    摘要： A filter assembly for filtering water from an external source, the filter assembly having a manifold assembly and a filter cartridge. The filter cartridge includes a cartridge engagement means while the manifold includes a manifold engagement means. The cartridge engagement means and manifold engagement means cooperatively interfacing for removable attachment of the filter cartridge to the manifold assembly. The cartridge engagement means and manifold engagement means oriented in a retaining relation during removal of the cartridge filter from the manifold assembly such that any entrained pressure within the cartridge filter is vented while the cartridge engagement means and manifold engagement means are in the retaining relation.

    摘要： The invention relates to a liquid filter (1) comprising a filter housing (10), a ring filter insert (2) and a cover (16), the bottom (18) of the housing (10) containing an eccentric outlet (13) for emptying the housing (10) when the filter insert (2) is removed. The filter insert (2) consists of a filter material body (20) surrounded by front panels (21, 22). A blocking element for the outlet (13) is arranged on the front panel (22) facing the bottom (18), and positioning means are provided on the filter insert (2) and on the housing (10), said positioning means bringing the blocking element (24) into engagement with the outlet (13) when the filter insert (2) is inserted into the housing (10). The filter (1) according to the invention is characterised in that the first positioning means is an inclined plane (3) that is embodied or arranged a) on the outer circumference of a filter housing part (15) arranged inside the ring filter insert (2), b) on the inner circumference of the ring filter insert (2), c) on the outer circumference of the ring filter insert (2), or d) on the inner circumference of the filter housing (10); and the second positioning means is a radially protruding nose (4) embodied or arranged, opposite the inclined plane (3), a) on the inner circumference of the ring filter insert (2), b) on the outer circumference of the filter housing part (15) arranged inside the ring filter insert (2), c) on the inner circumference of the filter housing (10), or d) on the outer circumference of the ring filter insert (2). When the ring filter insert (2) is rotated in relation to the filter housing (10), the inclined plane (3) and the nose (4) can be moved in relation to each other in such a way that they slide along each other and bring the blocking element (24) into engagement with the outlet (13).

    摘要： A filter device for filtering oil leakage amounts from hydraulic systems, wherein hydraulic oil can be sucked from a tank (4) via a suction line (10) and leakage oil can be fed via a leakage oil line (12) to the non-filtered side of a leakage oil filter (16). Filtered leakage oil can be fed back from the filtered side (20) of the filter to the tank (4). The invention is characterized in that a valve assembly (26) is provided, by way of which a fluid connection (22, 30) can be released between the filtered side (20) of the leakage oil filter (16) and the suction line (10) in order to reduce the leakage oil pressure in the leakage oil line (12).
