Problems solved by technology

Of course, the discharge channel must be closed when the filter unit is ready for operation, otherwise the clean side and the untreated side of the annular filter element will short-circuit each other and the filter unit will not be able to perform its filtering function

Embodiment Construction

[0025] exist figure 1 , the filter device 1 can be seen from the outside. It comprises a filter housing cover 2 ; the latter forms inside it a receiving chamber 5 in which an annular filter element 6 is arranged such that it separates the untreated side from the clean side. The internal structure is a conventional replacement filter, which is suitable for filtering oil. The middle block 3 is placed on the side of the filter device 1 facing the housing 4 . The housing 4 onto which the filter device 1 is screwed firmly can be, for example, an engine cylinder housing or a cylinder housing. For reasons of simplification, it will only be referred to as housing 4 . The housing 4 is configured such that it includes a threaded dome 15, a ramp 22 adjacent to the dome 15, and an inlet channel 7, an outlet channel 8 and an outlet channel 9 (see Figure 7 with 8 ).

[0026] exist figure 2 In the illustration, the middle block 3 is shown, which is tightly connected with the filter ...

Abstract

The present invention relates to a filter device (1), particularly an oil filter, having a filter housing cover (2) bounding a receiving chamber (5), in which a ring filter element (6) is disposed, having a housing (4) in which a dome (15) is centrally disposed, and onto which the filter housing cover (2) can be threaded, having at least one intermediate piece (3) disposed on the filter housing cover (2) threaded onto the housing (4) between the filter housing cover (2) and the housing, having an inlet channel (7) on the housing side communicating with an unfiltered side of the ring filter element (6) and an outlet channel (8) on the housing side communicating with a clean side of the ring filter element (6), having an idler channel (9) on the housing side, through which the receiving chamber (5) can be emptied when the filter housing cover (2) is removed, having a closure device (11); rotatably disposed about the filter axis (10) comprising a closure element (12) by means of which the idler channel (9) can be closed off.

Description

technical field [0001] The present invention relates to a filter device for liquids, in particular to an oil filter for cleaning lubricating oil used in internal combustion engines of automobiles. Background technique [0002] Filter devices, in particular filter devices for oil filters for automotive internal combustion engines, generally comprise a so-called annular filter element, by means of which the liquid flowing through the filter device is filtered. Periodically, the annular filter element has to be replaced in order to be able to ensure the filtering effect of the filter device. By removing the filter device from the housing, the annular filter element is also removed at the same time. Due to ever-increasing environmental regulations, the replacement of annular filter elements must ensure that no liquid, especially oil, enters the environment. For this purpose, in addition to an inlet duct communicating with the untreated side of the annular filter element and an...
