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