Turbo-charged heat engine arrangement for motor vehicle, has pressure balancing duct connecting chamber with oil circulating element to avoid closing of duct by plug and to balance pressure for avoiding overpressure of oil in bearing

摘要

#CMT# #/CMT# The arrangement (10) has a turbo-charged heat engine (12) comprising a sump (14) filled with oil (16). An oil supply duct (34) connects an oil pump (36) with a central bearing of a turbo-charger (18), and an oil evacuation duct (42) connects the bearing with the sump. An additional pressure balancing duct (48) connects a chamber with an oil circulating element (50) e.g. blow-by duct, to avoid closing of the duct (48) by an oil plug and to balance pressure for avoiding overpressure of oil in the bearing. The element is arranged above a determined level (h) of the oil. #CMT#USE : #/CMT# Arrangement for a turbo-charged heat engine of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The arrangement optimizes the lubrication of the turbo-charger in a simple and effective manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a turbo-charged heat engine arrangement. h : Determined level 10 : Turbo-charged heat engine arrangement 12 : Turbo-charged heat engine 14 : Sump 16 : Oil 18 : Turbo-charger 34 : Oil supply duct 36 : Oil pump 42 : Oil evacuation duct 48 : Additional pressure balancing duct 50 : Oil circulating element.
