Abstract
A cylindrical wall for filtering solid particles in a fluid is disclosed herein, through which a fluid is likely to circulate. This wall includes at least one perforated plate having a finite radius of curvature, and at least one grating element superposed on this perforated plate. The grating element includes a plurality of rigid wires extending in a longitudinal direction and positioned adjacent to one another in order to filter the solid particles, characterized in that the grating element is arranged for the wires to be secured to one another only by means of links between adjacent wires, each link between two adjacent wires occupying only a portion of the length of the wires, and having a thickness less than or equal to the thickness of these wires in proximity to this link.
