Title:
ELECTROMAGNETIC VALVE ACTUATOR SYSTEM
Document Type and Number:
Japanese Patent JP2005176595
Kind Code:
A
Abstract:

To simplify a structure and suppress an increase in NVH (noise, vibration and harshness in operation).

An electromagnetic valve actuator system is provided with a reciprocating valve having a valve stem 42 with a valve head 44 at one end, a first electromagnetic coil 51 disposed on a first laminated iron core 52 and having a gap 55, a second electromagnetic coil 53 disposed on a second laminated iron core 54 and having a gap 55' aligned with the gap 55, and an armature 50 provided on the valve stem 42. When the armature 50 is disposed in the center of the gap 55 of the first laminated iron core 52 or the gap 55' of the second laminated iron core 54, the armature 50 is inserted into the gap 55 of the first laminated iron core 52 and the gap 55' of the second laminated iron core 54 and reciprocates along with the valve stem 42, so as to slightly protrude a part of the armature 50 from the thickness of the first laminated iron core 52 or the second laminated iron core 54.
