Air cushion inverted siphons
The air cushion inverted siphon [[DWAA112:2007]] differs from a conventional one owing to an effective cross section within the inverted siphon (filling height or partial filling level) that is reduced by an air cushion. Thus, the flow velocity can be increased [Hosan1998]. This air cushion is formed by a controlled feed of air into the line. To prevent a discharge of this air, a siphon is placed both in the inlet and outlet area of the inverted siphon.
