Title: SURFACE TREATMENT MACHINE WITH FLOW-RATE CONTROL
Abstract:
A surface treatment machine (10), comprising a frame (11) configured to translate with respect to a surface (12) to treat, a surface treatment element (13) connected to said frame (11) and configured to treat with liquid a surface (12), a reservoir (14) connected to the frame (11) arranged to provide liquid to the surface treatment element (13) through a delivery mouth (15); an adjustment element (16) arranged to feed adjustably the liquid supplied from the reservoir (14) to the delivery mouth (15). It is then provided a sensor (20) configured to measure the flow-rate of the liquid from said reservoir (14) towards the delivery mouth (15). A control unit (30) receives from the sensor (20) a signal proportional to the flow-rate for adjusting the adjustment element (16) responsive to this value, in order to deliver the liquid with optimization of the flow- rate. It is possible then to maximize the range of the machine, and to optimize the working time of the operator.
