Abstract

240,773. Shaw, H. S. Hele-, and Beacham, T. E. March 28, 1924. Lubricant conveyed by fluid; force-feed lubricating.-In an air compressor of the type de. scribed in Specification 237,323, the air entering the machine is impregnated with lubricant, the latter, after compression, being separated from the air and returned for use in the compressor. As shown, a shaft 24, Fig. 1, carrying revolving cylinders, has an opening 56 formed with a throat and serving as the air inlet to the compressor. The reduction of pressure occurring at the throat sucks up, through passages 97, 98 lubricant that collects in a sump 96 at the bottom of the compressor casing, such lubricant being conveyed by the air through the machine to a separator 70. A lubricant sprayer may be fitted in the air inlet. The separated lubricant is then forced through a pipe 85 to an axial passage 86, Fig. 3, in the stationary cylindrical valve 26, from whence it passes through radial passages 87 to circumferential grooves 88<b>, 88<c> on the valve surface. A groove is arranged between the low and high pressure port openings 52, 60, the grooves 88<b>, 88<c> being between such port openings and the ends of the valve. Lubricant escaping from the rubbing surfaces of the machinery drains into the sump 96 and passes up the passage 97 to be again used in the compressor.
