Abstract
A lost motion mechanism can comprise a castellation device, comprising a casing, an upper castellation, and a lower castellation. The casing can comprise a first linear slot and a second linear slot perpendicular to the first linear slot. Upper castellation can comprise an upper body, spaced upper teeth extending from the upper body, the spaced upper teeth forming spaced upper gaps therebetween, and an actuation peg extending from the upper body into the first linear slot. Lower castellation can comprise a lower body, spaced lower teeth extending from the lower body, the spaced lower teeth forming spaced lower gaps therebetween, and an anti-rotation peg extending from the lower body into the second linear slot. An actuator can be configured with the lost motion mechanism so that a movable arm comprises a forked end configured to move on the actuation peg as the movable arm swivels.
