ROLLER TYPE ORBITING MASS OSCILLATOR WITH LOW FLUID DRAG ABSTRACT OF THE DISCLOSURE A cylindrical rotor is mounted for rotation in a raceway formed in the inside wall of a housing, the outside diameter of the rotor being only slightly less than the inside diameter of the raceway so that the rotor substantially fills the housing. One or more relatively high mass cylindrical rollers is each contained in a cavity or pocket formed in the outer wall of the rotor, each such roller being free to roll within its pocket and to move radially outwardly by virtue of the centrifugal force generated and to roll around in the raceway with the rotor and roller or rollers filling the housing and riding somewhat closely against the housing wall. This effectively fills all of the space in the housing and prevents the formation of a fluid filled "traveling" space in the housing thereby minimizing roller drag due to fluid turbulence.
