摘要：
A rocker arm can comprise a cam arm, a valve arm, a lost motion spring, and a pair of deactivatable latches configured to impede travel of the cam arm with respect to the lost motion spring and configured to enable the cam arm to collapse the lost motion spring. The cam arm can comprise a cam interface, a spring pressing area, a cam arm body, and a pivot axle connection. The valve arm can comprise a valve arm body, a rocker shaft bore, a latch socket, and lost motion spring mount. A pivot axle can connect the valve arm body to the cam arm body. Alternatively, a latch socket in a valve arm neck comprises a latch assembly whereby a deactivatable latch is configured to impede motion of the cam arm and to collapse so the cam arm can collapse the lost motion spring
