<p>In a cam apparatus (1) there is included a cam means (3) rotatable with the aid of a drive shaft (2), said means with its flank coacting with a movable follower (5) to control the movement of the latter as a function of the rotation of the cam means. Two cam members (7, 8) incorporated in the cam means surround the drive shaft (2) and are each in non-rotatable engagement therewith via a guide means (21). By axial displacement between the drive shaft and the cam members there is obtained relative displacement in the peripheral direction between drive shaft and cam members. In this manner the shape of the cam means can be varied.</p> |
