<p>PURPOSE:To prevent a valve body from sticking by furnishing a major dia. part with large bore in a cylinder accommodating the valve body, and allowing deposits to precipitate on this major dia. part. CONSTITUTION:A flow control valve has a valve body 41 to advance and retract in accordance with the amount of current supply to a solenoid and a cylinder 32 having a fluid flowing hole 31 at the circumferential wall so as to control the opening in this fluid flowing hole 31. A large dia. part 32a is formed, wherein the bore of cylinder 32 on the fluid flowing end side shall be greater than the other parts. It is also acceptable if a minor dia. part is formed at the valve body 41 in lieu of the major dia. part 32a.</p> |
