This produces mixts. of different proportions at fuel filling stations. To set all the stages selected by the individual buttons (1), the electric driving motor is controlled only be one starting (9) and one stopping (10) switch. Each of these switches is actuated by selector members (5, 12) common to all stages, by a single button locked in relation to the remainder. |
