Abstract
A mandrel valve and gas lift valve mechanism that is adapted to be interconnected in a production tubing string within a well in order to produce fluid from the well under conventional gas lift methods. The gas lift valve includes a housing carried by a mandrel. The housing has a ball type valve element disposed in a valve chamber. Within the mandrel there is a linearly moving valve actuating sleeve having a cam which coacts with a stem on the ball valve so that linear movement of the sleeve causes rotation of the ball valve.
