Abstract (en)
[origin: EP0109303A2] Apparatus for and method of spraying a substance such as paint onto a road surface or the like to form a coating of uniform thickness in which the speed of the vehicle (10) mounting the system is detected and a speed signal produced which controls air flow through a variable flow air valve (34) to a diaphragm air pump (50) which supplies paint or other substance to a spray gun (22, 24). The speed is detected by a road wheel (40) which feeds a train of pulses to a frequency to D.C. converter (39). The converter (39) produces an electrical signal which controls a transducer (44) for controlling the variable air valve (34).
