摘要:
A solenoid operated valve has a valve body forming a chamber provided with a valve seat at its center. A fluid port communicating to an aperture formed in the center of said valve seat and another fluid port communicating to said valve chamber through a passage. An electromagnet body of a ring shaped cross section is mounted to the valve body from above overlying the valve chamber. The electromagnet body is divided by a central yoke and an outer enclosure formed with an outer yoke at its end facing said valve chamber. The lower ends of said central yoke and that of said outer yoke have tightly fit therebetween a lower flange of a solenoid coil bobbin of inserted in the coil chamber, formed thereby and seals off the valve chamber from the coil chamber. A movable block having a valve located at its center within said valve chamber is, normally, forced downwards by way of a spring to close off said valve seat and is attracted, when said coil is energized, toward said central yoke and said outer yoke to open said valve seat.
