Abstract: The invention relates to a plastics pipeline comprising at least one pipeline end (1) and at least one support ring (2). It was the underlying object of the invention to improve a plastics pipeline of the type described at the outset in such a way that the support sleeve or the support ring (2) remains firmly connected to the pipeline even in the event of the plastics pipeline being stored in the presence of high air humidity and temperature. This object is achieved by virtue of the fact that the blow molded pipe section (1) runs through the support ring (2) and, as viewed radially, is pressed from the inside outward against the support ring (2), wherein the pipe section (1) engages around the support ring (2), such that the support ring (2), with its outer surface, and the pipe section (1), with its outer surface, are substantially in alignment.

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 coupling fitting comprises a pipeline and a connector sleeve.

Abstract: Coupling element (1) with tolerance compensation for flexibly connecting two elements for guiding media, having two components (2, 3), which can be connected captively to each other in a fluid-guiding manner, wherein a translational, rotational or cardanically tilting movement of the first component (2) against the second component (3) is possible. The invention therefore addressed the problem of improving a tolerance-compensating coupling element (1) of the kind described at the outset in such a way that materials with high strength but low elasticity demands can be used. This problem is solved by the fact that the captive connection (7, 8) has a slotted snap ring (8) that engages through an opening (6) of the first component (2) and behind a bead (7) of the second component (3), thereby preventing the two components (2, 3) from being completely pulled apart.

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.

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.
