Abstract
A solenoid valve includes a body having a flow channel, and a solenoid part coupled to the body. The solenoid part includes a core housing. A movable core can be accommodated inside the core housing. A flange part of the core housing is expanded radially outwardly from a guide part which guides the movable core. Further, a thick portion is provided at a boundary portion between the flange part and the guide part on a core part side. The thick portion becomes gradually thick toward the guide part.
Claims3
A solenoid valve comprising:
- a body including a flow channel as a passage of fluid;
- a movable core provided movably relative to the body;
- a solenoid coupled to the body, and configured to move the movable core in an axial direction when the solenoid is excited by energization;
- a fixed member provided inside the solenoid, and made of magnetic material;
- and
- a valve plug provided at an end of the movable core, and configured to switch a communication state of the flow channel,
- wherein the fixed member includes:
- a tubular guide part in which the movable core is movably accommodated;
- a core part extending coaxially with and continuous with the guide part, the core part being configured to attract the movable core by excitation of the solenoid;
- and
- a flange part expanded radially outwardly from the guide part,
- wherein a thick portion is provided on a boundary portion between the flange part and the guide part.
