Abstract
A self-stabilizing gas lift valve apparatus for oil and gas production. The apparatus includes a valve body having at least one gas inlet in communication with an elongated gas chamber in the valve body. An impingement disk is moveable in the elongated gas chamber. A conical plug extends from the impingement disk with the conical plug having a valve plug extending axially therefrom. A conical cup terminates in a valve seat wherein the conical cup receives the conical plug therein. A valve closure force mechanism urges the valve plug toward the valve seat. Gas injected through the gas inlet provides a force upon the impingement disk to overcome the force of the valve closure force mechanism in order to open the valve plug. When the gas injected exceeds a predetermined force, the impingent disk is moved and a conical space between the conical plug and the conical cup is reduced.
