ABSTRACT:
An improved closed loop pneumatic system for driving a piston in a cylinder which employs a low pressure tank for receiving exhaust gases, a booster compressor transferring the gases to a high pressure tank which drives the piston on the up stroke. The constant interconnecting of a low pressure tank through a piston pressure equalizing the line improves the efficiency of the actuator. The larger, deep-well system utilizes an improved means for recovering and recirculating lubricating oil within the closed loop. Two species of the invention are described in this application. One primarily designed for deep wells and one designed primarily for shallow wells.
