Claims

[Scope of utility model registration request]

In a solenoid valve in which a movable core is attracted to a fixed core against a spring when energized, and a valve body is attached to one end of the movable core via a valve stem, a plurality of axially extending parts are provided on the outside of the valve stem. A first ratchet member having grooves formed therein is rotatably and axially movable, and a plurality of teeth having inclined surfaces at upper and lower ends are spaced apart in the circumferential direction on the outer periphery of the lower end of the first ratchet member. annular second and third ratchet members that can be engaged with the first ratchet member are fixed in the valve body while being separated from each other in the axial direction of the valve stem, and the second ratchet member is fixed to the second ratchet member. has a plurality of downwardly inclined surfaces spaced apart in the circumferential direction that engage with the inclined surface at the upper end of the first ratchet member to cause rotation in the first ratchet member; a plurality of grooves capable of accommodating the teeth of the first ratchet member; and a plurality of upwardly directed inclined surfaces that engage with the inclined surfaces at the lower ends of the teeth to cause rotation of the first ratchet member. A self-retaining solenoid valve characterized in that the upwardly inclined surfaces are formed into two discontinuous parts that are alternately spaced apart in the circumferential direction.
