<p>A solenoid valve. In a solenoid section forming part of the solenoid valve, a sleeve is provided on the inner circumferential side of a bobbin around which a coil is wound. This sleeve is formed from magnetic material and includes a cylindrical section and a flange section formed at a lower end of the cylindrical section. At an upper end of the cylindrical section, a tapered section is formed in which an outer circumferential face is recessed in the radially inward direction. The tapered section is arranged facing and in close contact with the outer circumferential face of a fixed core such that the magnetic flux density in the tapered section increases when the solenoid section is excited.</p> |
