FIELD: mechanical engineering. SUBSTANCE: invention relates to support seals for rotating shafts, reciprocating piston rods, etc. taking of load and increasing serviceability of device is provided by organization of delivery of high-pressure working medium between moving surfaces. Sealing bushing is L-shaped one web of which is fitted in radial groove of housing, and through other web housing rests on cylinder. Drain chute is made on bushing from side of high-pressure space. Said drain chute communicates with low-pressure space through drain channels. EFFECT: improved reliability of seal. 44 cl, 32 |
