ATOS plunger pump is a new type of high-efficiency pump with relatively high technological content. With the continuous acceleration of localization, radial plunger pump will inevitably become an important component of plunger pump application field; For specific details, please refer to the radial piston pump encyclopedia. The following explanation will only take the axial piston pump as an example.
Axial piston pump operates by utilizing the volume change generated by the reciprocating motion of a plunger parallel to the transmission shaft in the plunger hole. Due to the fact that both the plunger and plunger hole are circular parts, high precision fitting can be achieved during processing, resulting in high volumetric efficiency, smooth operation, good flow uniformity, low noise, and high working pressure. However, they are sensitive to hydraulic oil pollution, have complex structures, and are expensive.
The pump oil mechanism of ATOS plunger pump includes two sets of precision fittings: plunger+plunger sleeve to form plunger and barrel assembly (Figure 5-11), and delivery valve and delivery valve seat to form delivery valve assembly.
The plunger and plunger sleeve of the ATOS plunger pump are a pair of precision parts that cannot be interchanged after pairing and grinding. They require high precision, smoothness, and good wear resistance, with a radial clearance of 0.002-0.003mm.
The plunger head of the ATOS plunger pump has a slanted groove on the cylindrical surface, which is connected to the top through radial and axial holes, with the purpose of changing the circulating oil supply; The plunger sleeve is equipped with inlet and return oil holes, both of which are connected to the low-pressure oil chamber in the pump upper body. After the plunger sleeve is inserted into the pump upper body, it should be positioned with positioning screws.
The position of the inclined groove at the plunger head of the ATOS plunger pump is different, and the method of changing the fuel supply is also different.
The oil outlet valve and the oil outlet valve seat are also a pair of precision fittings, which cannot be interchanged after pairing and grinding, with a fitting clearance of 0.01mm.
The oil outlet valve is a one-way valve. Under the action of spring pressure, the conical surface of the upper part of the valve fits tightly with the valve seat. Its function is to isolate the high-pressure oil pipe from the upper cavity of the plunger when the supply is stopped, preventing the oil in the high-pressure oil pipe from flowing back into the fuel injection pump.
The lower part of the oil outlet valve has a cross section, which can guide and pass diesel. There is a small cylindrical surface under the conical surface of the oil outlet valve, called a pressure reducing ring. Its function is to quickly reduce the oil pressure in the high-pressure oil pipe at the end of the oil supply, avoiding oil dripping at the nozzle. When the annular ring falls into the valve seat, the volume above quickly increases, the pressure rapidly decreases, and the spraying stops quickly.

ATOS plunger pumps generally adopt the form of cylinder rotation and end face flow distribution. There is a friction pair consisting of a bimetallic plate and a steel oil distribution plate embedded on the end face of the cylinder body, and most of them use a flat flow distribution method, so maintenance is relatively convenient. The oil distribution plate is one of the key components of an axial piston pump. When the pump is working, on the one hand, the high-pressure oil in the working chamber pushes the cylinder body towards the oil distribution plate, and on the other hand, the oil film pressure between the oil distribution plate and the cylinder body forms a hydraulic thrust on the cylinder body, causing it to deviate from the oil distribution plate. The hydraulic clamping force Fn of the cylinder body to the oil distribution plate is slightly greater than the hydraulic thrust Ff of the oil distribution plate to the cylinder body, that is, Fn/Ff=1.05-1.1, which enables the pump to work normally and maintain a high volumetric efficiency.
Working principle of ATOS piston pump in Italy:
The ATOS Atos piston pump from Italy is an important device in hydraulic systems. It relies on the reciprocating motion of the plunger in the cylinder body to change the volume of the sealed working chamber to achieve oil suction and pressure. Piston pumps have the advantages of high rated pressure, compact structure, high efficiency, and convenient flow regulation. They are widely used in high-pressure, high flow, and flow regulation applications, such as hydraulic presses, engineering machinery, and ships.
The Italian ATOS Atos plunger pump is a type of reciprocating pump, belonging to the volumetric pump. Its plunger is driven by the eccentric rotation of the pump shaft, reciprocating motion, and its suction and discharge valves are both one-way valves. When the plunger is pulled out, the pressure inside the working chamber decreases and the outlet valve closes. When the pressure is lower than the inlet pressure, the inlet valve opens and liquid enters; When the plunger is pushed inward, the working chamber pressure increases, the inlet valve closes, and when it is higher than the outlet pressure, the outlet valve opens and the liquid is discharged. When the transmission shaft drives the cylinder body to rotate, the inclined plate pulls out or pushes back the plunger from the cylinder body, completing the oil suction and discharge process. The oil in the working chamber composed of the plunger and cylinder bore is connected to the suction and discharge chambers of the pump through the oil distribution plate. The variable mechanism is used to change the inclination angle of the inclined plate, and the displacement of the pump can be changed by adjusting the inclination angle of the inclined plate.
