摘要： A system for actuating an engine valve is disclosed. The system may include a rocker shaft having a hydraulic fluid supply circuit extending through the rocker shaft to a port on the outer surface of the rocker shaft and a solenoid valve adapted to selectively supply hydraulic fluid to the rocker shaft hydraulic fluid supply circuit. The rocker shaft may be supported by one or more rocker shaft pedestals. A lost motion housing may be incorporated into a rocker shaft pedestal and disposed about the rocker shaft. The lost motion housing may have an actuator piston assembly and a control valve assembly connected by an internal hydraulic circuit. The lost motion housing may be secured in a fixed position relative to the rocker shaft. External hydraulic fluid tubing may be provided between the solenoid valve and the control valve in the form of jumper tubes extending between adjacent rocker shafts or in the form of external hydraulic fluid tubes extending from control valve to control valve.
