The variable displacement rotor pump achieves adjustable output by regulating the eccentricity angle between the internal rotor and the floating outer rotor through pressure feedback, thereby changing the phase matching relationship between the rotor pair and the oil distribution plate. Compared to variable displacement vane pumps, variable displacement rotor pumps have fewer components, better assembly processes, less wear issues, and higher reliability.

The adjustment mechanism of variable displacement rotor pumps typically controls the center position of the slider through complex profile meshing. Determining and calculating the parameters of the adjustment mechanism profile are complex tasks that require many rounds of iteration for a satisfactory design, making the process intricate and time-consuming.

APT's design software integrates multiple proprietary technologies. With the initial technical requirements, it automatically completes the parametric design of the adjustment mechanism. This includes the precise design of components such as internal and external rotors, adjusting rings, chambers, springs, etc. The process is entirely visualized and parameterized. The software allows dynamic simulation and real-time analysis of clearances, performance, leakage, and other parameters under different pressures and in various states and positions of components, providing great convenience in the design process.

The software supports various types of slider adjustment approaches, such as tooth-enge adjustment and guide groove adjustment. According to pressure control methods, it provides single stage variable, double stage variable and continuous variable, etc. Please refer to the images above for various types, which have already been maturely applied in the automotive field. APT can also customize product features and software functions according to specific customer requirements or technical needs.
