Abstract
A hollow rocker shaft including a central opening defined by a radially inner surface and a separator secured in the central opening of the rocker shaft is provided. A radially outer surface of the separator engages the radially inner surface of the rocker shaft via a press-fit. The separator divides the central opening of the rocker shaft into (1) a first chamber extending between a first chamber axial end and the separator, and (2) a second chamber extending between a second chamber axial end and the separator. The separator includes an orifice defined between the first chamber and the second chamber that provides fluid connection between the first chamber and the second chamber.
