Abstract:
1. A hydraulic valve actuator system for an internal combustion engine having at least one spring-biased valve movable between a closed position and an open position and a pressurized oil lubrication system, the hydraulic valve actuator system comprising: an actuator assembly disposed at a first location relative to at least one spring-biased valve of an internal combustion engine, the actuator assembly including a hydraulic pipe having a distal end in fluid connection with the outlet port of the actuator assembly and a proximal end; and a valve follower assembly disposed at a second location relative to the at least one spring-biased valve, the second location being spaced-apart from the first location and closer to the at least one spring-biased valve than the first location, the valve follower assembly including wherein the fluid control device of the actuator assembly comprises: a flow control housing defining an interior cavity, an inlet port and an outlet port; a shuttle slidably disposed in the interior cavity of the flow control housing so as to be movable between at least two configurations, the shuttle having a cross-passage thereupon; wherein, when the shuttle is in one of the at least two configurations, the cross-passage of the shuttle is positioned so as to put the inlet port in fluid communication with the outlet port; and wherein, when the shuttle is in the other of the at least two configurations, the cross-passage of the shuttle is positioned so as to block fluid communication between the inlet port and the outlet port.
