Claim Text:
1. A device for effecting an axial shift of a rotary shaft comprising: a first component having a shaft and a head; a second component having a first end and a second end and a bore extending longitudinally therethrough, the first end of the second component being countersunk so as to define inclined ramps in walls as a portion of the second component; the shaft of the first component being inserted into the bore of the second component; a detent for coupling the first component to the second component such that rotation of the second component causes the first component to rotate; one or more rollers disposed in between the head of the first component and the first end of the second component in rolling contact with the inclined ramps; the device being configured such that as the second component is rotated about a longitudinal axis the rollers move along the inclined ramps and act upon the first component to move it axially with respect to the second component; and wherein the detent comprises a groove and a bearing seated therein, the groove arranged to effect a rotation of the first component with respect to the second component as the first component is moved axially with respect to the second component.
