Emergency use lubricating device for exhaust gas drive-type supercharger, has inlet pipe to compressor bearing connected to connecting pipe which has percolation opening cross-section always opened toward storage tank

摘要

A loop (2) is connected to at least one lubricating-oil supply pipe (1). An inlet pipe (4) to a turbine bearing and an inlet pipe (5) to a compressor bearing come out from under the loop. The inlet pipe to the compressor bearing is connected to a connecting pipe (6) which has a percolation opening cross-section always opened toward a storage tank (7). A non-return valve (8) is opened from the storage tank to a back-flow direction at the time of failure of pressure inside of the loop.
