Abstract

A cam ring has lobes (15) engaged by a follower (14) to impair inward movement to a pump plunger. The cam lobe has a trailing flank which includes a first sloping portion (48) an intermediate portion (47) during which the plunger remains stationary and a second sloping portion which is shaped to correspond with the natural flight path (51) of the follower. Just before the cam follower contacts the base circle, the second sloping portion departs from the natural flight path so that the follower contacts the cam ring base circle as smoothly as possible.
