Abstract

1488990 Pistons MAHLE GmbH 17 Dec 1975 [21 Dec 1974] 51657/75 Heading F2T An annular support 1 for inclusion in the material of a light-alloy piston, to support a piston ring in a groove 3, has cylindrical bores 2 inclined either relative both to the longitudinal axis of the piston and to a plane perpendicular to this axis or positioned in a plane perpendicular to the axis but not intersecting the axis, the bores serving to secure the support 1 in the piston. Adjacent bores may be oppositely inclined. The bores 2 may be cast into the support or bored.
