  • the deflection end faces and the cover parts are joined together in a watertight and pressure-tight manner. Sealed bridge channels are formed between the cover parts and the deflection end faces, which connect adjacent or mutually associated channel openings.
  • the base body mostly extends longer in the longitudinal dimension than in the width dimension, the length ratio can be reversed in the two dimensions or the lengths can be at least substantially the same.
  • the base body is usually a cuboid structure. It can also be at least partially free of corners and thus round.
