ABSTRACT OF THE DISCLOSURE A fluid-operated vibrator having improved structure for lubricating the bearings of an eccentric portion thereof. A portion of the pressurized fluid delivered to the drive motor of the vibrator is bypassed through the drive shaft of the motor. After lubricating the bearings, the lubricant fluid is returned to the exhaust fluid line. The bypass passage may effectively define a pressure drop restrictor for improved lubrication of the bearings. The inlet and outlet to the motor may be connected to a conduit structure having an outer exhaust conduit and a supply conduit extending longitudinally within the exhaust conduit.
