FIELD: machine building.SUBSTANCE: metal seal is made out of spring metal plates and has shape of thin-wall cylindrical shell, its one part is made continuous, and on the other part the radial cutouts are made along perimeter. Besides, the cylindrical sealing device with working medium by-pass is described, it is characterised by that contains first hollow cylinder with internal recess, second hollow cylinder and metal seal, secured by continuous part on the internal recess on the first cylinder and resting by part with cutouts against the internal surface of the second hollow cylinder, at that part of cutouts along length is located between the sealed first and second hollow cylinders.EFFECT: invention simplifies the design, and reduces resistance to air flow during operation.3 cl, 5 dwg |
