ABSTRACT:
An apparatus and system for immediately lubricating a compressor within a compressor system using a suction oil line apparatus. The compressor system comprises a compressor, a power source for operating the compressor, a tank capable of storing oil therein, a conventional oil line, and a suction oil line apparatus. The suction oil line apparatus can comprise a suction oil line and a valve. When the power source is actuated, gas is introduced into a suction cavity within the compressor, drawn into a compression chamber within the compressor, and compressed. The compressed gas is discharged into a tank thereby elevating a tank pressure. The elevated tank pressure causes the oil within the tank to be transported through the suction oil line. Transportation of the oil through the suction oil line permits immediate lubrication of the compressor to occur following start-up of the compressor, immediate being from about one second to about one minute. Start-up can comprise initiation of the compressor, movement of components within the compressor, movement of intimate components within the compressor, or actuation of the power source. When the tank pressure reaches a pre-determined pressure, the valve in the suction oil line is closed. The closed valve results in the oil being prohibited from flowing through the suction oil line and permitted to flow through the conventional oil line. As such, the compressor remains continuously lubricated. Further, immediate lubrication can be accomplished without the need for a back-pressure valve or pump.
