[Also in Division F4] An adjustable profile cam employed in an air conditioning unit (see Division F4) comprises two plates 53a, 55 linked by a spring 62. On counter-clockwise rotation of the cam, the follower 57a follows the profile shown, but on clockwise rotation the follower abuts against the surface 70a of plate 55, and moves this relative to plate 53a against the spring 62 until a screw 67 on the plate 53a abuts against a projection 66 on the plate 55.
