  • FIG 3 illustrates a detail of a direct flushing device 44, similar to 10 described with reference to FIG 1
  • the axis of the restricted opening 46 is angled relative to the axis of the passageway 48, which results in swirling and increased water turbulence, as well as increased absorption of air as the water exits from the restricted opening 46
  • the flow area restricting means comprises two restricted openings 52, 54 having conical passageways 56 58 which are angularly disposed relative to each other Water exiting the openings 52, 54 exhibits a helical motion which is helpful in increasing air entramment and improving flushing efficiency
  • FIG 5 there is depicted a direct flushing device 10, as described with reference to FIG 1 , connected by piping 60 to, and used in combination with a sewage purification installation 62 serving a multi-family house or a group of houses, for example as described in Patent WO 98/43918
  • a direct flushing device 10 In breaking up the solid waste before it reaches the inlet 64 of the sewage purification installation 62, the flushing device 10, seen above toilet 66, eases the task of the purification installation which can then use processing tanks of smaller size and less energy in effluent pumping
