摘要： Methods, apparatus, and improved structure having as their common basis the sequence of collapsing a piston ring in a fixture approximating engine bore diameter, and lapping a locality at the side of the ring while so collapsed, until a circumferentially continuous portion--narrow in width and preferably line size--of the side is flat in the range of at least about 10 to 5 light bands. That is, the out-of-flatness of the circumferentially continuous portion, stated another way, is limited to a maximum range equivalent to about 5 to 10 light bands at standard inspection wavelength. One of the broadest methods here disclosed is the use exclusively of rings so carefully made and so lap inspected as above on a percentage basis that the inner peripheral edge at the side has all points thereon in coplanarity to a degree equivalent to the stated range to seal in absolute contact in a substantially continuous sealing ring.

摘要： Methods, apparatus, and improved structure having as their common basis the sequence of collapsing a piston ring in a fixture approximating engine bore diameter, and separately lapping a major portion of the ring side and a remaining locality -narrow in width, of band size and preferably line size- of the side of the ring while it is so collapsed, until circumferentially continuous portions of the side are flat in the range of at least about ten to five light bands. That is, out-offlatness of the two circumferentially continuous portions, stated another way, is limited in each case to a range equivalent to about five to ten light bands at maximum, at standard inspection wave length. The broadest method disclosed is the use exclusively of rings so carefully made and so lap inspected as above on a percentage basis that the major portion of the side has all points thereon in coplanarity and the remaining locality has all points thereon in coplanarity, all to a degree equivalent to the stated range to seal in respective full face contact and at least full line contact.

摘要： METHODS, APPARATUS, AND IMPROVED STRUCTURE HAVING AS THEIR COMMON BASIS THE SEQUENCE OF COLLAPSING A PISTON RING IN A FIXTURE APPROXIMATING ENGINE BORE DIAMETER, AND LAPPING A LOCALITY AT THE SIDE OF THE RING WHILE SO COLLAPSED, UNTIL A CIRCUMFERENTIALLY CONTINUOUS PORTION-NARROW IN WIDTH AND PREFERABLY LINE SIZE-OF THE SIDE IS FLAT IN THE RNGE OF AT LEAST ABOUT 10 TO 5 LIGHT BANDS. THE BROADEST METHOD DISCLOSED IS THE USE EXCLUSIVELY OF RINGS SO SELECTED THAT THE INNER PERIPHERAL EDGE AT THE SIDE HAS ALL POINTS THEREON IN
COPLANARILITY TO A DEGREE EQUIVALENT TO THE STATED RANGE TO SEAL IN ABSOLUTE LINE CONTACT.
