<P>PROBLEM TO BE SOLVED: To provide a turbocharger in which a variable volume valve and a waste-gate valve are driven by an electric actuator; deformation of a cam plate caused by heat is prevented; and backlash in an engaged portion of a cam groove is also prevented. <P>SOLUTION: A variable volume valve 2 and a waste-gate valve 3 are driven by an electric actuator 4 and a link device 30. The link device 30 includes: a cam plate 5 driven by the electric actuator 4; a first link 31 transmitting displacement of a cam groove 33 of the cam plate 5 to the variable volume valve 2; and a second link 32 transmitting displacement of a cam groove 33 of the cam plate 5 to the waste-gate valve 3. The electric actuator 4 and the cam plate 5 are mounted on a compressor housing or the like other than a turbine housing 6, to thereby place the electric actuator 4 and the cam plate 5 in a low-temperature environment. <P>COPYRIGHT: (C)2012,JPO&INPIT |
