Self-adjusting downhole sucker rod pump spacing tool

A self-adjusting downhole sucker rod pump spacing tool comprising:

• a cylinder, a piston, a piston rod, and a valve assembly, the piston rod comprising first and second ends, the first end being external to the cylinder and configured to be connected to a sucker rod string, the second end being positioned within a sealed cylinder chamber and operatively connected to the piston;
• the cylinder confining fluid within the cylinder chamber, the cylinder chamber comprising a first chamber and a second chamber;
• the piston being coaxially positioned within the cylinder chamber such that the piston shares a central longitudinal axis with the cylinder;
• the piston and cylinder each comprising respective sidewalls, the respective sidewalls defining a lateral space between the piston and the cylinder;
• the valve assembly having the capacity to permit a portion of the fluid to move from the second chamber to the first chamber;
• the cylinder comprising a seal cap though which the piston rod is capable of moving;
• the piston and piston rod each further having the capacity to relocate along the central longitudinal axis of the cylinder;
• whereupon movement of the piston to a first position, a first portion of the fluid moves from the first chamber to the second chamber through the lateral space without passing through the piston;
• whereupon movement of the piston to a second position, a second portion of the fluid moves from the second chamber to the first chamber through the lateral space without passing through the piston, wherein movement of the piston changes the distance between the spacing tool and a sucker rod pump positioned downhole from the spacing tool.
