摘要:
A higher reliable air control valve capable of improving producibility and reducing manufacturing cost without unpleasant characteristic change under operation. An air control valve includes: a bobbin wound by an energizing coil; a fixed plate for covering one end of this bobbin to construct a magnetic path; a yoke for at least partially covering the other end of said bobbin and an outer peripheral portion of the energizing coil, and being engaged with said fixed plate to constitute the magnetic path; an exterior member for constituting an exterior of said energizing coil and for making up the bobbin, the fixed plate, and the yoke in an integral form; a fixed core fitted into an inner diameter portion of said bobbin and fixed to said fixed plate; a movable core slidably inserted into the inner diameter portion of the bobbin along an axial direction and on which a valve body is slidably mounted via a spring at one end thereof along the axial direction; a return spring mounted between a spring adjusting member provided with said fixed core and said movable core; and a housing having an air inlet port, an air outlet port, and a valve seat provided in an air passage between said air inlet port and said air outlet port. Both said valve body mounted on said movable core and said valve seats of the housing constitute a valve; and said inner diameter portion of said bobbin is a guide for slidably holding said movable core along the axial direction.
