Abstract
A valve device of a jet engine includes a body, a seat and a flow path between an inlet and an outlet that can be closed and opened. Depending on an actuating force that results from a fluid pressure at a front surface of the body facing the inlet, as well as from a closing force applied to the body, the body can be transferred between open and closed states, and can be transferred into an operational state in which the flow path is opened by a setting device depending on an ambient pressure. The flow path can be opened via the setting device such that a flow cross-section of the flow path corresponds to at least 80% of the flow cross-section of the flow path in the area of the inlet across the entire extension of the flow path between the inlet and the outlet.
