項記載のウエストゲート制御装置。[Claims for Utility Model Registration] 1. A pressure capsule connected to a valve body of a waste gate so as to control the valve body, the first pressure capsule being loaded by the compressor outlet pressure of the supercharger. Can be connected to a negative pressure source via a pressure chamber and a solenoid valve. The exhaust turbo is a pneumatic engine for internal combustion engines equipped with a supercharger, in which the rising pressure in the first pressure chamber counteracts the force exerted on the valve body by the closing spring. In a type wastegate control device, - the first pressure chamber 18 is loaded by the compressor outlet pressure in the entire load range of the engine 1, and a negative pressure source is provided for serving additional devices;
The second pressure chamber 19 and the negative pressure generator 22 are operated by the second pressure chamber 19 and the negative pressure generator 22 in the low load range of the engine 1 where the output is not increased by the supercharger.
the solenoid valve 23 in the direction of starting to open the connecting pipe 21 between the
is controlled by a switch 24 which is operated depending on the load, such that the wastegate 9 is opened by vacuum in the low load range and by compressor outlet pressure in the high load range.
The surface of the valve body 13 exposed to exhaust pressure, the pressure capsule 16
and a closing spring 17 are formed. 2. Utility model registration claim 1 characterized in that in the engine 1 equipped with the fuel injection pump 11, the switch 24 is connected to the adjustment lever 12 of the injection pump 11.
The wastegate control device described in Section 1.
