标准范围

规定了DSF-C、DSF-CNP、SSF、GSF、DSF、DSF-NG和SSF-L型螺旋弹簧加载控油环的基本尺寸。螺旋弹簧加载的机油控制环（包括3至8 mm）轴向宽度的正常范围分为0.5或1.0 mm的台阶。适用于往复式内燃机活塞发动机直径小于等于200 mm的螺旋弹簧加载的控油环，也可用于在类似条件下工作的压缩机活塞环。

Specifies the essential dimensions of piston ring types DSF-C, DSF-CNP, SSF, GSF, DSF, DSF-NG and SSF-L coil-spring-loaded oil control rings. The normal range for the axial width of coil-spring-loaded oil control rings (3 to 8 mm inclusive) is divided into 0,5 or 1,0 mm steps. Applies to coil-spring-loaded oil control rings up to and including 200 mm diameter for reciprocating internal combustion piston engines and may also be used for piston rings of compressors working under similar conditions.
