<p>PURPOSE:To prevent aberration or fall of magnetic poles used for a solenoid valve which is applicable to a feed or distribution valve, by setting a pair of poles between the external circumference of a plunger guide with a built-in plunger and the internal circumference of a coil bobbine and providing the coil bobbine with a rib located between both magnetic poles. CONSTITUTION:An annular rib 10 is formed between a pair of magnetic poles 5a, 5b on the internal furface of a coil bobbine 3 and along the external circumference of a plunger guide 4. High water pressure put in the plunger guide 4 is inhibited, due to the construction, by the rib 10 to expand inside or outside of the plunger 6, and leak of water due to damage of the plunger guide 4 or due to abrasion of the plunger 6 is prevented. The assembly is easy, because aberration of the magnetic poles 5a, 5b is eliminated by simply keeping the end face of the poles in touch with the end face of the rib 10.</p> |
