Abstract
To reduce noise, impact forces and bouncing, the shaft of a rotary solenoid is provided with a dampening mechanism which generally includes a resilient dampening element and a cooperating collar which are axially disposed about the rotating shaft of the solenoid. Following activation of the rotary solenoid, the resilient element is drawn into contact with the housing, developing friction between the rotating resilient element and the housing of the rotary solenoid which operates to bring rotation of the shaft to a controlled stop.
