適用范圍：This International Standard 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. For the cast iron part the recommended material is class 10 ac-cording to ISO 6621-3. For special applications material classes 20 to 50 may be used. Variation in face design and spring groove from these may be used, as recommended by individual manufacturers, in plain or chromed versions. The tangential forces of coil-spring-loaded oil control rings can be varied over a wide range. Explanations and recommenda-tions are given in clause 6. The normal range for axial width of coil-spring-loaded oil con-trol rings (3 to 8 mm inclusive) is divided into 0,5 or 1,0 mm steps. In tables 15 to 20 dimensions are given for coil-spring-loaded oil control rings with an axial width of 4,75 mm (i.e. 3/16 in) for existing applications in inch units. This International Standard applies to coil-spring-loaded oil control rings up to 200 mm inclusive for reciprocating internal combustion engines. It may also be used for piston rings of compressors working under analogous conditions.
