An inner cylinder is coaxially disposed within the inner cavity of the main body and is adapted to move relative to the main body. The inner cylinder has an open end adjacent the main aperture, and at least two sets of inner openings selectively matable with the openings in the main body upon movement of the inner cylinder with respect to the main body. By selecting the appropriate alignment of openings, varied amounts of resistance can be achieved.
