Vent valve for a compressor, especially for a dual flux jet engine

摘要

The bleed valve has a dissipation screen(5d) provided in the bleed passage(5a) between the valve body(5b) and deflector(5f). A stabilizing chamber(5e) is provided in the direction of the bleed air flow(6) when viewed downstream of the dissipation screen. The deflector is in the form of a plate parallel to the wall of the bypass passage(3) and in which there is a number of holes inclined in the flow direction of the air flow directed through the bypass passage.
