Abstract
A contact bounce reduction system including: a movable member, and a contact bounce damping device including: a body, a first ball and a second ball, a first resilient member and a second resilient member, a piston. The first resilient member holds the first ball in the seat and the second resilient member holds the second ball in the seat when the piston is in a default extended position, and a third resilient member biases the piston towards the default extended position. The movable member actuates the piston towards the retracted position, causing the first ball and the second ball to move radially out from the seat, and the third resilient member to accumulate energy.
