Title: Improvements in or relating to rotary compressors or the like
IPC: F16J15/40
Filed: 1923-12-27
Abstract: 223,777. Jackson, W. J. Mellersh-, (Carrier Engineering Corporation). Dec. 27, 1923. Balancing moving parts ; leakagepreventing devices.- The shaft opening of a compressor casing is sealed while the compressor is running by a sealing liquid under pressure and is closed when the compressor stops bv a member 10. The sealing liquid acts to separate the member 10 from an opposing member in opposition to the end thrust of the compressor, but this action stops when the compressor stops. One end of the shaft C is completely enclosed in the compressor casing while the other end rests in the bearing D, Fig. 4, and passes through the casing for connection to the driving turbine. The thrust balancing and sealing collar 10 is secured to the shaft between the shoulder 11 and the coupling member 12, and it faces a stationary annular part 13 of the casing which forms the inner end of the annular sealing chamber 14. The stop member 13 may be a bushing secured in a seat 15 by a cylinder 16 secured in turn by a circular rib on an end piece 18 bolted on the casing. The sealing chamber 14 is formed by an annular recess in the inner end of the cylinder 16. A flange 21 on the part 16 forms a cylinder in which slides a piston 23 with a tubular hub 24 sliding inside the flange 22. A spring 26 tends to hold the hub 24 against the sealing member 10. The parts 15, 16 contain ports and ducts to lead the sealing liquid to the chamber 14 and the proper surfaces. The liquid is preferably lubricating oil and is delivered to the reservoir 30 by a pump associated with the compressor; from the reservoir it passes by the passages 31, 32, 32<a> to the sealing chamber 14, and also from the top of the reservoir it passes through the passages 34, 35, 35<a> to the chamber. Liquid also passes through the passages 37 to operate the piston 23. The member 10 rotating in the liquid forms a centrifugal liquid seal while the compressor and pump are running. When the compressor stops the pump also stops its delivery to the reservoir 30, and the oil drops below the level of the end of the pipe 34 and can only discharge through pipe 31. The pressure on the piston is thus relieved and the spring 26 operates to restore the parts to their initial positions with the sealing member 10 in contact with the stop member 13 while an oil film is maintained between the parts. While the machine is working, leakage oil is thrown outwards from the ridges 44 on the shaft to the semicircular plates 45 from which it drips into the end piece 18 and passes to the chamber 47. Specification 218,201 is referred to.
