Abstract (en)
A flush tank overflow device (2) has a tube (10) extending along an axis (A) and having two open opposite axial ends (12, 13); and a cover (11) at the top end (13) of the tube (10). The top end (13) of the tube (10) has an inlet opening (15) bounded by a substantially annular inlet edge (16); and the cover (11) has a bottom end edge (27), which surrounds the inlet edge (16) and is located radially outwards of the inlet edge (16) and axially below or substantially flush with a top face (21) of the inlet edge (16). The cover (11) and the inlet opening (15) thus form a siphon system (30) which allows to increase the flow rate when the overflow is active.
