Abstract

The present invention relates to an axial piston pump (1) of the rotating inclined plate type for pumping a liquid comprising: a head (25), a plurality of cylinders (30) made in the head (25) in a number greater than two, having axes (C) parallel to each other and the cylinders being arranged radially around a common axis (A) parallel to the axes of the cylinders, a plurality of pistons (75), each slidingly inserted within a respective cyl-inder (30) of the plurality of cylinders (30) for the pumping of the liquid, and a plurality of delivery ducts (145) made in the head (25), each of which runs directly from a re-spective cylinder (30) to a respective delivery valve (120) and is arranged transversely to the axis (C) of the respective cylinder. Where the head (25) has a first side (61) and a second side (62), the second side (62) being opposite to the first side (61) in relation to an imaginary secant plane (S) which contains the common axis (A) and which is paral-lel to the axes (C) of the cylinders (30), where the plurality of cylinders (30) comprises a first arrangement of cylinders, which has its own axis (C) between the first side (61) and the imaginary secant plane (S), and a second arrangement of cylinders, which has its own axis (C) between the second side (62) and the imaginary secant plane (S). Said delivery ducts (145) running from the cylinders (30) of the first arrangement of cylin-ders, run from the respective cylinder (30) towards the first side (61), and the delivery ducts running from the cylinders of the second arrangement of cylinders, run from the respective cylinder (30) towards the second side (62).
