ABSTRACT:
An electromagnetic valve uses a solenoid coil to produce a magnetic attraction of a cylindrical shell core against the action of a spring. A valve seat is constituted by a plate of a hard material arranged to cooperate with a circular ridge on an end of the core to obtain an hermetic seal therebetween. The plate is maintained against a bearing surface within a valve housing by a telescoping element located within the shell core and providing a sliding support surface for the shell core.
