Plastic fuel filter

摘要

The filter grid (8) has first (12) and second (13) layers of intersecting parallel ribs. The layers occupy adjacent planes. At crossing points, the layers are bonded. Plastic fuel filter comprises grids of parallel ribs produced e.g. as concentric cylinders and bonded together at intersections, having being produced in a single injection molded process, complete with all required fittings and seals. Independent claims are included for the injection mold used, and for the corresponding method of manufacture.
