Abstract:
An electromagnetic valve comprising:a seat member having a fluid passage including a radial fluid passage part through which fluid flows, a valve seat, and means for positioning and preventing rotation; a valve capable of closing the fluid passage when the valve comes in contact with the valve seat; a resin base member surrounding the seat member by insert molding and having an opening provided at a given circumferential position to communicate with the radial fluid passage part; a driving member fixed to an axial end of the base member for generating a magnetic attracting force, when energized; and a moving member for moving the valve in a predetermined direction upon receiving the magnetic attracting force, wherein the means for positioning and preventing rotation serves to position the seat member so that the fluid passage extends radially to an angular position corresponding to the opening of the base member, and wherein the means for positioning and preventing rotation is partly surrounded by the base member so that the seat member is prevented from rotating in the base member after the inserting molding.
