Abstract
A system is provided for maintaining the position of a valve in a compressor. The valve includes a valve body connected to a piston in a cylinder by a shaft. The valve body is positioned in the discharge outlet of the compressor based on the location of the piston in the cylinder. The system maintains the position of the valve body in response to a movement of the piston by permitting fluid to flow from a fluid source through the piston and into a chamber of the cylinder to urge the piston back to its initial position in the cylinder.
