[0045] See also Figure 3 , the plurality of rollers 10 are arranged along the outer circumference of the rotor 8 .

[0046] See also Figure 3 The eccentric sleeve 9 is eccentrically arranged relative to the rotation line of the output shaft of the motor 5. Due to the eccentricity of the eccentric sleeve 9, the volumes of the rollers 10 at different positions in the relative eccentric direction are also different. Through this volume difference, with the corresponding distribution plate 6, the function of oil suction and discharge can be achieved.

[0047] See also Figure 3 A circuit control board 14 is installed inside the controller housing 2, and the circuit control board 14 is electrically connected to the motor 5 through a wire, and the intermittent and continuous operation of the motor is controlled by the connection of the control signal line.

[0048] See also Figure 4 The electric pump upper cover 3 is provided with a positive power terminal 15, a negative power terminal 16 and a signal terminal 17, and all three are electrically connected to the circuit control board 14 through wires, and the signal terminal 17 is located between the positive power terminal 15 and the negative power terminal 16.

[0049] See also Figure 3 The rotor 8 is sleeved on the output shaft end of the motor 5 through a graphite sleeve 18 .

[0050] See also Figure 3 A pressure limiting valve 19 is installed in the oil inlet port 11 to maintain the stability of the delivery process.

[0051] Working principle: The electronic pump is mainly composed of a motor 5, a pump body composed of a rotor 8, an eccentric sleeve 9 and a roller 10, and a distribution plate 6. The eccentric sleeve 9 in the pump body and the output shaft of the motor 5 are eccentric relative to the rotation line. When the pressure cylinder is subjected to external pressure, the roller 10 begins to move outward, thereby reducing the volume between the roller 10 and the injection nozzle, so that the liquid is compressed and flows out. Subsequently, the pressure cylinder is affected by the reduction of external pressure, and the roller 10 begins to move inward, thereby increasing the volume between the roller 10 and the injection nozzle, so that the liquid is sucked in. Through this volume difference, the entire operation process, coupled with the corresponding distribution plate 6, can achieve the function of sucking and discharging oil. When this process is repeated continuously, the fuel electronic pump can realize continuous delivery of liquid. There is a control unit in the controller housing, and the control program of the multifunctional electronic pump in the control unit solves the practicality of the single-function electric pump that cannot meet the diesel filter supply and exhaust functions that need to be adjusted, and the problem of not being able to adjust the working time of the electric pump to control the degassing and fuel-saving functions to adapt to the vehicle.
