Abstract
A valve train assembly includes: at least one dual body rocker arm having a first body, a second body, a latching arrangement for latching and unlatching the first body and the second body, the latching arrangement having a latching pin that is biased to an unlatched configuration; and an actuator arrangement for controlling the latching arrangement, the actuator arrangement being able to contact the latching arrangement to cause the latching pin to be moved into a latched configuration in which it latches the first and second bodies together. In use, movement of the rocker arm under action of a cam to cause a valve event moves the actuator arrangement out of contact with the latching arrangement while a contact force between the latching pin and one or other of the first and second bodies maintains the latching pin in the latched configuration.
