ABSTRACT:
A direct-acting electromagnetic valve which is arranged to apply balanced fluid pressures to the opposite ends of a valve body 10 while ensuring smooth and stabilized movements of the valve body 10 in switching operations. For these purposes, a couple of cheers 16 and 17 which are formed in association with the opposite ends of the valve body 10 are communicated with each other by way of an axial through hole 12 within the valve body, and guide rings 15 are provided on the opposite end portions of the valve body 10 to guide its sliding movements. Gap spaces 15a are formed in these guide rings 15 to communicate the two chambers 16 and 17 with valve bore portions where exhaust ports EA and EB are opened.
