Principle

The operation of these pneumatic timers is similar to that of

electronic timers (circuit with capacitor/resistor)

Timing by charging of reservoir

The reservoir fills via the flow restrictor until the switching point

of the timer output is reached (positive or negative).

The non-return valve allows the reservoir to be emptied rapidly

for the next timing.
