Abstract
A collapsible valve bridge actuation system that is configured to alter the lift of poppet valves in a reciprocating piston machine cylinder. The system has a rocker arm configured to be actuated by a cam lobe, and a collapsible valve bridge device that is functionally attached to the rocker arm. The device has a deactivation assembly that contains lock pins within a housing and springs. Also, the device is configured to remain rigid, partially collapse, or fully collapse. The extent of collapse is a function of the strength of the springs.
