A spiraster-type rotary device includes a stator, a rotor and a central sun wheel roller (10). The stator has a cylinder block (1) with a cylindrical cavity. The rotor has a main shaft (3), planetary piston wheel fixed flanges (9) and a planetary piston wheel (8). Two planetary piston wheel fixed flanges (9) are symmetrically fixed on the main shaft (3). The central sun wheel roller (10) is provided between the two planetary piston wheel fixed flanges (9) and sleeved on the main shaft (3). A circular piston space (19) is formed between the outer circular surface of the central sun wheel roller (10) and the cylinder wall of the cylinder block (1). The planetary piston wheel (8) is a column roller wheel. The column roller wheel is mounted in the circular piston space (19) in a rolling manner. Two ends of the column roller wheel are fixed on the planetary piston wheel fixed flanges (9). A spiraster-type fluid motor or engine and a work method thereof and a spiraster-type compressor or pump are also disclosed. The spiraster-type rotary device has simple structure, small volume and light weight. |
