Abstract: A claw-pole magnetic levitation torque motor includes a stator component and a rotor component. The stator component includes an end cover, upper and lower claw poles, coil skeletons, coils, and a flux guide sleeve. The cavity formed between the upper and lower claw poles accommodates the coil skeletons, on which coils are wound. The rotor component includes a ring-shaped shell, a permanent magnet, a base, and a shaft. The shell is fitted outside the claw poles, the bottom of the shell includes a base having a base platform shoulder, in the center of which a blind hole is opened. The lower end of the shaft is fixedly arranged in the blind hole, and the upper end of the shaft passes through the flux guide sleeve. The stator component is assembled with the rotor component through a gap-fitting between the magnetic guide sleeve and the shaft of the rotor component.

Abstract: A shaft-distributed double-acting roller piston pump includes a front end cover, a pump casing, a rear end cover and a pump core assembly. The pump core assembly includes a guide rail assembly including left and right guide rails arranged back to back. The side surfaces of the left and right guide rails away from each other are space cam curved surfaces. A flow distribution shaft is installed in the center of the guide rail assembly. A cylinder assembly is installed on both sides of the guide rail assembly including left and right cylinders, between which a piston assembly is arranged. The piston assembly forms left and right closed cavities with the left and right cylinders respectively. The piston assembly performs axial reciprocating linear motion under the constraint of the cylinder assembly and the guide rail assembly, and the volumes of the left and right closed cavities change continuously.
