| 摘要 |
The invention relates to a pressure equalization element (1) for equalization of pressure differences between at least two spatial areas assigned to a field device used in automation technology, comprising a main body (2), consisting of a securing element (3) having an axial bore (5), that is used for securing the pressure equalization element (1) in a wall of the field device, and a disc-shaped carrier component (4) having a lateral end surface, wherein the disc-shaped carrier component (4) is provided with a specified number (n, where n >2) of substantially radially running recesses (6) corresponding to the axial bore (5), wherein the radially running recesses (6) are offset from one another by a defined angular offset, and wherein the radially running recesses (6) are provided with a gas-permeable liquid-barrier membrane (8) in the region of the lateral end surface (7) of the disc-shaped carrier components (4). |
