<P>PROBLEM TO BE SOLVED: To provide a turbo-charger in which the oil and/or dust in the air drawn out of a compressor outlet part is not supplied to constituent parts located downstream. <P>SOLUTION: The turbo-charger is equipped with a turbine wheel in a turbine housing and a compressor wheel 7 in a compressor housing 6. The turbine wheel and the compressor wheel are rotated through a common shaft. The turbine housing is equipped with a waste gate valve assembly, while the compressor housing is furnished with a command valve 22. A pneumatic type waste gate actuator is installed between the waste gate valve assembly and the command valve 22. The actuator is tied to a suction outlet vortex chamber of the compressor through a boost blowing pipe and the second boost air outlet passage 25 of the compressor housing. The forefront opening 25a of the second boost air outlet passage 25 is formed apart from the wall surface of the vortex chamber 15 as the compressor outlet part. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
