MOVABLE MACHINE FOR JETTING A LIQUID JET, FOR EXAMPLE PAINT ON A FIXED HORIZONTAL SURFACE FOR FORMING A LINE

摘要

The inventive machine for jetting a liquid paint jet on a fixed horizontal surface on which it moves comprises a liquid paint container (5), at least one spray nozzle (6) and a pump (7) peristaltic with respect to a connection to said liquid paint container (5) and to the spray nozzle (6) by means of a paint supplying circuit (13) provided with remotely control tap (14). Said circuit (13) comprises a pressure regulator (21) which is arranged upstream of the tap (14) and comprises a first feeding output of the spray nozzle (6) and a second output connected to the container (5), wherein said second output delivers a paint flow in the container when the pressure of a paint flow in the regulator (21) is equal or greater than a calibration value. A sealed air-filled volume (23) forming an expansion chamber is connected to the circuit.
