Abstract (en)
It comprises a valve (4) which connects each bowl with a waste water storage tank (2), said valve (4) comprising a valve housing (21) with a cylindrical cavity (22) and a rotating cylinder (25) housed therein and provided with a transverse through conduit (26) which, when the valve is in the open position, connects inlet (23) and outlet (24) conduits of the valve, the ends of the transverse conduit being adapted so that the rotating cylinder (25) completes the closing of the inlet conduit (23) and of the outlet conduit (24) non-simultaneously. The border of the ends of said transverse conduit (26) and of the inlet (23) and outlet (24) conduits are provided with a cutting edge, so as to produce a scissor effect. The system also comprises floating watertight joints (29) arranged within recesses in the adjacent surfaces of each pair of elements that undergo relative movement, said joints (29) being pressed against said surfaces by means of a pneumatic system when the moving elements (25) are at rest. <IMAGE>
