Patent FR-2548322-A1 (FR)
Title: Structure with a double sealing ring for a piston
IPC: F16J9/16
Filed: 1983-06-30
Abstract: The invention relates to a structure with a double sealing ring, comprising an upper ring 1 and a lower ring 2 which are mounted coaxially in one single groove 15 of a piston, in abutment against one another; the lower ring 2 is provided with an axial projection 8 which engages in the slot of the upper ring 1 so as to prevent a rotation of the slots of the rings towards one another; the upper ring 1 is partially hollowed out in its slot so as to receive the axial projection 8 so that the projection does not completely pass through the upper ring which can thus close completely on itself about the projection. Application to internal combustion engines, gas engines, and gas compressors.
