Siphon for connection of a pipe to a sewer, to prevent the escape of sewer odors, is free of curves with an odor barrier plate with structured entry and outlet openings

摘要

The siphon (1), at the connection between a pipe and the sewer to prevent the escape of sewer odors, is free of bends with one end (4) for connection to the sewer with a number of holder openings (20,26,29). An odor barrier plate (9) has entry openings (16) concentric around the outlet openings (17). The siphon has two sections (7,8) of different inner cross section dimensions, with the odor barrier plate in the smaller section.
