HYDRAULICALLY REGULATED LAVATORY FLUSHING SYSTEM OPERATED UNDER HIGH PRESSURE Russian patent published in 1998 - IPC

FIELD: hygienic equipment. SUBSTANCE: lavatory system has accumulating vessel accommodating cylinder which is separated by piston into upper and lower chambers. Piston is connected with cutoff member closing the outlet hole. Upper chamber of cylinder is connected with NC control valve which communicates it with atmosphere. Water source under pressure is connected with header whose one outlet connecting member is communicated with accumulating vessel, while the other, having flow section larger than that of the first one, is communicated with cylinder upper chamber by means of connecting member whose flow section is larger than that of the second one. EFFECT: simplified design, and higher reliability without increasing of water consumption. 3 cl, 4 dwg
