Document Type and Number:
WIPO Patent Application WO/2022/097514
Kind Code:
A1
Abstract:
Provided is a solenoid valve capable of obtaining a thrust of a movable iron core in proportion to a current value applied to a coil. This solenoid valve 1 comprises: a movable iron core 4; a solenoid formed body 31 disposed on the outer diameter side of the movable iron core 4 and having a coil 34; a solenoid case 30 in which the movable iron core 4 and the solenoid formed body 31 are accommodated; a fixed iron core 32 that is disposed on the inner diameter side of the solenoid formed body 31 and generates a magnetic force between the fixed iron core 32 and the movable iron core 4 via the electrification of the coil 34; and a valve part 2 that opens or closes a flow path by moving the movable iron core 4, wherein a magnetic material 8 separate from the solenoid case 30 is disposed at an axial end of the coil 34 outside the solenoid case 30.
