zero-delivery pressure


zero-delivery pressure
The pressure delivered by a variable-displacement pump when no services are being operated. It is the normal operating mode, with a zero stroke, when no system is being operated.
The swash plate in this case has a positive angle of inclination and is delivering fuel at positive pressure.
The swash plate is at 0° inclination. There is thus zero delivery pressure by the fuel pump.
