Abstract (en)
A cylinder head assembly includes a cylinder head defining a port for selectively communicating air to a combustion chamber of an engine or for selectively discharging exhaust gases from the combustion chamber. The cylinder head also defines a valve seat between the port and the combustion chamber. A combustion valve is mounted in the cylinder head and is selectively seated and unseated with the valve seat. A camshaft with a lobe is mounted in the cylinder head. A rocker arm is engaged with the combustion valve and has a follower for following the lobe. An oil spray source provides a spray of oil while an oil reflector is configured to receive the spray of oil and direct the spray of oil to the follower to provide lubrication between the interface of the follower and the lobe.
