Preferably the passages 22 are radial and a spindle 3 is secured onto the body 1 by means that allow slight axial travel, and is non- rotatably fixed relative to the internal body 2 such that the spindle 3 is capable of adopting any one of a plurality of positions by means of rotating in said body 1. Preferably the spindle 3 is urged away from the body 2 by a compression spring and includes a stud 31 which may be selectively engaged in recesses 14 in a slot 13 in the body 1. <IMAGE></p> |
