Description

The invention relates to compressors, for example compressors for gas turbine jet engines

The invention creates a compressor, which in a compressor » GehSpse is housed, one of half of this standard housing arranged chamber, which is connected to the compressor via a single opening or a single series of openings in the Compressor housing communicates and a first and a second valve device connected to this chamber, de is set up to allow air to flow from the compressor and through the chamber «

This chamber is preferably ring-shaped on the compressor housing and communicates with the compressor through an annular row of openings in the compressor housing

The first valve device comprises an annular valve locking member, * which cooperates with an annular seat in the wall of the annular chamber.

The second valve device comprises one communicating with the chamber Line, the flow through this line being controlled by a flap valve inside it.

As a precaution, this single opening or single row of openings is permanently open, so that the chamber is uninterrupted of the compressor communicates

The compressor can be the high pressure compressor of a bypass gas turbinens trieb «erks, which has a low-pressure compressor, a high pressure compressor, an incinerator, a high pressure turbine and a low pressure turbine, as well as one Includes shunt, duvch the part of the dated Low pressure compressor can dream of air coming through to bypass the incinerator and the turbines Chamber can therefore be provided in this bypass line

The invention also includes a gas turbine jet engine equipped with such a compressor.

In addition, the invention also includes one with such Engine equipped aircraft · This aircraft may be equipped with blue flaps that supply compressed air from the compressor can be supplied via the second valve device.

Further advantages and characteristics of the invention emerge from
