SOLENOID VALVE

摘要

Disclosed is a solenoid valve. In a solenoid section (22) forming part of a solenoid valve (10), a sleeve (40) is provided on the inner circumferential side of a bobbin (36) around which a coil (34) is wound. This sleeve (40) is formed from magnetic material and has a cylindrical section (46) and a flange section (48) formed at the lower end of the cylindrical section (46). At the upper end of the cylindrical section (46), a tapered section (50) is formed in which the outer circumferential face is recessed in the radially inward direction. The tapered section (50) is arranged facing and in close contact with the outer circumferential face of a fixed core (38) such that the magnetic flux density in the tapered section (50) increases when the solenoid section (22) is excited.
