A linear solenoid valve includes a solenoid having a coil wound around a coil bobbin, a fixed core, and a movable core for being attracted to the fixed core when the coil is energized, and a valve mechanism having a valve element for selectively bringing an inlet port and an outlet port into and out of fluid communication with each other responsive to a displacement of the movable core. The movable core has a nonmagnetic layer formed on an outer surface thereof and having a predetermined thickness.
A linear solenoid is disclosed that includes a coil that generates magnetic force due to transmission of current therethrough. The linear solenoid also includes a plunger with an end face, a stator that movably supports the plunger, and a yoke including a bottom face. Furthermore, a biasing member is included that biases the plunger in a first direction along the axis. The stator magnetically attracts the plunger when current is transmitted through the coil so as to move the plunger in a second direction along the axis opposite to the first direction. Also, when current transmission through the coil is stopped, the biasing member biases the plunger to abut the bottom face of the yoke at least one abutted portion. Also a non-contact portion is included between the abutted portions where the plunger and the stator are spaced away from each other in the direction of the axis.
