Other techniques not described are all known to those skilled in the art, and are not described herein again.
The operation principle of the invention is as follows:
as shown in fig. 1, a closed cavity is formed between two adjacent vanes 3, the surface of the ring groove, the inner wall of the casing 1 and the side wall of the ring K1, and there are 18 cavities in total, that is, there are 9 cavities on the left side and 9 cavities on the right side of the ring K1;
taking the right end of the motor as an example, as shown in fig. 1, at the uppermost end, the housing 1 ring K1 is at the leftmost position, where the volume of the chamber is at its maximum. At the lowermost end, where housing 1 ring K1 is at the far right, the volume of the chamber is at its smallest.
All 9 containing cavities are communicated with an oil distribution block 4 on the right side of the motor, some are communicated with a high-pressure cavity through the oil distribution block 4, and some are communicated with a low-pressure cavity through the oil distribution block 4. When a compartment of the motor is at the lowermost end, the volume of the compartment is at a minimum. At this time, the cavity is communicated with the high-pressure cavity through the right oil distribution block 4 and is disconnected with the low-pressure cavity, when high-pressure oil enters the cavity through the oil distribution block 4, torque is generated to push the rotor 2 to rotate, the rotor 2 drives the blade 3 to rotate together, and the slipper 5 rotates around the axis of the ring K1 due to the fact that the slipper 5 is abutted to the side face of the ring K1, and the motor rotates; in the rotating process, the volume of the containing cavity changes periodically, when the rotor 2 rotates from the lowest end to the highest end, the containing cavity is always communicated with the high-pressure cavity, and high-pressure oil continuously enters the containing cavity due to the fact that the volume of the containing cavity is continuously increased, torque is continuously generated, and the motor rotates continuously. The volume is maximized when the chamber is rotated to the uppermost end. At this time, the cavity is disconnected from the high-pressure cavity and communicated with the low-pressure cavity through the oil distribution block 4, and when the cavity rotates continuously, the volume of the cavity is gradually reduced, and oil is discharged to the low-pressure cavity through the oil distribution block 4. When the rotor 4 rotates from the top to the bottom in the cavity, the cavity is always communicated with the low-pressure cavity, and because the volume of the cavity is continuously reduced, oil is continuously discharged to the low-pressure cavity until the cavity returns to the bottom. This completes one cycle. All nine chambers have the same process, so that the motor rotates repeatedly and continuously.
Similarly, at the left end of the motor, the situation is opposite to that at the right end, thereby realizing double action.
If the angle of inclination of the guide block 6 is adjusted, i.e. the angle between the axis of the ring K1 in the housing 1 and the axis of the rotor 2 is adjusted, the rotational speed of the motor can be adjusted.
