Abstract
The switchable dual lifter has two hydraulic lash adjusters, one which is fixed within the common housing, and the other which is movable to allow for deactivation of one of the two valves acted on by the dual lifter. Using the dual lifter with a switchable hydraulic lash adjuster allows for closing of one of the adjacent valves while allowing the other of the adjacent valves to operate.
