FIELD: machine building.
SUBSTANCE: discharge valve contains flapper (116, 216), sealing gasket (152, 252) and attachment devices (158, 258) for this sealing gasket on peripheral edge of flapper. Flapper (116, 216) is meant for installation with possibility of its turning against axis (120) between position of overlapping of orifice (14) meant for air passing and position of this orifice opening. Sealing gasket (152, 252) passes along at least a part of peripheral edge of flapper. Flapper and attachment devices of sealing gasket are made from plastic material and are formed as a single part or rigidly attached to each other by welding or bonding. There is also gas turbine engine which contains at least one abovementioned discharge valve.
EFFECT: simplifying valve design and consequently gas turbine engine as a whole.
