Zusammenfassung:A rocker arm assembly includes an engine brake capsule assembly. The engine brake capsule assembly is movable between a retracted position and an extended position to selectively engage a valve bridge to open a first exhaust valve. The engine brake capsule assembly includes an outer housing including a lower chamber and a plunger. The plunger extends out below the outer housing. The engine brake capsule assembly further includes a check ball valve assembly disposed within the lower chamber configured to selectively enable a hydraulic fluid into the lower chamber and an oil channel fluidly coupled to the lower chamber and configured to direct a flow of the hydraulic fluid out of the lower chamber. The engine brake capsule assembly further includes a spool valve configured to selectively block the oil channel.
