ABSTRACT:
The present invention is directed to a start-up system for an engine valve actuation assembly. The start-up system may comprise a removal assembly for removing at least one of air and debris from the engine valve actuation assembly during an engine start up operation. The removal assembly may include a supply assembly for supplying fluid to the engine valve actuation assembly under high pressure to remove at least one of air and debris from the engine valve actuation assembly. The supply assembly may include a storage assembly for storing a supply of hydraulic fluid, and a fluid supply assembly for supplying fluid to the storage assembly. The fluid may be supplied under pressure from the storage assembly to the engine valve actuation assembly. Furthermore, the fluid may be supplied under an influence of gravity from the storage assembly to the engine valve actuation assembly.
