ABSTRACT:
The compressor includes a housing defining a pressure space including chambers and passages connected thereto for conveying sealing and lubrication liquid to and from an impeller shaft rotatably mounted in the housing. The impeller shaft is stepped and mounted for limited radial movement, and includes an elastically bendable torsion shaft portion having a diameter which is a minimum with respect to the torsional stresses imposed thereon. A relieving piston is carried by the torsion shaft portion and the impeller shaft further includes a main compressor shaft portion carrying at least one impeller. A torsion shaft sealing surrounds the torsion shaft portion and serves as the main sealing forming a shield between the pressure within the pressure space and atmospheric pressure. A sleeve surrounds the relieving piston and is formed with axially spaced grooves in its surface facing the relieving piston, and annular discs are mounted on the relieving piston and cooperate with the grooves to compensate the axial thrust. A chamber is defined, on the one hand, by the torsion shaft portion and the torsion shaft sealing end, on the other hand, by the relieving piston, the sleeve and the housing, and a supply conduit is connected to this chamber to supply sealing and lubricating liquid thereto serving to absorb the internal pressure within the housing.
