Abstract
A device includes an outer cylinder having a cylinder inner wall and a cylinder outer wall and at least one magnet disposed on or between the cylinder inner wall and the cylinder outer wall and a piston having a piston inner wall and a piston outer wall and at least one magnet disposed on or between the piston outer wall and the piston inner wall. In one embodiment, the piston is rotatable within the cylinder and slidably movable along an axis respective to the cylinder. The piston is also disposed within the cylinder such that the at least one magnet disposed on or between the cylinder inner wall and the cylinder outer wall is aligned with the at least one magnet disposed on or between the piston outer wall and the piston inner wall, substantially preventing the piston from rotating relative to the cylinder.
