An auto-cycling plunger including a hollow, longitudinally extending body and at least one first directional outer seal disposed on an exterior surface of the body for creating a seal between the body and a well bore. A portion of the seal is spread resiliently outwardly from the body with an applied pressure, thereby increasing the degree of sealing. The plunger also includes a valve stem including a valve member. The valve stem extends through the body and has actuable ends extending from the body. The valve stem includes an actuating head external to and proximal a first end of the body, the head being larger than the internal diameter of the first end of the body. The valve stem can be shuttled between an open position and a closed position. In the open position, the valve member is longitudinally spaced from a valve seat on the body to allow fluid flow through the body. In the closed position, the valve member is seated on the valve seat, thereby sealing the body and preventing fluid flow therethrough.
An auto-cycling plunger for use in lifting a fluid out of a well bore, the auto-cycling plunger comprising:
