An electromagnetic valve has an electromagnetic coil, a main body arranged adjacent to the coil, a fixed core arranged inside of the coil, and a movable core arranged inside of the coil and beside the fixed core such that a space exists between the movable and fixed cores. A cylindrical sleeve is arranged on a side surface of the main body and a cylindrical spool valve is arranged in an inner portion of the cylindrical sleeve such that the spool valve forms a step portion. A gap communicates with the space between the movable and fixed cores, while at least one opening in the body of the spool valve communicates the interior of the spool valve with the step portion. An intermediate plate in the form of an annular plate with a plurality of radial grooves can be arranged between the main body and the sleeve.
