??? Look, this tubular lifter has nothing special, it just has a loose skirt moving under internal forces. Think of the paddle wheel having a loose axle. The axle will jump forward, trying to leave the boat behind, when you engage the clutch in "forward gear", and then will stay there as long as the boat pushes on its paddles. Very much the same, very prosaic.
