<p>A suction control valve providing little leakage of suction air, capable of controlling the volume of suction air highly accurately, and easily mountable to a suction manifold. The suction control valve of the suction control device according to the invention has a valve body (30), a case (20) and an actuator (40). The valve body (30) is rotatably accommodated in the case (20) so as to open and/or close an open/close passage (23) formed in the case (20). The actuator (40) is mounted to the case (20) so as to drive the valve body (30). A mounting hole (51) in which the case (20) is inserted is formed in a suction manifold (50). Sealing materials (27), (28) are provided on the outer side of the case (20), which are brought into contact with the wall surface of the mounting hole (51) so as to prevent the leakage of air. After the valve body (30), the case (20) and the actuator (40) have been assembled into the body, the suction control valve is fitted in the mouting hole (51) formed in the suction manifold (50). <IMAGE></p> |
