Definitions
- this controllable valve is the only valve disposed on the exhaust line and involved in the pressure regulation in this line.
- the exhaust line then has no other valve for pressure regulation.
- it may not include any pressure limiting / regulation valve, whether a limiter or a pressure regulator, respectively configured to ensure (especially by mechanical means) that the pressure upstream or downstream respectively of the limiter or respectively the controller remains below a predetermined value.
- the exhaust line could of course include a pressure limiter calibrated to a value such that in normal operation it does not intervene in the regulation of the pressure in the exhaust line).
- the regulation is of the type 'pulse width modulation' (PWM).
- PWM pulse width modulation'
- Such a command can be implemented on an electronic card.
- control can be achieved by controlling - and thus varying - the value of the duty cycle of the valve (ratio of opening time to total time) as a function of time.
- a regulation mode allows a substantially continuous regulation of the flow rate through the valve, and this although the valve is not a continuous control valve.
