Abstract: The invention relates to a device for controlling the swirl of a fluid (2) flowing in a pipeline (1). The invention was based on the object of creating a device with which the adaptation of the swirl (2B) of a fluid (2) flowing in a pipeline (1), even in the case of constantly changing initial swirl (2B), to the desired flow conditions in the pipeline (1) is possible. Said object is achieved in that a swirl measuring device (4) and a swirl control device (6) are provided at predetermined positions of the pipeline (1), and the device has an evaluation and encoder unit (5), wherein, in the presence of differences between the measured actual swirl (2B) and the desired swirl, a corrective value can be determined by means of the evaluation and encoder unit (5), and the swirl control device (6) corresponds with the evaluation and encoder unit (5) and, by means of the swirl control device (6), the present swirl (2B) can be adapted to the predetermined desired swirl in accordance with the determined corrective value.

Abstract: The invention relates to a device for controlling the swirl of a fluid (2, 7) flowing in a pipeline (1, 6), comprising a pipeline (1, 6) in which a fluid (2, 7) flows. The invention was based on the object of creating a device with which the adaptation of the swirl of a fluid (2, 7) flowing in a pipeline (1, 6) to the desired flow conditions in the pipeline (1, 6) is possible. Said object is achieved in that the device has at least one predetermined series of flow straighteners (5, 8) and swirl generators (4, 9, 10).

Abstract: A fluid line includes a resonator having an inner part and a blow-molded outer part defining an inner surface. The inner and outer parts are fixedly connected. The inner part is an injection-molded part having first and second radial collars spaced axially apart from each other. The inner part defines a radial circumference with a plurality of orifices formed therein. The inner and outer parts are axially one within the other so that there is no throughflow of secondary air between the first and second radial collars and the inner surface of the outer part. The inner and outer parts have a common end whereat they are airtightly connected to each other. The inner part, the radial collars and the inner surface of the outer part conjointly define two resonant chambers operatively connected to fluid in the fluid line via the orifices.
