LOW NOISE SOLENOID DEVICE

摘要

PURPOSE: A low noise solenoid device is provided to relieve a shock by making the same polarity coils face each other in a winding direction. CONSTITUTION: A bobbin(11) includes a hollow part passing through an upper and a lower part. The outer part of the bobbin is wound with a coil. A plunger(12) is movably formed in the hollow part. The outer part of the bobbin has two regions(11A,11B). The coil winding direction of one region is opposite to the coil winding direction of the other region.
