As the sewage passes out of the ejector, its leveltherein reaches the cup C, and continues to lower, leaving thecup full until the weight of liquid therein is sufficient to pulldown the bell, and the spindle, &c, connected therewith, thusreversing the action of the slide valve, and admitting com-pressed air to act on the opposite end of the main valve, drivingit over to the position shown in Fig. 3. This first cuts off thesupply of compressed air to the ejector, and then allows theair within the ejector to exhaust down to atmospheric delivery valve falls on it
