ABSTRACT:
The invention is relative to pressure averagers (1), especially flange pressure averagers, with a base body (10) and a separating membrane (5) that is fastened to a side (14) of the base body (10) in a fastening area (6) for the separating membrane (5) and that can be loaded from the outside with a pressure. At least one recess (9) is advantageously formed in the base body (10) on the side of the fastening area (6) of the separating membrane (5), wherein at least one recess (9) in the base body (10) is dimensioned (t, b) in such a manner that tensions deforming the base body (10) are not transferred or are transferred only in a reduced state onto the fastening area (6). It can also be additionally or alternatively provided that the fastening area (6) for the separating membrane (5) and the separating membrane (5) are arranged in the area of a tension plane (n) of the base body (10) and that an at least reduced tension occurs in the area of the tension plane (n) under the bending tension.
