PURPOSE:To eliminate the necessity for thrust bearing lubricating oil in a device and decrease its cost, by providing an injection nozzle of the tangential injection turning device along the tangential direction in the peripheral part of a rotary unit in a plane crossing at a right angle with the rotary axial line of the rotary unit. CONSTITUTION:A tangential injection turning device provides fluid receiving parts 14, formed as a curved type fluid receiver groove. in a peripheral part 2a of a spacer 2, integrally mounted to a rotary unit 1, further injection nozzles 11 along almost the tangential direction to the peripheral part of the rotary unit in a plane crossing at a right angle with the rotary center axial line of the rotary unit. In this way, the device, including no component in the axial direction of the rotary unit in the component in the injection direction of fluid injected from the nozzle to the fluid receiving part, eliminates the necessity for lubricating oil of a thrust bearing in turning. |
