| 摘要 |
The present invention refers to a filter (1) for hydraulic fluids for hydraulic circuits comprising: a container (2) defining inside at least one housing compartment (3) fluidically communicating with at least one inlet (4) and at least one outlet (5) associated to said container (2), a filtering cartridge (6) engageable with the container (2) inside the housing compartment (3) and partitioning said compartment in a first chamber (3a) fluidically communicating with the inlet (4) and a second chamber (3b) fluidically communicating with the outlet (5). The cartridge (6) is configured and positioned for determining the filtering of the hydraulic fluid from the inlet (4) which flows from the first to the second chambers (3a, 3b). The container (2) exhibits at least one engagement portion (7) projecting inside the housing compartment and defining at least one collar (7a) having an outer coupling lateral surface (8), while the filtering cartridge (6) exhibits a respective engagement portion (9) defining a respective collar (9a) exhibiting an inner coupling lateral surface (10) configured for tightly engaging outside the outer coupling surface (8) of the container (2). The coupling surface (8) of the engagement portion (7) of the container (2) exhibits a polygonal cross-section; the inner coupling surface (10) of the engagement portion (9) of the cartridge (6) is at least partially countershaped to the coupling surface (8) of the container (2). |
