Intake joint structure for turbocharger

Disclosed is an intake joint structure capable of blocking backflow of lubricating oil 18 at a connection position between an air inlet 12 of a turbocharger and a suction pipe 24. A backflow-preventive plate 25 is integrally molded to have a cylindrical portion 25a fitted over the air inlet 12 and a...

Beschreibung
Zusammenfassung:	Disclosed is an intake joint structure capable of blocking backflow of lubricating oil 18 at a connection position between an air inlet 12 of a turbocharger and a suction pipe 24. A backflow-preventive plate 25 is integrally molded to have a cylindrical portion 25a fitted over the air inlet 12 and a tapered portion 25b curved inward from an upstream end of the cylindrical portion 25a and converged downstream to provide an open end. A downstream end 24a of a suction pipe 24 is molded by soft material over a predetermined range using exchange blow molding. The cylindrical portion 25a of the backflow-preventive plate 25 is fitted over the air inlet 12 through a grommet 26 (first soft layer) and the downstream end 24a of the suction pipe 24 is fitted over the cylindrical portion 25a and is banded by a hose band 27.
