Abstract

The vibrator has an outer case (1) which ends at a pointed tip. At the back of the case is a flexible pipe (27) for compressed air entry and an exhaust (34). An eccentric rotor (5) is held at either end by its central shaft being housed in solid cylindrical collars (2, 3). The rotor has a series of six longitudinal holes through it, while the collars have seven longitudinal holes. Compressed air goes down a central bore in the rotor (30) to a space (32) and then back to exhaust via the longitudinal holes. The number and arrangement of the holes turns the rotor eccentrically.
