I'm considering the method of returning oil to the compressor from the separator and I'm at odds as to how I can do it. The obvious decision seems to be to discharge it through the suction line close to the compressor. I am considering another conclusion, but I'm not certain of its feasibility.
I am going to be modifying the compressor to add an oil drain. The drain will have direct access to the oil chamber. As you might guess I am thinking of piping the oil separator oil outlet directly to that port for direct oil return. However, I am not certain of its feasibility. The solenoid controlling the drain line would be on a 5 second circuit (given active power through the compressor).
What do you think?
