Abstract: A compressor system includes an inlet for receiving a fluid stream, a compressor in communication with the inlet, a separator in communication with the compressor, and a vent. The compressor system also includes a flow diversion control device in communication with the inlet, the compressor, the separator, and the vent, where the flow diversion control device has a first port in fluid communication with the separator, a second port in fluid communication with the inlet, a third port communicatively coupled with the inlet, a fourth port in fluid communication with the vent, and a mechanical valve having a first orientation configured to connect the first port to the second port and the third port to the fourth port for unloading the compressor system, and a second orientation configured to connect the first port to the third port and the second port to the fourth port for loading the compressor system.

Abstract: A compressor system includes: a compressor having a suction side and a discharge side, wherein the compressor is operative to compress a gas using oil, wherein the suction side operates at a suction pressure and is operative to receive a the gas and the oil into the compressor; and wherein the discharge side is operative to discharge the compressed gas and the oil; a gas/oil separator tank operative to store oil separated from the compressed gas for subsequent use by the compressor; a supplemental oil reservoir in fluid communication with the suction side; and a valve operative to, when opened, expose the supplemental oil reservoir to the suction pressure of the suction side of the compressor, and draw oil from the supplemental oil reservoir by suction into the suction side of the compressor.
