Water closet low noise pressurised flushing system - has water outlet valve with wire fabric cylinder at centre of opening

摘要

The pressurised flushing arrangement for a water closet has flusher housing with venting opening in the region of its water outlet opening. The arrangement is designed so that air propagated noise level is reduced as well as the noise generated in the body. The air entrainment in water is significantly increased. At the centre of the water outlet opening (19) is arranged a perforated cylinder (13) and flow baffles (15). The latter guides the water flow from outside through the perforated cylinder (13). The latter is made from wire fabric whose mesh size and wire thickness are approx. 0.5mm. The cylinder is approx. 14 mm.
