METERING FLUSHING DEVICE FOR VEHICLE TOILET SYSTEMS Russian patent published in 2002 - IPC

FIELD: vehicle sanitary equipment. SUBSTANCE: proposed metering flushing device for toiler systems has liquid metering device connected by pipeline with sprayers located in watercloset bowl, and flushing stopcock. Sprayers are made in form of nozzles 4 with flat outlet end face and rectangular section outlet hole. Number of nozzles is found from equation n = πD/2h where D is diameter of water closer maximum section hole and h is distance between plane in which outlet end faces of nozzles are located and plane of bowl maximum section. Metering device is made in form of pneumohydraulic accumulator 1 with first valve for delivery of liquid along pipeline to nozzles, and second valve for delivery of liquid into pneumohydraulic accumulator. Flushing stopcock is coupled with first and second valves and is made in form of pedal. EFFECT: improved efficiency. 2 cl, 3 dwg
