Title:
LINEAR SOLENOID VALVE AND METHOD FOR MANUFACTURING LINEAR SOLENOID VALVE
Document Type and Number:
WIPO Patent Application WO/2017/056919
Kind Code:
A1
Abstract:
In this linear solenoid valve, a coil (12) wound around a bobbin (13a) is disposed on the external peripheral sides of a first core (15) and second core (16) constituting part of a core part (17), and the coil (12) and the core part (17) are integrally molded by forming a cover part (13b) from a resin material filled into the external peripheral side of the coil (12). The first core (15) has a small-diameter part (15A) which has an outside diameter r2 smaller than the outside diameter r1 of an outer cylindrical part (32b) of the second core (16) that faces the coil (12), and a large-diameter part (15B) which has an outside diameter r3 larger than the small-diameter part (15A). The diametrally inward pressing of the first core (15) via the bobbin (13a) when the cover part (13b) is formed is reduced by the space between the small-diameter part (15A) and the bobbin (13a).
