ABSTRACT OF THE DISCLOSURE An improved bleed valve for the compressor of a gas turbine engine comprises a port communicating with the intermediate section of the compressor. An annular valve seat surrounds the port, the valve seat having a radial sur- face terminating in an outer peripheral circular rim. A piston is provided having a flat radial surface and adapted to close on the valve seat, the piston having a peripheral inner cylindrical surface having a diameter corresponding to the outer circular rim of the valve seat. The axial component of the piston inner peripheral surface is chosen such as to be sufficient to close the so-formed nozzle just prior to the piston radial surface closing on the valve seat to prevent chattering of the piston caused by diffuser effect.
