INTEGRATED MASTER-SLAVE PISTONS FOR ACTUATING ENGINE VALVES |
摘要 |
An apparatus for actuating first and second engine valves comprises a rocker arm that receives motion from primary and auxiliary valve actuation motion sources at a motion receiving end of the rocker arm. A master piston residing in a master piston bore in the rocker arm is configured to received motion from the auxiliary valve actuation motion source. A slave piston residing in a slave piston bore in the rocker arm is configured to provide auxiliary valve actuation motion to the first engine valve. A hydraulic circuit is provided in the rocker arm connecting the master piston bore and the slave piston bore, and a check valve is disposed within the rocker arm, configured to supply hydraulic fluid to the hydraulic circuit. The apparatus may be incorporated into a system comprising a rocker arm shaft and the primary and secondary valve actuation motion sources, such as an internal combustion engine. |
