Abstract
A proportional solenoid, capable of linear motion, includes an electromagnetic valve device including a solenoid assembly having a mobile core, a push rod connecting the solenoid mobile core to a valve plunger, and a device operable to apply a controlled friction force to hold the mobile core in an intermediate position. The friction force applied by the friction device is greater than the motive forces generated by the solenoid.
