ABSTRACT:
A rotary compressor features a passage structure and valve arrangement which, under given modes of operation, permits relatively hot gaseous compressed working fluid to be introduced into a chamber proximate a bearing which is subject to cooling and the lubricant therein subject to dilution by working fluid under such conditions, in a manner to warm the bearing and its immediate surroundings and obviate the dilution problem.
