Abstract:
In a linear solenoid valve, a coil wound on a bobbin is disposed radially outside a first core and a second core of that configure a part of a core segment, and a cover portion is formed by filling the outer periphery of the coil with a resin material so that the coil and the core segment are integrally molded together. The first core includes a small diameter portion having an outside diameter r 2  smaller than an outside diameter r 1  of an outer tubular portion that is part of the second core and that is opposed to the coil, and a large diameter portion that has an outside diameter r 3  larger than that of the small diameter portion. A space between the small diameter portion and the bobbin makes it less likely that the first core is pressed radially inward via the bobbin during formation of the cover portion.

Claim (Index 7):
A linear solenoid valve comprising:\n a spool that slides inside a hollow cylindrical sleeve in an axial direction to cause valve opening and valve closing; a coil; a tubular bobbin including a thin portion having an outer peripheral surface on which the coil is wound, a thick portion larger in thickness than the thin portion, and an opening that is defined by inner peripheries of the thin portion and the thick portion and that faces in the axial direction; a movable element that is a magnetic member and that is driven to move in the axial direction upon energization of the coil so as to move the spool; a first stator that is a magnetic member, that is disposed radially inside the coil, and that supports the movable element slidably in the axial direction; a second stator that is disposed radially inside the coil and that is aligned with the first stator in the axial direction; and a resin layer formed on an outer periphery of the coil, wherein the second stator includes a supporting portion having an outer peripheral surface that supports an inner peripheral surface of the bobbin, the first stator includes a large diameter portion and a small diameter portion, the large diameter portion has an outer peripheral surface that supports an inner peripheral surface of the thick portion of the bobbin, the small diameter portion is located between the supporting portion and the large diameter portion in the axial direction and is at least partially smaller in outside diameter in a circumferential direction than the large diameter portion and the supporting portion, and at least a part of the small diameter portion in the axial direction overlaps the thin portion of the bobbin as seen from a radial direction so as to form a clearance between an outer peripheral surface of the small diameter portion and an inner peripheral surface of the thin portion.
