A coherence device for a piston ring and a cylinder is provided to minimize leakage of blow-by gas by abrasion of a piston ring and prevent engine oil from flowing into a combustor. A coherence device for a piston ring and a cylinder includes a piston ring groove(52), a piston ring(70), and a slider(80). The piston ring groove is connected to an oil pathway(51) to be supplied an oil. One end of the piston ring is inserted into the piston ring groove and the other end of the piston ring is in contact with an inner wall of the piston(60). The slider is movably installed at both insides of the piston ring groove so as to be in contact with one end of the piston ring. A piston(50) of the coherence device for the piston ring and the cylinder has a piston hole(53) coupled with a connecting rod(C). The piston is coupled with the connecting rod by a piston pin(P). |
