<P>PROBLEM TO BE SOLVED: To control the quantity of bypass air flowing through the respective bypass air outflow holes uniform with high accuracy in a control device for controlling the openings of a plurality of air outflow holes using a single bypass valve. <P>SOLUTION: A bypass air inflow hole 3 is opened in the bottom 2a of a sliding valve guide cylinder 2, first bypass air outflow holes 5 and second bypass air outflow holes 6 are opened with a hole pitch P in the side wall, and further a slit groove 4 is recessed from one end 2c to the bottom 2a. The bypass valve 11 is formed by integrally connecting the first valve part 11a and the second valve 11b by a small-diameter connecting part 11c. A first bypass air chamber 12 is formed by the bottom 2a of the sliding valve guide cylinder 2 and the end face 11a2 of the first valve part 11a, the first bypass air of the first bypass air chamber 12 is controlled by the openings of the first bypass air outflow holes 5 controlled by the first valve part 11a, and the second bypass air in the second bypass air chamber 13 formed by the opposite end faces 11a1, 11b1 of the first valve part 11a and the second valve part 11b is controlled by the opening of the second bypass air outflow hole 6 controlled by the second valve part 11b. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
