Title:
ソレノイドエアーバルブ
Document Type and Number:
Japanese Patent JP4576906
Kind Code:
B2
Abstract:
According to a solenoid air valve, a flange portion (122) of a moving core (120) and a flange portion area (142) of a bobbin (140) implement a stop area defining a distance of travel of the moving core (120) in a direction away from a fixed core (110). An end portion of a shaft portion (121) of the moving core (120) can project outward through an opening (103a) of a frame cover (103), so that a gap between a surface of the frame cover facing the shaft portion (121) and a side surface of the shaft portion (121) (distance: L2) can be minimized. Consequently, a solenoid air valve having a structure allowing improvement in magnetic efficiency by making smaller the gap between the frame and the moving core is provided.
