Float valve for accumulating water in a lavatory flush tank

摘要

A valve (5) having a valve body (7) connected to a rigid vertical tube (27); a movable shutter (22) for closing the valve (5); and a chamber (31) connected to the tube (27) and containing a float (38) for activating the shutter (22) by means of a mechanism (25). A water level adjusting device (45) has a screw (97) activated manually to adjust both the position of the chamber (31) and the configuration of the mechanism (25); the chamber (31) has a column (44) for guiding the float (38), and the screw (97) engages an internal thread (46) on the column (44); the mechanism (25) has a connecting rod (89) connected by an articulated joint (91) to the float (38); and the articulated joint (91) is moved with respect to the chamber (31) by the screw (97) so that the configuration of the mechanism (25) remains unchanged. <IMAGE> <IMAGE>
