Under the thread (6) is situated a seal with a sifter (3) and at least one inlet duct (11), built in a body member (1) or an embedded whirling peg (21). An inlet duct (11) is equipped with whirling member for bringing the water into a whirling chamber (13), and a body member (1) is equipped with connecting member movably linked to the hollow tubular housing (2) with a bottom wall and a accommodating connecting member for switching between standard and economical mode. A bottom wall of the hollow tubular housing (2) is equipped with at least one central outlet opening (16) situated under a whirling chamber (13), while a diameter of a central outlet opening (16) for exit of water in the economical mode is 0,1 to 3,0 mm, and at least one peripheral outlet opening (17) for exit of water in the standard mode. Between bottom surface of the body member (1) and inner surface of the bottom wall of the housing (2) is placed an annular separating wall (10, 5 or 22) for separation and sealing of the area of a whirling chamber (13) and at least one central outlet opening (16) from the area of peripheral outlet openings (17), at the economical mode..</p> |
