ABSTRACT:
The invention comprises a subsystem or assembly which lends itself to retro-fitting to a machine to controllingly supply oil to the machine. In the embodiment shown by way of example, the invention supplies injection oil and lubricating oil to an oil-injected and oil-lubricated gas compressor, and includes a pressure-responsive metering device for regulating the relative quantities of injection and lubricating oil supplied pursuant to the operating condition of the compressor. Particularly the invention comprises the use of a small, inexpensive oil pump, to supply substantially only lubrication for the compressor on start-up, and by-passes the pump, when substantially "on line" (i.e., with the compressor discharge pressure elevated), and then supplies less of the oil for lubrication purposes and more for injection (for compressor sealing and cooling).
