    摘要： An electromagnetic linear valve includes: (a) a plunger including a large outside-diameter portion and a small outside-diameter portion, and (b) a housing having a through-hole and including a large inside-diameter portion in which the large outside-diameter portion is inserted with a clearance being defined between the large inside-diameter portion and the large outside-diameter portion, and a small inside-diameter portion in which the small outside-diameter portion is inserted with a clearance being defined between the small inside-diameter portion and the outside-diameter portion. The plunger has an end portion which serves as a valve body that is to be seated on a valve seat constituted by an opening of the through-hole. The large outside-diameter portion has an end portion constituted by another end portion of the plunger that is opposite to the above-described end portion of the plunger. The clearance between the small inside-diameter portion and the small outside-diameter portion is smaller than the clearance between the large inside-diameter portion and the large outside-diameter portion.

    摘要： An electromagnetic linear valve which can effectively suppress a self-excited oscillation of a plunger is provided. A resilient member 64 urges a plunger 22 in a direction in which the core-opposing portions 70, 78 move away from a core portion 28, and moves the plunger 22 in a direction in which the core-opposing portions 70, 78 approach the core portion 28 in the case where an electric current is supplied to a coil 24. In the case where no electric current is supplied to the coil 24, a radially opposing surface area Sr as a surface area of portions of the core-opposing portions 70, 78 which respectively oppose inner peripheral surfaces of recessed portions 74, 76 is smaller than an axially opposing surface area St as a surface area of portions of the core-opposing portions 70, 78 which respectively oppose bottom surfaces of the recessed portions 74, 76, and the radially opposing surface area Sr becomes larger than the axially opposing surface area St in the case where an electric current is supplied to the coil 24 and the core-opposing portions 70, 78 approach most to the core portion 28.

    摘要： A normally closed solenoid valve (100) includes a housing (10), and a valve element (21), a movable core (22), a first spring (23), a second spring (24), a coil (25), a stator core (26), and other components, which are assembled to the housing (10). The valve element (21) is arranged so as to be seatable on and unseatable from a valve seat (12c). The movable core (22) is assembled to a cylinder section (11b) of the housing (10) so as to be movable integrally with the valve element (21) in an axial direction of the movable core (22). The first spring (23) is configured to bias the valve element (21) and the movable core (22) toward the valve seat (12c). The coil (25) and the stator core (26) are configured to generate an electromagnetic force resistive to a load of the first spring (23) for the movable core (22) through energization of the coil (25). The second spring (24) is configured to apply a load smaller than and resistive to the load of the first spring (23) to the valve element (21) and the movable core (22). The normally closed solenoid valve (100) further includes a load adjusting mechanism capable of adjusting the load of the first spring (23), and a stroke adjusting mechanism capable of adjusting an unseating stroke of the valve element (21) from the valve seat (12c).

    摘要： An electromagnetic valve includes a housing, a valve element, a movable core, a spring, a coil, and a stationary core. The housing includes a cylinder portion that houses the movable core so that the movable core is movable in an axial direction. An axial intermediate portion of the cylinder portion is formed as a non-magnetic portion that surrounds an outer circumference of an axial intermediate portion of the movable core. Both axial sides of the non-magnetic portion are formed as a one-side magnetic portion and an another-side magnetic portion that surround an outer circumference of the movable core. An electromagnetic force in a direction perpendicular to the axial direction, for generating a friction resistance to axial movement of the movable core, is set to be generated by energization of the coil between the outer circumference of the movable core and the one-side magnetic portion of the cylinder portion on one axial side of the non-magnetic portion and between the outer circumference of the movable core and the another-side magnetic portion of the cylinder portion on another axial side of the non-magnetic portion.
