摘要： A gas passage that is connected to an exhaust passage and a water passage that is connected to a water jacket are formed in a turbine housing. The water passage and the gas passage are arranged adjacent to each other in an exhaust gas-introducing side joint part of the turbine housing, and a mating face in which the water passage opens and a mating face in which the gas passage opens are formed not to connect smoothly to each other. The turbine housing is attached to the cylinder head with an O-ring that prevents leakage of coolant interposed between the mating face and the cylinder head, and a seal member that prevents leakage of exhaust gas interposed between the mating face and the cylinder head.

摘要： A compressor housing includes a housing body for enclosing an impeller, an inlet portion for introducing air toward the impeller, and a port portion arranged adjacent to the inlet portion. A valve body for opening and closing a bypass passage, which bypasses the impeller, can be rested against the port portion. A connection hole, to which a return passage for returning blow-by gas of an internal combustion engine is connected, is formed in a side wall of the inlet portion. The inlet portion and the port portion have a common wall. A communication hole, which configures a part of the return passage, is formed in the common wall. The communication hole is formed such that the projection plane defined by projecting the communication hole onto a surface of the side wall having the connection hole along the axis of the communication hole is contained in the connection hole.

摘要： A turbocharger includes a drive shaft to transmit a driving force of an actuator to a mechanism in the turbo housing, and a bush to rotatably support the drive shaft, wherein a seal is provided at an end portion on the open-air side of the bush. The seal includes a seal body made of resin and a metallic spring fitted into a recessed portion of the seal body, wherein an internal lip portion of the seal body is pressed by the elastic force of the spring to the outer circumferential surface of the drive shaft. Further, an end surface that is contactable with a member (drive link) disposed on the open-air side of the drive shaft is formed in the seal body. The seal having the above-described structure is provided at the end portion on the open-air side of the bush so as to achieve excellent sealability, so that this securely prevents exhaust gas in the turbo housing from passing through between the outer circumferential surface of the drive shaft and the inner circumferential surface of the bush and flowing out to the outside.
