Abstract: A housing (110) having a housing body (112), connected to a mating housing cover (114) are arranged along a longitudinal axis (A). The housing (110) receives a filter element (10). A push-twist structure (120) is provided on the housing body and the housing cover connecting the housing body (112) and housing cover (114) by way of a push-twist mount. The push-twist structure (120) having mating push-twist elements (122, 124) arranged on the housing body (112) and the housing cover (114). An anti-rotation lock structure (160) is provided for securing the push-twist structure (120) in its closed position in an anti-rotation lock manner.

Abstract: The present invention belongs to the technical sector of fluid filtration systems which can be used for air filtration in an internal combustion engine. The invention refers to a filtering device (1) including a filtering element (24) which presents an open axial end (26) and an axial end (27) closed by a cover (28); and an intake cover (7). The said cover (28) includes at least a first tubular boss (55) projecting towards the intake cover (7); and the intake cover (7) includes at least a second tubular boss (57) complementary to the first tubular boss (55) and projecting towards the cover (28); the first tubular boss (55) is slotted in the second tubular boss (57). The invention also refers to a tubular filtering element (24) and to a maintenance process of a filtering device.

Abstract: A housing (110), in particular for receiving a filter element (10) for filtering of a fluid, comprising along a longitudinal axis (A) a housing body (112), and a mating housing cover (114). A push-twist structure (120) is provided for connecting the housing body (112) and the housing cover (114) by way of a push-twist mount, the push-twist structure (120) having mating push-twist elements (122, 124) on the housing body (112) and the housing cover (114). An anti-rotation lock structure (160) is provided for securing the push-twist structure (120) in its closed position in an anti-rotation lock manner. The anti-rotation lock structure (160) provides at least one anchor portion (162) arranged along the circumference of the outer one of the housing body (112) and the housing cover (114). A clip element (170) is provided for connecting to the anchor portion (162).
