ABSTRACT:
A device for multiplying the effective pulsations on a column of liquid which operates an underground pump. The pulsations are created by a pulse generator at the ground surface and are transmitted through the column of liquid being pumped to operate the underground pump. The pulse multiplier is interposed in the single tube at the ground surface and is effective to partially divert the flow of liquid from the tube to a receiving tank when gas pockets in the column of liquid reach a predetermined degree and relieve the column of the gas pockets by by-passing the liquid under pulsations from the pulse generator back to the receiving tank.
