Title:

LUBRICATING DEVICE FOR DOUBLE ACTING PISTON TYPE COMPRESSOR FOR ENGINE SUPERCHARGING

Document Type and Number:

Japanese Patent JP2000038925

Kind Code:

A

Abstract:

To surely lubricate a double acting piston type compressor for supercharging without causing an influence on the operation of an oil pump for an engine by using engine lubricating oil.

A lubricating oil path 89 for a compressor is branched from a lubricating oil path 87 for an engine in an oil pump P1-bearing engine E. The downstream end is opened to a ring groove communicating with an operating chamber on the inner peripheral surface of a pump cylinder body in a double acting piston type compressor for supercharging. Part of the lubricating oil flowing on the lubricating oil path 87 for the engine is supplied to the lubricating oil path 89 for the compressor at the pump cylinder body side. A second pump P2 having capacity smaller than that of the oil pump P1 is provided.
