1. A filter for hydraulic fluids for hydraulic circuits, the filter comprising:
a container exhibiting inside at least one housing compartment fluidically communicating with at least one inlet and at least one outlet associated with said container, at least one filtering cartridge engageable with the container inside the housing compartment, the filtering cartridge partitioning the housing compartment in a first chamber fluidically communicating with the inlet and a second chamber fluidically communicating with the outlet, the filtering cartridge being configured and positioned for determining the filtering of the hydraulic fluid from the inlet and passing from the first to the second chambers,the container exhibiting at least one engagement portion projecting inside the housing compartment and defining at least one collar having an outer coupling lateral surface,the filtering cartridge exhibiting a respective engagement portion defining a respective collar exhibiting an inner coupling lateral surface configured for tightly engaging outside the outer coupling surface of the container;the outer coupling surface of the engagement portion of the container exhibiting, along a cross-section, a polygonal shape, the inner coupling surface of the engagement portion of the cartridge being at least partially countershaped to the outer coupling surface of the container, said outer and inner coupling surfaces being configured for cooperating with each other to define a removable engagement between the filtering cartridge and the container. |
