The principle of pulse-pause-modulation can be illustrated by looking at the piston displacement curves: at maximum frequency and at reduced frequency.
At maximum frequency, each pulse (marked yellow) is directly followed by a new pulse. At a reduced frequency, exactly the same pulses can be seen, but in between these pulses, a pause is introduced. The duration of this period can be varied. By increasing the pause the number of pulses will be reduced, thus decreasing the flow output of the Chiron. By reducing the pause-period we can increase the frequency and therefore also increase the flow output. In this way the flow-output can be varied between zero and maximum flow output, only by controlling a small electronically operated pilot valve. The result is a very flexible, highly dynamic electronic control of the flow output.
