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 16):
A method of manufacturing a linear solenoid valve, the linear solenoid valve comprising: 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, and a thick portion larger in thickness than the thin portion; 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 and that supports the movable element slidably in the axial direction; and a second stator aligned with the first stator in the axial direction, the method comprising:\n a core forming step of integrally forming the first stator and the second stator such that a part of the first stator in the axial direction is formed as a large diameter portion, such that another part of the first stator that is located closer to the second stator than the large diameter portion in the axial direction is formed as a small diameter portion, such that a part of the second stator is formed as a supporting portion, and such that an outside diameter of the small diameter portion is at least partially smaller in a circumferential direction than each of an outside diameter of the large diameter portion and an outside diameter of the supporting portion; a coil disposing step of disposing the coil radially outside the first stator and the second stator such that an inner peripheral surface of the bobbin is supported by an outer peripheral surface of the supporting portion, such that an inner peripheral surface of the thick portion of the bobbin is supported by an outer peripheral surface of the large diameter portion, and such that at least a part of the coil in the axial direction overlaps the small diameter portion 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 of the bobbin; and a resin layer forming step of forming a resin layer by filling an outer periphery of the coil with a non-magnetic resin material.
