Embodiment Construction

[0055] figure 1 Shown is a filter assembly for fluid flowing within a hydraulic motor or device. The filter assembly 1 comprises a filter body 2 comprising a container 3 and a cover 4 . The filter body 2 delimits a cavity 5 in which the filter assembly 1 comprises a tube 6, which in this embodiment is a central tube. The filter assembly 1 also has a filter cartridge 7 which is shown separately in FIG. 2 .

[0056] The container 3 is equipped with an internal thread 8 and the cap 4 is equipped with an external thread 9 which can be screwed to the internal thread 8 of the container 3 to close the filter assembly 1 . The tight sealing of the filter assembly 1 can also be further ensured by at least one sealing ring 10 inserted between the cap 4 and the container 3 . Thus, when the filter cartridge 7 is damaged, the cover 4 and the container 3 can be easily unscrewed from the filter body 2 to take out the filter cartridge 7 for replacement with a new filter cartridge 7 .

Abstract

The assembly (1) has a removable filter cartridge (7) placed in a filter body (2) and including a cylindrical filter medium (13) with a tubular opening that extends between upper and lower flanges (11, 12). A valve obturating element (20) is secured to one of the flanges to cooperate with a valve seat (15) of the flange. The element occupies closing and opening positions in which the element seals the seat and allows the fluid to pass through the seat, respectively. A return element (21) i.e. spring, which is distinct from the cartridge, returns the element to the closing position.
