摘要： 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).

摘要： The invention relates to a proportional volumetric doser (10) comprising a motor (20) to which a pump (30) is connected, which pump (30) comprises a tubular sleeve (80) inside which a cylinder (85) is housed in which a small doser piston (62) slides, mechanically connected to an output shaft of the motor (20), wherein an inner surface of the cylinder (85) and the small piston (62) partially define a dosing chamber (48) of an auxiliary fluid to be mixed in the motor (20) in a prefixed amount with the main fluid, where said cylinder (85) has a threaded outer portion that meshes with a threaded portion of a ring nut (70) so that a rotation of the ring nut (70) causes an axial translation of the cylinder (85) and the variation of the volume of the dosing chamber (48), said proportional volumetric doser (30) being characterized in that the sleeve (80) comprises a locking system (100) configured to mechanically lock the cylinder (85) with respect to the tubular sleeve (80) by creating a shape constraint.
