An oil level regulator is provided for controlling the oil level in the crankcase of one or more refrigeration compressors or the like. The regulator has a closed chamber for containing the oil. An inlet valve assembly extends into the chamber and includes a float-controlled valve for introducing liquid into the chamber as necessary to maintain the oil level in the chamber and compressor crankcases. The inlet valve assembly includes a vertically telescoping piston for adjusting the float valve and the oil level regulator in the regulator chamber. The piston is moveable from outside the chamber in response to rotation of a concentric stem having a bore through which oil flows into the chamber. The float valve includes a lever bracket which extends horizontally across the chamber to contact a top of a float ball. The lever bracket pivots to cause side-to-side motion of a valve needle against a valve seat to control oil flow into the chamber.
