<p>Sanitary toilets, of the type having direct draining and rinsing without flushing or syphoning effect, constituted by a bowl (1) of truncated-pyramid overall shape comprising, at the level of its small base in the lower position, a flap (14) controlled by a pneumatic actuator (15) for intermittent communication with a draining conduit, and the bowl comprises at least one nozzle (9) for projecting rinsing and draining water coming from a pressurising chamber, and the installation is characterised in that it is connected to an energy source constituted by a source of compressed air communicating, on the one hand, with a pressurising chamber in order to provide the high-pressure feed of the nozzles (9, 9') for rinsing and for draining and, on the other hand, with the pneumatic actuator (15) for manoeuvering the flap (14), this communicating operation being carried out by a pneumatic-register directional control valve capable of regulating and controlling the draining cycle which comprises the synchronised phases, in the first place, of opening the flap and projecting pressurised water and, in the second place, of closing-off and stopping the projection of water. <IMAGE></p> |
