が不可能となってしまう。Known adjusting devices of the above type (Porsche Technic Information III 6.8.1-2゜1
In 976'2.16) the first pressure chamber is connected to an external control conduit with many curves. A disadvantage with this known construction is that the control 1 conduit is expensive to manufacture. In addition, the control conduit can be damaged by vibrations or thermal effects, making it impossible to adjust the boost pressure to function and to protect the internal combustion engine from load overloads.

従って本発明の課題は、前述の各欠点を回避し得る手段

端な落下も防がれ得る。The main advantages provided by the present invention are that the holes provided in the valve eliminate the need for said external control conduits;
This not only saves expensive components, but also ensures safe and reliable operation of the adjustment device in question. Furthermore, by connecting the pressure chambers to the respective pressures before and after the compressor/turbine unit, the best boost pressure characteristic curve is obtained. That is, the supercharging pressure is relatively high even at low rotational speeds, and an extreme drop in intake pressure at high rotational speeds can be prevented.
