Abstract

The liquid distributor has a continuously rotating circular plate (1). The plate (1) carries on its periphery a number of pressure rollers (2). The rollers (2) press against supple tubes (5) containing the liquid to be distributed. The distributor has also two jaws (3, 4) connected by a clip (8). The jaws (3, 4) are mounted so as to pivot on two diametrically opposed axes (6, 7) and to press the tubes (5) against the rollers (2). At least one of the fixing points (9) of the jaws (3, 4) connecting clip (8) is mounted so that it can be adjusted on one jaw. The length of the connecting clip (8) is itself not altered. The clip (8) carries at one of its ends a hook (12) which connects into a catch fixed to one of the jaws. The other end of the clip forming the pivoting axis is mounted on a support platke (9). The support plate has at least an oblong slot (10) in it which cooperates with a bolt (11) fixed on the other jaw.
