Abstract

1527418 Pistons WELLWORTHY Ltd 27 July 1977 [6 Aug 1976] 32968/76 Heading F2T The thermal expansion of a light metal piston is controlled by a steel sleeve-shaped insert 6 which extends axially along the skirt 2 from below the lowermost groove 5 in the piston wall, a portion 8 of the skirt wall extending inside the sleeve 5 but terminating above the lower edge 6a of the insert 6. The sleeve is said to give satisfactory expansion control of the upper portion of the piston skirt without a severe weight penalty.
