<p>The branches of the channels for feeding the cleaning fluids, formed in the dispensing bar (1), continue to fork (B1, B2, B3, B4, B5, B6, B7, B8, B9, B10, B11, B12, B13, B14, B15), optionally finally splitting into three-way branches (T1, T2, T3, T4, T5, T6, T7, T8), until each dispensing hole (10) is fed by its own channel, so that the flow of fluids is distributed essentially in equal amounts and at the same pressure between the various dispensing holes (10) in the bar. The cleaning liquids are fed by respective reciprocating positive displacement pumps (63, 163) which are activated by pneumatic actuators (65, 165) having a piston which is suitably larger than the piston (64, 164) of the said pumps and being activated by the stream of air produced by the same source and at the same pressure as that conveyed to the dispensing bar, mixed together with the liquids dispensed by the pumps, in order to convey and atomize the said liquids. This ensures that the delivery pressure of the cleaning liquids is always correlated to and greater than the pressure of the stream of air, even when the latter is subject to variations in pressure. <IMAGE> <IMAGE></p> |
