ABSTRACT:
The device comprises a motor-rotatable unit which includes a rotary shaft having an eccentric mass and a shaft-enveloping sleeve--which sleeve also has an eccentric mass or eccentric weighted portion. The sleeve, which envelops the shaft, is movable in order to effect juxtaposed, radial alignment of the sleeve mass or weighted portion with the shaft eccentric mass, or a diametrically opposite disposition of the sleeve mass or weighted portion (relative to the shaft eccentric mass), so that the two masses effect an additive unbalance, or, eccentricity, cancel out eccentricity, or produce any in between value of eccentricity. Conduits formed in the shaft admit and discharge pressured fluid to and from the shaft and sleeve interface, to cause selective, rotary movement of the sleeve.
