ABSTRACT:
The impeller bearings in a turbocharger on an internal combustion engine are supplied with a coolant, in the form of lubricating oil from the engine's crankcase, during post-shutdown coasting of the impeller. This coolant is supplied by an accumulator including a piston having an upstream side which is subjected to oil under pressure from the crankcase during engine operation to move the piston downstream for loading a spring affixed to the downstream side of the piston. Coolant leaking downstream of the piston is returned to the crankcase through a valve seat which is closed during engine operation by a valve extending from the downstream side of the piston.
