Abstract
A lever assembly for a flow regulator includes a damper to reduce unwanted movement of the lever in an opening and closing direction. The damper includes one or more resilient spring members that squeeze the lever with an amount of force sufficient to reduce unwanted pivoting of the lever without preventing the lever from pivoting in response to control movements of an actuator adapted to actuate the lever.
