A single handle mixing tap includes a tap body within which is a valve mechanism comprising a pair of discs, one of which is rotatable against the other and also movable transversely across the other, whereby fluids to be mixed together from two separate inlets communicating with aligned apertures through the discs can have the ratio of their volumes, as well as their combined volume, varied. The movable disc is coupled by a ball joint arrangement to a rotatable and tiltable handle, whereby the axis of rotation of the disc and the handle through the ball joint during rotation of the disc, and the axis of tilting of the handle relative to the disc at the ball joint during transverse movement of the disc, is such that substantially all forces applied by the handle to the ball joint are radially of said joint rather than along the longitudinal axis of the tap thus relieving friction between the faces of the discs and lowering the operating forces to thereby reduce possible damage to the discs. The tap body is closed by a cap having an opening through which the handle extends. The size and shaping of the handle, the size of the opening and the axis of tilting of the handle are such that during all tilted positions of the handle, it substantially closes the opening. Controls are also provided to limit the degree of rotation of the movable disc, to limit the tilting of the handle, and to provided adjustable control for the upper and lower temperature limits of the fluid mixture issuing from the tap.

A single handle mixing tap having a longitudial axis, said tap comprising: a tap body; a rotatable and pivotable handle; and a valve mechanism in the tap body, said valve mechanism comprising; a pair of discs each having at least one aperture, a movable one of the pair of discs being rotatable and transversely movable relative to a fixed one of the pair of discs whereby fluids to be mixed from two separate inlets to the tap in communication with the apertures can be mixed when said apertures are at least partially aligned, each of said at least one aperture being partially to substantially aligned to thereby very a ratio of volumes of each of the fluids as well as a combined volume of the fluids, and a ball joint arrangement coupled to the handle through a lever, said lever being rotatable and pivotable with rotation and pivoting of said handle, said ball joint arrangement comprises a ball received within a complementary socket in the lever, said ball having at least one pin engaging a slot within said socket, said at least one pin extending transversely of the longitudinal axis of the tap, rotation and pivoting of the handle being transferred to the movable disc through said lever, said handle and lever being rotatable about an axis of said ball joint to transversely move said movable disc, the axis for rotation and axis for pivoting being positioned such that substantially all forces applied by the handle to the ball joint are radially of said joint rather than along the longitudinal axis of the tap.
