摘要: Disclosed is a displacement pump especially suited for use in very small well bores. The includes piston working cylinder, driven by rotating cam shaft having closed loop cams effecting reciprocation of the piston. carries spool valves positive control liquid flow into and out pumping chambers. Also disclosed transmission mechanism suitable reducing speed an electric motor power source to level driving shaft. diameter high motor, on which mounted mechanism, turn mechanism. An electrical conduit runs through motor.
