<p>A prime motor with a special-shaped cavity includes a shell (1), an upper cover plate (10) and a lower cover plate (11), wherein the shell (1) is provided with a special-shaped surface inner cavity, an inlet (2) and an outlet (3), and the upper cover plate (10) and the lower cover plate (11) are respectively arranged on each end face of the shell (1). A sealed cavity is formed by the shell (1), the upper cover plate (10) and the lower cover plate (11). A rotor arranged in the sealed cavity includes a rotor body (6), a first combined slide plate (8) and a second combined slide plate (9). The rotor body (6) is a cylinder, and a first guide groove (20) and a second guide groove (21) are decussately arranged in the rotor body (6) in its radial direction. The first combined slide plate (8) and the second combined slide plate (9) are sliding disposed in the first guide groove (20) and the second guide groove (21), and their both ends are attached with the special-shaped surface inner cavity. The height of the special-shaped surface inner cavity is equal to the heights of the first combined slide plate (8), the second combined slide plate (9) and the rotor body (6). The rotor is driven to rotate by the pressure difference between the inlet and the outlet so that the prime motor can output power and the flow rate of the fluid can be calculated by counting the rotation cycle of the rotor.,</p> |
