Filter for Fluids and an Additive Container for a Filter

摘要

A filter (10) for liquid has a filter housing (14) with at least one hollow filter element (12). The filter element at least partially surrounded by a liquid guidance region (54). At least one additive chamber (50) of an additive dispensing device (38) is disposed on the side of the liquid guidance region (54) opposite the corresponding exterior side of the hollow filter element (12) by means of at least one partition (42). The at least one partition has at least one dispensing port (52) by means of which the at least one additive chamber (50) can be fluidically connected to the liquid guidance region (54). The at least one dispensing port (52) is closed with at least one closure element (58) at least in the original condition of the additive dispensing device (38), this closure element being dissolvable by the liquid to be treated to release the at least one first dispensing port (52) during operation of the filter (10).

1. A filter for a liquid for an internal combustion engine, comprising:
a filter housing (14) including
a chamber enclosed within the filter housing;at least one inlet (24) for receiving liquid to be treated; andat least one outlet (22) for treated liquid; at least one round hollow filter element (12) arranged within the chamber of the filter housing (14) and separating the at leas one inlet from the at least one outlet; at least one liquid guidance region (54) at least partially surrounding the filter element within the chamber; an additive dispensing device (38) operable for dispensing at least one additive, the additive dispensing device (38) having
at least one additive chamber (50) for at least one additive; wherein the at least one additive chamber (50) of the additive dispensing device (38) is disposed at least partially on the side of the liquid guidance region (54) opposite a corresponding exterior side of the hollow filter element (12) and is separated from the liquid guidance region (54) by means of at least one partition (42); wherein the at least one partition has a dispensing port (52) by means of which the at least one additive chamber (50) can be connected fluidically to the liquid guidance region (54); wherein the at least one dispensing port (52) is closed by at least one closure element (58), at least in the original condition of the additive dispensing device (38), this closure element being dissolvable by the liquid to be treated to release the at least one dispensing port (52) during operation of the filter (10).
