Abstract: The present invention relates to an axial piston pump (1,1?) with inclined plate for pumping a liquid comprising: a head (20) in which there are at least partially a plurality of cylinders (25) in a number greater than three, with parallel central axes, a plurality of pistons (75), each one sliding inside a respective cylinder (25) of the plurality of cylinders (25) for pumping liquid, a housing seat of a suction valve (115) made in the head (20), a housing seat of a delivery valve (120) made in the head (20). The housing seat of the suction valve (115) and the housing seat of the delivery valve (120) are in direct fluid communication with each other via a rectilinear channel (155) made in the head, said channel in turn being in direct fluid communication with a cylinder (25) of the plurality of cylinders.

Abstract: The present invention concerns an axial piston pump (1, 1?, 1?,1??) for the pumping of a liquid comprising: a head (20) in which there is at least partially made a plurality of cylinders (25) in a number greater than three, with central axes parallel between them, a plurality of pistons (75) each of which slide in a respective cylinder (25) of the plurality of cylinders (25) for the pumping of the liquid, and a suction channel of the liquid to pump, which is equipped with a primary duct (140) and a plurality of branch ducts (145, 145?,145?), each of said branch ducts (145, 145?,145?) being adapted to place the primary duct (140) in fluid communication with a respective cylinder (25) of the plurality of cylinders (25), in which the primary duct (140) is positioned between the central axes of the cylinders (25).

Abstract: This describes an axial piston pump (1, 1?) with inclined plate for pumping a liquid comprising: a head (20) in which there are at least partially made a plurality of cylinders (25a, 25b, 25c, 25d, 25e) in a number greater than three, with central axes parallel to each other, a plurality of pistons (75) each one sliding in a respective cylinder (25a, 25b, 25c, 25d, 25e) of the plurality of cylinders (25a, 25b, 25c, 25d, 25e) for pumping liquid, a plurality of suction valves (115), each one housed in a respective housing seat made in the head (20), a plurality of suction channels (155a, 155b, 155c, 155d, 155e) made in the head, one for each suction valve (115), each of which, independently from the other suction channels, places a housing seat of a suction valve (115) in fluid communication with the corresponding cylinder (25a, 25b, 25c, 25d, 25e), a plurality of delivery valves (120), each one housed in a respective housing seat made in the head (20), a plurality of delivery channels (160a, 160b, 160c, 160d,

Abstract: 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.
