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.
A pressure averager (1), especially a flange pressure averager, with a base body (10) and a separating membrane (5) fastened to a side (14) of the base body (10) in a fastening area (6) for the separating membrane (5) that can be loaded from the outside with a pressure, characterized by at least one recess (9) in the base body (10) on the side of at least a part of the fastening area (6) of the separating membrane (5), whereby 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) and/or the separating membrane (5).
The pressure averager according to a previous claim, in which a bottom of the recess (9) is as deep or deeper than a chamber bottom (7′) of a chamber (7) below the separating membrane (5).
The pressure averager according to a previous claim, in which the fastening area (6) for the separating membrane (5) is formed by a web, in particular a narrow web (6′).
A pressure averager (1), especially a flange pressure averager, in particular a pressure averager according to a previous claim, with a base body (10), 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, and with an assembly arrangement (3) that bends the base body (10) during the fastening of the pressure averager (1) to a counterpiece (2) under tension, characterized in that the fastening area (6) for the separating membrane (5) and/or the separating membrane (5) is/are arranged in the area of a tension plane (n) of the base body (10), wherein a distinctly reduced tension occurs in the area of the tension plane (n) and the separating membrane under the bending force in comparison to a tension that would result if the separating membrane (5) were arranged on the surface (14′) of the base body (10).
The pressure averager according to a previous claim with an assembly arrangement (3), especially a flange (12), for fastening the pressure averager (1) to the counterpiece (2) in such a manner that the side (14) of the base body (10) with the separating membrane (5) faces the counterpiece (2), wherein the base body is braced in a concavely bent manner relative to the counterpiece (2) during the assembly by means of the assembly arrangement (3).
