipe b at the inlet of the blower a, or upstream of the compressor d as described in JP-A-58-210324 and shown in FIG. There is also proposed a device in which a current plate f is provided in the intake pipe e.

を増大させる点において改善の余地が残されていた。By providing these inlet guide vanes and straightening vanes, it can be expected to exert some effect, but in any case, it is necessary to install the inlet guide vanes or straightening vanes inside the intake pipe. There was room for improvement in terms of increasing the work process.

ヤージヤの吸気装置を提案するものである。Here, the present invention proposes an intake device for a turbocharger in which a pre-turning vane is integrally formed on the inner peripheral surface of a connecting hose connecting an intake pipe to the compressor inlet of the turbocharger.

れるものである。That is, in the device of the present invention having the above-mentioned configuration, the pre-turning vane is previously formed by integral molding on the inner peripheral surface of the connecting hose connected to the compressor inlet of the turbocharger, and the connecting hose is connected to the compressor inlet. By simply connecting to, it is possible to obtain the same action and effect as the guide vanes and straightening vanes conventionally installed separately in the intake pipe.
次にこの考案の実施例を第1図及び第2図にしたがつて
詳細に説明する。Next, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.

ものである。In the figure, 1 is turbocharger, 2 is Durbin,
3 shows a compressor, respectively. In this invention, for pre-turning to give pre-turning to the inflow air in order to improve the performance of the turbocharger on the inner peripheral surface of the connection hose 6 such as a rubber hose for connecting the suction pipe 5 to the inlet 4 of the compressor 3 The vane 7 is formed by integral molding.

ヤージヤの特性上不足する。The air sucked into the chibo-charger 1 enters the co-pressor 3 from the suction pipe 5 through the connecting hose 6, and the air is compressed and discharged by the compressor 3. For example, air in the low speed rotation range of the engine is insufficient due to the characteristics of the turbocharger.

エンジンの性能、機能の改善が図れるものである。In view of this, in this invention, a pre-swirl vane 7 for giving an optimum pre-swirl to the inflow air of the compressor 3 is formed on the inner peripheral surface of the connection hose 6 by integral molding. It improves intake efficiency, increases the amount of air in the low speed range, improves engine performance, and reduces exhaust gas levels. Furthermore, in general, an engine with a turbocharger has excess air at high speed, which reduces engine efficiency, but by installing the device of the present invention, the amount of air in the high speed range can be optimally reduced.
The performance and function of the engine can be improved.

点において極めて有用なものである。According to the above-mentioned structure of the present invention, the intake pipe and the inlet of the compressor are connected by the connecting pipe without the need to separately install guide vanes, straightening vanes, and the like to the intake passage of the intake system of the durvochair. Since it is possible to give the optimum pre-swirl to the intake air only by itself, it is extremely useful in that it can be carried out at low cost and easily as compared with various structures proposed hitherto.
