Suction of used oil from engine crankcases and automatic transfer to storage

摘要

The oil extraction unit has a suction generator (E) creating high vacuum in a transfer chamber (CV) connected through a hose (1) to the crankcase (CH) of the engine. An end-of-travel switch on the hose winder limits unwinding and rewinding of the hose. The hose movement and suction are controlled automatically. A level control monitors the level of the oil collected in the chamber.
