ABSTRACT:
A service valve (10) is provided to provide an apparatus and method for filling a constant speed drive without overfilling and for preventing gas entrapment in the oil circuit of the drive. The valve (10) has a spool (12) movable in response to pressure from a filling fluid so as to connect the filling fluid with the drive circuit until a predetermined level has been reached at which point a signal is generated to allow the operator to remove the source of filling fluid. An air vent float valve (44) and a pressure switch (28) in the oil circuit allow the trapped gas to be vented from the oil circuit.
