ABSTRACT:
A snap-on type spring retainer lock comprises a one-piece stamped retainer element which has resilient spring fingers which encircle and clamp against a tapered surface portion of a valve stem. A spring retainer is held on the valve stem by the abutting engagement of the spring retainer with the retainer lock. The retainer lock has a base portion from which the spring fingers project. The base portion is adapted to cover the tip end of the valve stem and acts as a bearing surface for a mechanism for driving the valve.
