The "ratchet spring~~" (this is all my nomenclature)~~ just keeps the ball bearing race in contact with the "tension rod" and the "tapered bore" (inside surface of tensioner housing). In the drawing the pink is the housing (metal) and the purple is the bore (absence of metal) and the inside surface is at the edge of the purple area. The washer in the diagram represents the bearing cage. Its purpose is to keep the bearings distributed around the rod and to transfer the force of the "ratchet spring" to the bearings, pushing them toward the narrow end of the taper.

When the rod moves out (left in the diagram) the bearings roll toward the wider end of the tapered bore. At some point they will lose contact with either the rod surface or the bore surface, will slip, and will be pushed back in contact by the "ratchet spring". Hence the rod can move out with essentially no resistance.

When the rod moves in (right in the diagram) the bearings roll toward the narrow end of the tapered bore. They won't be able to go far before the space between the rod and the tapered bore is smaller than the bearings and they get wedged into this decreasing space preventing the rod from moving further in (unless something slides instead of rolls).
