Abstract
An electromagnetic linear valve which can effectively suppress a self-excited oscillation of a plunger is provided. A resilient memberurges a plungerin a direction in which the core-opposing portionsmove away from a core portionand moves the plungerin a direction in which the core-opposing portionsapproach the core portionin the case where an electric current is supplied to a coilIn the case where no electric current is supplied to the coila radially opposing surface area Sr as a surface area of portions of the core-opposing portionswhich respectively oppose inner peripheral surfaces of recessed portionsis smaller than an axially opposing surface area St as a surface area of portions of the core-opposing portionswhich respectively oppose bottom surfaces of the recessed portionsand 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 coiland the core-opposing portionsapproach most to the core portion
