ABSTRACT:
A refrigerant recovery system that includes a compressor having an inlet and an outlet, and an oil separator connected to the compressor inlet for separating oil from refrigerant recovered from equipment under service. A check valve is connected between a vapor outlet port on the oil separator and the inlet of the compressor for feeding refrigerant directly to the compressor inlet. A pressure sensor is connected to the oil separator for indicating refrigerant vapor pressure within the separator, and a valve is automatically responsive to such refrigerant vapor pressure for connecting a vacuum pump between the oil separator vapor port and the compressor inlet in parallel with the check valve when refrigerant vapor pressure at the oil separator falls below a predetermined value.
