ABSTRACT:
A bifilar type pendulum automotive engine vibrational damper has at least one pendulum with an inner curved cam follower surface that is alternately engaged and disengaged from a pin type cam fixed on the pendulum carrier during low engine crankshaft operating speeds, such as during engine start up or shut-down, to force the pendulum to follow a path close to the path defined by the swinging arcuate movement of the pendulum during operation at normal engine crankshaft operating speeds, a minimal radial clearance being provided between the pendulum's curved surface and pin during the normal crankshaft operating speeds to reduce the impact of metal to metal contact between the pendulum and rollers or pendulum and carrier and resultant noise when the pendulum alternately falls inwardly against the carrier in response to gravity and then is forced outwardly due to centrifugal force.
