FIELD: machine building.SUBSTANCE: sealing metal springy ring is of U-shaped profile in its cross section, the junction sealing is performed on the noninclined solid wall of the profile. The noninclined solid wall of the profile is fitted by flat cut-outs or slots with folded surfaces, the sizes of the cut-outs and inclination angle of the folded surfaces are defined by the specified working medium flow rate. The proposed technical solution can be used as a sealing device, at joining air ducts with different devices or to each other, at joining of gas turbine engines of airborne vehicles with air intake devices.EFFECT: leakproofness of flanged edge joints with working medium bypass of specified flow rate.2 cl, 7 dwg |
