Oil communication manifold for an internal combustion engine

摘要

A cylinder head assembly for an internal combustion engine is provided having a cylinder head adapted to contain at least one switchable valvetrain element operable to selectively deactivate at least one intake valve and at least one other switchable valvetrain element operable to selectively deactivate at least one exhaust valve. The cylinder head defines at least one feed passage operable to selectively communicate fluid pressure to the at least one switchable valvetrain element to selectively deactivate the at least one intake valve. The cylinder head defines at least one other feed passage operable to selectively communicate fluid pressure to the at least one other switchable valvetrain element to selectively deactivate the at least one exhaust valve. An oil communication manifold is mounted to the head and defines at least one communication passage operable to enable communication of fluid pressure between the at least one feed passage and the at least one other feed passage.
