An injector inlet fuel screen (10) may include a first annular ring (12), a second annular ring (14), and a plurality of support ribs (16-26) extending axially between and connecting the annular rings (12,14). The plurality of support ribs (16-26) may be circumferentially spaced about the annular rings (12,14), and each adjacent pair of support ribs (16-26) and corresponding portions of the annular rings (12,14) may define a filter window (28-38). At least one of the support ribs (16-26) may have a generally rectangular cross-section and at least one of the support ribs (16-26) may have a generally parallelogram-shaped cross-section with no right angles. The fuel screen (10) may further include a plurality of wire mesh panels (40-50), with each wire mesh panel (40-50) overlaying a corresponding one of the filter windows (28-38). The injector inlet fuel screen (10) may be installed on a fuel injector case have four inlet ports, with the screen (10) having six support ribs and defining six filter windows. |
