Abstract
A downhole tool comprises a cylinder, piston, and piston rod, the piston rod comprising first and second ends, the first end being external to the cylinder and having the capacity to be operatively connected to a sucker rod string or a sucker rod pump, the second end being positioned within a sealed cylinder chamber and attached directly or indirectly to the piston. The cylinder confining fluid within the cylinder chamber. The piston is coaxially positioned within the cylinder chamber such that the piston and cylinder share a central longitudinal axis. The piston and cylinder each comprise respective sidewalls, the respective sidewalls defining a lateral space between the piston and the cylinder. The lateral space and a piston conduit have the capacity to permit the fluid to move from a first chamber to a second chamber and to permit the fluid to move from the second chamber to the first chamber.
