FIELD: mechanical engineering; compressors.
SUBSTANCE: compressor sealing unit contains partition isolating bearing space from space of drive transmission, with two labyrinth bushings between which gauge pressure air is delivered and deflector installed on shaft. According to invention, fixed diaphragm is attached to partition, and deflector is installed relative to diaphragm forming ring clearance communicating with atmosphere through bearing space.
EFFECT: improved reliability of compressor in operation owing to improvement of sealing unit of bearing supports.
