A fuel filter equipped with a quick fastening cover for an internal combustion engine.

摘要

The filter comprises a case (1; 1') for a fuel filter element (2) and a cover (3; 3') that can be built according to two embodiments: with holes (19, 20) allowing the screwing of the filter onto a threaded fix or connection of the fuel supply line, or with elbow-ducts (32, 33) projecting from the cover and integrally formed therewith. Both the cover and the case are of plastic material. The fastening of the cover to the case is obtained by means of a quick screwing and a subsequent blocking thanks to the presence of oblique teeth both in the case (1; 1') and in the cover acting as a ratchet gear arrangement for preventing the unscrewing. A settlement chamber (10) is formed at the bottom of the case (1; 1') having radial projections (5) reinforcing the structure thereof.
