Electromagnetic Actuator

摘要

[Means to Solve Problem] A coil (68) is housed in a main body (70). An inner cylindrical portion (98a) is disposed inward of the coil (68). An armature (80) adapted to be attracted by the coil (68) is disposed, being spaced from the inner cylindrical portion (98a). A magnetic flux concentrating member (100) is disposed on the side of the coil (68) nearer to the armature (80), being spaced from the inner cylindrical portion (98a). The gap between the inner cylindrical portion (98a) and the magnetic flux concentrating member (100) is larger than the gap between the armature (80) and the inner cylindrical member (100).

主权项

1. An electromagnetic actuator comprising:
a main body; a coil housed in said main body; a first magnetic member disposed inward of said coil an armature adapted to be attracted by said coil, and disposed with a gap disposed between said first magnetic member and said armature; a second magnetic member disposed on an armature side of said coil with a gap disposed between said second magnetic member and said first magnetic member; and an actuating part formed integral with said armature; said gap between said first magnetic member and said second magnetic member being larger than said gap between said armature and said first magnetic member.
