End gasket has body, bushing, shaft, rotary and non-rotary friction rings, those are in contact one with another at flat friction surface, on the flat friction surface of rotary ring circular groove is provided, this is connected with long channels to placed in radial positions cavities, those are connected to sealed cavity through inserts with L-shaped channels screwed to the bushing. Inserts with L-shaped channels are arranged as injectors with tangent and radial with respect to the bushing channels, in the tangent channels inserts are placed and fixed, to change in length dimensions of cross sections of tangent channels, cross sections with largest dimensions are placed at the beginning and at the end of tangent channels. Sections of tangent channels with smallest dimensions are placed over radial channels. Injectors are installed in tangent positions with respect to bushing in plane normal to axis of rotation of the shaft in such way that at rotation of the bushing liquid moves at tangent channels with varying cross sections. |
