ABSTRACT:
In a spool-sleeve type electromagnetic change-over valve the dimension of the non-valving holes in the axial direction of the sleeve is made considerably larger than the comparable dimension of the valving holes and the total area of a row of the non-valving holes is similarly made much larger than a row of the valving holes so that the spool stroke is kept small while increasing the air flow capacity of the valve.
