Abstract
The lost motion arm 44 has first and second contact surfaces,and,A latch mechanism is connected on the body with an extendable plunger,having a first contact surface,and a second contact surface,The plunger,has a first position for first contact surface,engagement with the lost motion arm first contact surface,to prevent angular movement of the lost motion arm,with respect to the body,in a first angular direction. When angular movement in the first angular direction is prevented, the motion of the lost motion arm,imparted by the cam lobe,is transmitted to the body,to provide for a first state of operation of the valve stem,When the plunger,is in a second position, non-contacting with the lost motion arm,the lost motion arm,is allowed to pivot relative to the body,Accordingly, the rocker arm assembly,will be in a second state of total or partial deactivation of the valve stem,The plunger second contact surface,contacts with the lost motion arm second contact surface,to cause the plunger,to be cammed out of the first position when the plunger,is in the first position and when the plunger first contact surface,is not engaged with the lost motion arm's first contact surface
