<p>The device has an annular body (1) completely covering a pipe (6), where inner diameter (9) of the body is greater than outer diameter of the pipe. A circumferential groove (5) is formed in the body to conduct fluid from an aperture (8) in the pipe. The groove is located between two groove spaces (11), which comprise an O-ring (2) for pressure- and fluid-tight sealing of the groove against the pipe. The groove and the spaces are opened towards the pipe. Another aperture is formed in the body for a nozzle (7) or a branching pipe. The latter aperture is in fluid communication with the groove. The annular body is designed as a hollow cylinder.</p> |
