Abstract
The filter comprises a body (10) defining a chamber (101) to which access is had through an opening (102) closed by a cover (103). The chamber is adapted to receive a filtering cartridge (20). The body (10) is made in two semi-shells (110, 120) which are united in a junction plane (100) extending across the chamber (101), the opening (102) for the passage of the filtering cartridge (20) being astride the junction plane (100). A positioning device (30) for the filtering cartridge is carried by the body (10) to permit the insertion or the removal of the cartridge (20) by a movement in translation in a direction substantially parallel to the junction plane (100) and the positioning and the retraction of the cartridge by a displacement in a direction substantially perpendicular to the junction plane (100). Application in automotive vehicle engines.
