Filter apparatus with pivotable filter cartridge

A filter apparatus for use with a hydraulic machine, the filter apparatus comprising:

• a connecting part comprising (i) a sealing face configured for sealing abutment on the hydraulic machine, and (ii) a pivoting appendage extending along a pivot axis on a side of the connecting part facing away from the sealing face;
• a filter cartridge;
• an input connector arranged within the sealing face;
• an output connector arranged within the sealing face;
• a first fluid flow path leading from the input connector to the output connector;
• and
• a separate retaining part on which the filter cartridge is fixedly received, the retaining part fluid-tightly adapted to the pivoting appendage such that (i) a pivoting position of the pivoting appendage with respect to the pivot axis is continuously adjustable relative to the connecting part, and (ii) between the retaining part and the pivoting appendage, a first pressure chamber and a second pressure chamber are arranged,
• wherein the first fluid flow path leads from the input connector through the connecting part by way of the first pressure chamber through the retaining part to the filter cartridge, further through the retaining part to the second pressure chamber, and further to the output connector by way of the connecting part.
