Abstract
A follower mechanism movable along an axis within a bore including an alignment groove. The follower mechanism includes a bucket with a cylindrical inner surface and a cylindrical outer surface, and a yoke positioned at least partially within the bucket, the yoke including a bottom wall and two opposed sidewalls depending upwardly therefrom, each sidewall defining a shaft aperture. A shaft with first and second ends is received in the shaft apertures, and a roller follower is rotatably received on the shaft such that a portion of the roller follower extends axially outwardly beyond the bucket.

A follower mechanism movable along an axis within a bore including an alignment groove, comprising:
- a bucket including a cylindrical inner surface and a cylindrical outer surface;
- a yoke positioned at least partially within the bucket, the yoke including a bottom wall and two opposed sidewalls depending upwardly therefrom, each sidewall defining a shaft aperture;
- a shaft having first and second ends received in the shaft apertures;
- and
- a roller follower rotatably received on the shaft such that a portion of the roller follower extends axially outwardly beyond the bucket.
A follower mechanism movable along an axis within a bore including a alignment groove, comprising:
- a bucket including a cylindrical inner surface, a cylindrical outer surface, and defining an aperture, the aperture having a length parallel to the axis and a width transverse to the axis;
- and
- an alignment device positioned at least partially within the aperture, the alignment device having a length parallel to the axis and a width transverse to the axis,
- wherein a maximum length of the aperture is greater than a maximum length of the alignment device and a maximum width of the aperture is greater than a maximum width of the alignment device.
A follower mechanism movable along an axis within a bore including a alignment groove, comprising:
- a bucket including a cylindrical inner surface, a cylindrical outer surface, and defining an aperture, the aperture having a length parallel to the axis and a width transverse to the axis;
- and
- an alignment device positioned at least partially within the aperture, the alignment device having a length parallel to the axis and a width transverse to the axis,
- wherein the alignment device has a generally rectangular cross-sectional shape when taken through a plane in which both a longitudinal center axis of the alignment device and the axis of the bore lie.
