The water supply line (2) delivers water to a tank which also receives emulsifier, and includes a venturi nozzle at an intermediate point. The tank is divided by a mobile internal membrane (15) to form two chambers, each supplied with water from the supply line at points on either side of the venturi nozzle. The membrane is secured to the tank walls by a ring (32) which traps the edge of the membrane against a wall surface and is secured by screws (33) to the wall. Alternatively, the membrane may be trapped between a pair of guide ribs (35,36) integral with the tank wall and an elastic locking ring (37) of composite material, e.g. glass fibre or shape memory material. |
