Figure 1 is a perspective view of the piston ring joint,
Figures 2 and 3 are cross-sectional views of the abutment portion of the piston ring in Figure 1, with Figure 2 showing the through hole in an open state, and Figure 3 showing the through hole in a closed state. Figure 4 is a diagram showing the relationship between the temperature of the first pressure ring and the amount of leakage from the through hole, Figure 5 is a front view of the piston, and Figure 6 is a piston ring of another embodiment. A sectional view of the abutment portion, and FIG. 7 is a plan view of the abutment portion of a piston ring according to yet another embodiment. 3...First pressure ring, 6...Lower step part, 7...
...Upper step, 8...through hole.
Claims (1)
、合い口の段部のうちいすれか一方の段部だけに
該段部の厚み方向に貫通孔を設け、前記ピストン
リングが高温時には前記貫通孔は他方の段部によ
つて閉鎖され前記ピストンリングが中低温時には
前記貫通孔は開放されるように前記貫通孔の位置
および大きさが決められているピストンリング。 In a piston ring having a stepped abutment, a through hole is provided in only one of the stepped portions of the abutment in the thickness direction of the stepped portion, and when the piston ring is at a high temperature, the through hole is formed in the other step. The position and size of the through hole are determined so that the through hole is closed by the piston ring and is open when the piston ring is at medium to low temperatures.
