The filter has a head (10) with an oil inlet and an oil outlet (11,12), and to which is coupled an open end (21) of a cup (20) lodging a filtering element (30) which has an inner central chamber (32) and an outer annular chamber (33), connected to the oil inlet and oil outlet (11,12). A top cap (50) has a median annular portion (52) affixed to the filtering element (30), and a peripheral portion (53) with windows and positioned on an open end (33a) of the outer annular chamber (33) and seated onto the open end (21) of the cup (20). Rotational locking means (60) and axial locking means (80) are incorporated to the open end (21) of the cup (20) or to the peripheral portion (53) of the top cap (50), it being further provided, in the other of said parts, rotational locking receiving means (70) and axial locking receiving means (90), in which are fitted and retained the rotational locking means (60) and the axial locking means (80). |
