Abstract

IMPROVEMENTS IN THE AXIAL EXPANDERS OF THE SEGMENTS FOR PISTONS OF MOTORS, COMPRESSORS, PUMPS AND ANALOG MACHINES, intended to cooperate with at least one flat and thin element, characterized in that said expanders present on their support surface with said flat element separate support areas by intervals, where the ratio between the arc length corresponding to these support zones and the arc length of the intervals is notably greater than unity.
