Abstract

A reciprocating fluid motor, notably for operating a pump comprising an enclosure divided into two pressure chambers by a movable wall, said movable wall experiencing a forward stroke and a return stroke and being resiliently urged towards the return position, a control device responsive to the position of the movable wall controlling a distributing valve to alternately communicate one of said pressure chambers with a high pressure equalling the pressure residing at all times in the other chamber, and with a lower pressure. In this motor the control device and the distributing valve are mounted within the thickness of the movable wall, and the control device is a fluidic flip-flop. If air is selected as energizing fluid for the motor, the high and low pressures can be the atmospheric pressure and the vacuum created in the intake manifold of an engine respectively.
