<p>An oil control system and regulator for controlling the oil level in the crankcase of one or more refrigeration compressors or the like are disclosed. The regulator comprises a shell and end cap closures defining a closed chamber for containing the oil. An inlet extends through one of the end cap closures and includes a float controlled valve for admitting liquid to the chamber as necessary to maintain the oil level in the chamber and compressor crankcases and also includes a piston which is movable up and down to adjust the float and the oil level in the regulator chamber. A threaded adjusting pin extends through the end cap closure and into the chamber and threads on the adjusting pin are threaded through a coupling bracket which couples the pin with the piston to move the piston, float and valve for adjusting the oil level.</p> |
