ABSTRACT:
A pneumatic-hydraulic pumping device including a jacket member, a cap member mounted at one end of the jacket member and an hydraulic head member mounted at the opposite end of the jacket member. An air head member is mounted in the jacket member intermediate the cap and hydraulic head members to form an air piston chamber between the cap member and the air head member and an hydraulic fluid reservoir space in the jacket between the hydraulic head member and the air head member. An air piston means including a piston head and a piston rod fastened thereto is mounted for reciprocal movement in power stroke and exhaust directions inside the air piston chamber with the piston rod being slidably mounted in the air head member. An air piston return means is mounted in the jacket for moving the piston means in the exhaust stroke direction. The air head member is connected to a source of air pressure by a conduit means. An air valve means is mounted in the air head member for controlling the flow of air into and out of the air piston chamber to thereby control the reciprocal movement of the air piston means. An hydraulic pumping means is mounted in the reservoir space and operatively connected to the air piston means for actuation thereby.
