Abstract
A biasing device for a free rocker arm in an engine valve actuating system wherein driven rocker arms are selectively engaged with the free rocker arm to provide variable valve operating characteristics. The biasing device includes interfitting, cold-formed cup-shaped members within which a compression spring is received in interference fit at one end with the body and at the other end with the plunger. In a preferred embodiment, at least two coils of the spring are in interference fit with the body to provide spring damping.
