ABSTRACT:
The invention comprises an arrangement, for use particularly in connection with a rotary displacement machine such as an air compressor, in which the fluid (air) compressed in the machine is employed to supply lubricant cyclically to the mating or coacting surfaces of the confined rotary piston and the walls of the compression chamber. A lubricator valve, having a translating piston and integral stem, is employed to extract oil from a repository supplied by an oil pump, and introduce it into a tapped-off compressed air line for pressurized injection into the compressor.
