Abstract: A rocker arm includes a follower which follows a first lobe of a camshaft and is mounted to a rocker arm body; a lock pin that is selectively moveable in a lock bore between a first position and a second position in order to prevent relative movement between the rocker arm body and the follower in one of the first position and the second position and to permit relative movement between the rocker arm body and the follower in the other of the first position and the second position; and a rocker arm oil passage in fluid communication with the lock bore for communicating oil therethrough to move the lock pin between the first position and the second position. The rocker arm oil passage is elongated in a circumferential direction relative to the lock bore.

Abstract: 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.
