Abstract (en)
[origin: US4720801A] The paint throughput quantity of a motor-driven throughput control valve of a paint spraygun is set such that first, a sequence of assignments between throughput quantity values and electric valve motor actuation signals is produced and input into a microcomputer as an approximation table. By selecting the desired value of throughput quantity, the microcomputer is then initialized to supply the tabularly-appertaining actuation signal to the valve motor as a control signal and to therefore approximately set the throughput control valve to the desired reference value. Finally, the throughput quantity is continuously measured during paint flow through the throughput valve and the measured values are supplied to the microcomputer as actual values, the microcomputer then supplying regulating signals to the valve motor on the basis of a comparision between the reference values and the actual values and therefore continuously readjusting the throughput control valve to the reference value.
