Abstract: In one embodiment, a system for synchronizing switching comprises a first body coupled to a pressurized fluid supply and a control fluid supply, and a second body comprising a spool valve that is configured to be contained within a spool valve housing and movable between an open position and a closed position, a biasing element that is configured to bias the spool valve, and at least three fluid channels that are configured to be fluidly connected to the spool valve housing. The first body and the second body are configured for relative movement to each other. The spool valve is further configured to selectively control fluid communication among the fluid channels based on relative movement between the first body and the second body.

Abstract: 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.
