Abstract

The proposed solution concerns in particular an engine, with at least two valve devices for controlling bleed air in dependence on an operating state of the engine, the at least two valve devices in each case being adjustable between an open position and a closed position.A flow space is provided for at least one fluid flow occurring in the flow space in dependence on a position of the at least two valve devices. Arranged in the flow space is at least one fluid sensor, by means of which at least one position of at least one of the at least two valve devices can be determined on the basis of the fluid in the flow space.
