摘要：
A filter device (10) for an internal combustion engine includes a separator that is embodied as a cyclone preseparator (26), a main filter element (36) exchangeably arranged in a housing compartment (68) of the filter housing (12), and a secondary filter element (38. The housing compartment (68) includes insertion stays (64). The main filter element (36) is embodied in as a double bellows filter including a first radially inwardly positioned filter bellows (40) and a second radially outwardly positioned filter bellows (42) surrounding it. Upon closing of a servicing housing cover (18) a sealing force is generated that acts onto the main filter element (36) and is maintained in the closed state of the servicing cover (18).
