Title:
ソレノイドエアーバルブ
Document Type and Number:
Japanese Patent JP4576908
Kind Code:
B2
Abstract:
A moving core (120) of a solenoid air valve has a flange portion (122) arranged on a side of a fixed core (110), provided in a radially projecting manner and having a first diameter, and a shaft portion (121) having a second diameter smaller than the first diameter. Therefore, a sufficient area of magnetic pole is ensured around a rubber packing (150) in the flange portion (122) of the moving core (120). Consequently, the solenoid air valve structured such that an area of magnetic pole is sufficiently ensured even if the moving core is made thinner in order to ensure a volume of a coil body in reducing the solenoid air valve in size can be provided.
