Document Type and Number:
Japanese Patent JP2674706
Kind Code:
B2
Abstract:
A tap for liquids comprises a cylindrical hollow body in which are a liquid inlet and a liquid outlet. A fixed disk comprising a single opening for liquid to pass through is disposed in the tap body between the liquid inlet and outlet. A rotary disk comprising a single opening is disposed in contact with the fixed disk, between the latter and the liquid outlet. The rotary disk is rotated relative to the fixed disk by an operating rod between a closed configuration in which each disk closes off the opening in the other disk and an open configuration in which the openings in the disks are at least partially superposed. The opening in the fixed disk has an elongate shape which widens gradually from a relatively narrow first end to a relatively wide second end which is angularly offset relative to the first end by more than 180 DEG . The second end is delimited externally by a circular arc concentric with the disk. It is delimited internally by an approximately radial straight line segment defining with the circular arc an angular sector open towards the first end of the opening.
