PURPOSE: To obtain an improoved vibrator utilizing compressed air. CONSTITUTION: There exists an annular space surrounded by a top plate 12, a bottom plate 26, a shaft 24, and a body 18 at the part of a vibrator shaft 24, and a fluid passage is formed between the space and an inlet hole 36 being communicated with a compressed fluid source (or a compressed air source). Air comes in the inlet hole 36, and advances upward through a passage 38. A number of openings 40 are made along the passage 38, and a stream of air is directed therefrom to blades 42 being reciprocated in grooves 54. The blades run to direct a stream of air toward an inside roller indicated by 44 to rotate this. The inside roller 44 is in contact with an outside roller 46 to rotate the outside roller 46. By an eccentric rotation with respect to the blade plates 42 and vibrator shaft 24 with the inside roller 44 and outside roller 46, a vibrator energy is transmitted outward via the vibrator body 18. |
