Oil suction device for exhaust gas turbocompressor

摘要

The oil suction device is used in an IC engine with gas exchange channels in the cylinder head, to which an exhaust turbocompressor is connected. The compressor is linked to the lubricating oil circuit. The oil suction device is fitted in the oil return line (8) from the compressor (5) to the IC engine. This device may be in the form of an oil pump (7). The oil pump may be electrically driven. As an alternative, an ejector pump may be used, in which case it is fitted on the induction side of the engine oil pump (3) and connected to a pressure lead from this pump. There may be a non-return valve (9) in the oil return line.
