Abstract: A device for reducing the resonant vibrations of a helical valve spring of an internal combustion engine includes a member, such as a tension cable, attached between one end of the spring and a coil mid-section of the spring for limiting the movement of the coil mid-section away from the one end of the spring to about the distance between the coil mid-section and the one end of the spring when the spring is in a condition corresponding with a condition at which the spring is in static equilibrium.
