Zusammenfassung:	The utility model relates to a totally closed piston ring set. A piston ring (1) consists of a round ring body (2) and an opening (3), wherein the opening (3) is provided with a ring body opening (4); the opening (3) is greater than the ring body opening (4); seams are arranged between the ring body opening (4) and the opening (3) of the ring body (2); all seams face towards the same direction; and an internal opening (5) is arranged in the ring body (2). In comparison with the traditional piston ring, the internal opening is arranged in the ring body of the totally closed piston ring set, an air converging passage is formed in the internal opening, and the whole circulating air sealing is achieved; and by a slider-type sealing interface, the tension force is balanced, the sealing effect is improved, and the service life of the piston ring is prolonged. The totally closed piston ring set is simple in design, easy in production and convenient to use.
