Title: Solenoid valve
Inventor: YOSHIMURA SHUICHI
IPC: F16K31/06
Filed: 1988-08-26
Abstract: PURPOSE:To eliminate the contacting sound of a movable valve body with the suction end of a fixed iron core by composing in such a way that a movable iron core is received leaving an air gap from the suction end of the fixed iron core at the final stage of a suction stroke. CONSTITUTION:If a movable valve body 9 is magnetically sucked by a fixed iron core 6, a compression spring 22 is compressed to reach its compression limit with the winds of the compression spring 22 contacting with each other at a position where the movable valve body 9 has only a small air gap left from a suction end 6a at the final stage of a suction stroke. The movable valve body 9 is thus received leaving a small distance from the suction end 6a of the fixed iron core 6 for an air gap, though it is at a restoration position, at the final stage of magnetic suction, so their contacting with each other is prohibited. For the compression spring 22, the winds are contacting with each other at this time, but because a number of winds are contacting with each other at the same time, and as coating of synthetic resin exists between them, production of contacting sound is reduced.
