Method for controlling a header valve on a snorkel of a submarine

摘要

The variation of water level (8) of the snorkel (6) is measured, and a water level course is calculated in advance from the measured values. The poppet valve (12) arranged at the snorkel of a submarine (2) is controlled at least on the basis of the prediction of water level. The detection time of the water level is repeated continuously, and the prediction of the water level is updated on the basis of an increase in the measured values. An independent claim is included for a device for controlling a poppet valve arranged at the snorkel of a submarine.
