Abstract

1. Electro-pneumatic device generating timed gas pulses, which is supplied from a source (14) of gas at predetermined pressure, characterised in that it comprises : a pneumatic circuit with three branches comprising respectively a pressure reducing valve (4), a negative-pressure generator (9) and an electrically operated valve (7), for applying respectively to a pneumatic memory cell (8) a pressure, a negative pressure and a gas pressure signal for the control of the cell (8) ; and an electrical circuit comprising a timer (3) and an operatable or movable contact (19) for supplying the electrically operated valve (7) through the agency of a diode bridge (18).
