Spray head

A spray head 1, e.g. for a shower, comprising: an at least partially flexible spray tube 2 having a wall defining a bore for conveying fluid, e.g. water, along the tube and one or more nozzles 4 disposed in the wall to provide a spray pattern. The tube is able to be twisted (i.e. rotated about its axis) to change the spray pattern - e.g. to focus the spray. The tube may be in the shape of a loop, e.g. a circle, and may be made of multiple tube sections 3a, 3b, 3c. There may be a rotary knob 18 with a user handle 20 to actuate the tube rotation. In an embodiment, when a threaded shaft 22 of the knob 18 is screwed into a base 16, the knob presses each of three lever arms 8 against the resilient bias of a respective spring (30; figs.1, 4) causing connecting members 6a-c to rotate relative to receiving portions (11a-c; figs. 1, 4), hence rotating the tube sections relative to a support. Also claimed are a fluid delivery system including the spray head, and a method of varying a spray pattern using the spray head.
