摘要

1. A single-arm mixer tap for controlling the rate of flow and the mixing ratio of hot and cold water, with a stationary control plate (18) comprising two ducts (19, 28) connected to the hot water supply line (34) and the cold water supply line (34') respectively, a control member (14) movable relative to the control plate (18) being disposed thereon and likewise comprising two ducts (16) and being actuable by a rocker arm (1) pivotable about a shaft (24) and by a rotatable handle (30) provided on the rocker arm (1) by means of a member (10, 11) constructed in the form of an actuating finger, and transmission elements (7), by which the angle of rotation of the handle (30) is converted into a linear movement of the control member (14), the transmission element (7) being interposed between the control member (14) and the inner part (4) of the rotatable handle (30) mounted in the rocker arm (1), the rocking angle of the rocker arm (1) being intended to control a second component of the movement of the control member (14) at right angles to the said linear movement, characterized in that the transmission elements (7) comprise a guide member (9) tiltable about the shaft (24) and simultaneously displaceable along the said shaft (24) (Figs. 1 to 7).
