Abstract

A pushrod assembly for an internal combustion engine comprises a pushrod having a first end and a second end, the first end being configured to receive valve actuation motions from a valve actuation motion source and the second end being configured to impart the valve actuation motions to a valve train component. The pushrod includes a resilient element engagement feature. The pushrod assembly includes a fixed support and a resilient element operatively connected to the resilient element engagement feature and the fixed support. The resilient element is configured to bias the pushrod, via the resilient element engagement feature, toward the valve actuation motion source. An internal combustion engine may comprise the pushrod assembly described herein. A follower assembly may be provided to maintain contact between second end of the pushrod and the valve train component.
