Abstract RU 2518719 C2

FIELD: engines and pumps.

SUBSTANCE: air starter comprises front case (12), rear case (14), exhaust gas flow circular channel (32) and cylindrical grate (44) of said channel (32). The latter is open between front case rear end and rear case front end. Discharge grate front and rear ends comprises means (48, 52) of retention of front case (12) and rear case (14) in axial direction towards grate (44). Said retention means (52) allows relative rotation of grate (44) and said case (14). Rotation forces can be dissipated to allow rotation of front case relative to rear case.

EFFECT: decreased weight, higher reliability, integrity of starter at turbine blast.
