Abstract
PURPOSE: To reduce fluctuating width of load torque in such a way that the load torque is made remarkably less at the time of opening a valve box 9 corresponding to the peak torque by providing a seal plate 7 on the upstream side of a gas passage in a valve 9 for sealing between the valve box 9.
CONSTITUTION: In full open and closed conditions of the opening degree, seal plates 4, 7 are open to a certain extent, static pressure between a vehicle compartment 1 and a valve box 9 is equalized. When with the valve throttled, the valve opening degree comes near to the valve opening degree corresponding to peak torque, because static pressure in a point b is lowered and relationally static pressure in a point (a) is made higher, the seal plate 7 makes it narrower so that pressure influence at the point (a) may not strongly work on the surface B. In consequence, since with the peak torque reduced, the pressure worked on the surface B is rather reduced, the lowered static pressure worked on the surface B than the static pressure on the surface (A) will make the torque work in the direction of opening the valve.
