IPC: F16J15/3232
Filed: 2001-09-27
Abstract: PROBLEM TO BE SOLVED: To share a first lip ring for rotation to the right and a second lip ring for rotation to the left. SOLUTION: Second and third groove parts 111c and 111d crossing a plurality of first groove parts 111b and extending are formed so that angles α and βformed by the concentrically positioned plurality of first groove parts 111b and the plurality of first groove parts 111b are acute angles. Thereby, when a shaft rotates to the right, for example, a refrigerant and lubricant oil flow in the second groove parts 111c into a compressor 100 by a pumping function. When the shaft rotates to an opposite direction, the refrigerant and the lubricant oil flow in the third groove parts 111d into the compressor 100. Thus, the first lip ring 111 for rotation to the right for the compressor and the first lip ring 111 for the rotation to the left for the compressor is shared.  Therefore, the number of the first lip rings 111 for stock is reduced, and product failure caused by wrong assembly is avoided.
