Claims (3)
リング板状をなし、合口を持たずに周方向に連続した合口無しのリング部材と、前記合口無しのリング部材の一面であり、圧縮室に近い側に配置された周方向の一部で半径方向に相互に気密性を有して対向して形成された第2の合口を有するリング部材で、この第2の合口では、対向する部分が周方向に相対的に移動できる第2のリング部材と、
前記第2のリング部材の一面であり、圧縮室により近い側に配置され、周方向の一部で分断されて、周方向に対向する面を有する第3の合口が形成された第3のリング部材を有し、
前記第2の合口と前記第3の合口がリング周方向の異なる位置になるように重ねられることを特徴とする自己潤滑性ピストンリング。 In a piston ring that is overlapped in at least three stages in a groove provided on an outer peripheral surface of a piston that reciprocates between the cylinder and the inside of the cylinder, a specific one of the three stages of the piston ring has no joint. In the position farthest from the compression chamber,
A ring plate-shaped ring member without a joint and continuous in the circumferential direction without a joint, and one surface of the ring member without a joint and a part of the circumferential direction disposed on the side close to the compression chamber A ring member having a second abutment formed so as to face each other with airtightness in the direction, and in this second abutment, a second ring member in which the opposed portions can move relatively in the circumferential direction When,
A third ring, which is one surface of the second ring member, is disposed closer to the compression chamber, is divided at a portion in the circumferential direction, and has a third joint having a surface facing the circumferential direction. Having a member,
The self-lubricating piston ring, wherein the second abutment and the third abutment are overlapped so as to be at different positions in the ring circumferential direction.
その合口に対して直交する合口部分とを備え、しかも、前記第3の合口を持つリング部材は,前記直交する合口部分のみを備える請求項1に記載の自己潤滑性ピストンリング。
The ring member having the second joint is a joint part along the circumferential direction of the ring member;
2. The self-lubricating piston ring according to claim 1, further comprising a joint member orthogonal to the joint, and the ring member having the third joint includes only the joint part orthogonal to the joint.
