As the solenoid is switched on, the anchor lifts
up and makes the valve-body move to open the
valve.
When the valve-body reaches its stroke-end, a
bounce can occurs. The same negative effect
can occurs also in the closing phase of the valve,
when the ball comes in contact with the valve-
seat
The de-coupling of the anchor and the valve-
body reduces the risk of bouncing, thus a
positive effect on the drivability is obtained.
