Abstract

1,125,031. Piston rings. E. R. R. GREIFENSTEIN. 29 Dec., 1966 [27 Jan., 1966; 18 March, 1966], No. 58075/66. Heading F2T. A radially-acting ex pander for a pistonring or rings 3, 4, 5, 6, Fig. 1, comprises a band 8 and a spring 10 arranged inside the band in a state of compression,. The band may be provided with corrugations 15 and the rings expanded axially by a spring 7. The band itself may be used as a piston-ring, Fig. 14, the spring being retained by lugs 58 while the flangeportions 59 are urged against the walls of the piston-ring groove by lugs 60. In Fig. 13 (not shown), the band is built up of sections (50) along its length, radially-extending portions (52) serving to urge the piston-rings (53) axially while heel portions (55) transmit the radial thrust of the spring (10). In Fig. 10 (not shown), the spring is of non-circular crosssection and urges a band (31) against an oilscraping ring (29).
