ダライナ。 From the top spring position when the piston is at the top depth center to the top spring position that is lowered by 1/5 of the stroke, the smaller angle between the piston sliding direction and the groove direction is 45 degrees or more and 90 degrees. The grooves formed on the inner peripheral surface of the cylinder liner intersect as shown below, and for the remaining distance of the stroke, the smaller angle between the sliding direction of the piston and the groove direction is 0 degrees or more and 45 1. A cylinder liner comprising: grooves formed on the inner circumferential surface of the cylinder liner so as to intersect with each other so that the grooves intersect with each other.
