Axial piston pump with inclined plate

An axial piston pump of the inclined plate type for pumping liquid comprising:

• a head in which there is at least partially a plurality of cylinders in a number greater than three, with central parallel axes,
• a plurality of pistons that each slide within a respective cylinder of the plurality of cylinders for the pumping of the liquid,
• a suction channel of the liquid to pump, which comprises a primary duct and a plurality of branch ducts, each of said branch ducts being adapted to place the primary duct in fluid communication with a respective cylinder of the plurality of cylinders,
• in which the primary duct is positioned between central axes of the cylinders,
• wherein the branch ducts each comprise:
• a pair of walls, opposing each other and each having a respective curved surface with a single transversal axis of curvature in relation to a plane perpendicular to the central axes of the cylinders, and
• an additional pair of side walls, which are flat and opposed to each other, wherein each of said additional side walls extends from a wall of the pair of walls to the opposite wall of the pair of walls.
