FIELD: engines and pumps.
SUBSTANCE: invention relates to development of gas turbine engine, particularly, to turbo-shaft engine discharge device gas collector. Gas collector inner case houses oil feed pipe furnished with tip with resilient damping-sealing rings while angle piece has the groove made for assembly purposes corresponding to tip length. Oil feed pipe one end is welded to angle piece (case) while said tip is welded to the opposite end, damping-sealing rings being fitted in tip grooves.
EFFECT: decreased strains in pipe caused by variable temperature and dynamic stress.
