INTEGRATED PRIMARY AND AUXILIARY VALVE ACTUATION SYSTEM

摘要

A system (10) and method for actuating at least one engine valve (200) in an internal combustion engine to produce an engine valve event is disclosed. The system of the present invention may comprise means (100) for imparting motion to the at least one engine valve (200) for producing the engine valve event; primary means (300) for transmitting the motion from the motion imparting means (100) to the at least one engine valve (200); and auxiliary means (125) for transmitting the motion from the motion imparting means (100) to the at least one engine valve (200). The auxiliary means (125) may actuate the at least one engine valve (200) only when the primary means (300) is shut-off or fails.
