Sectional fluid-cooled piston for I.C.- engine - has head accommodating piston rings connected by central screw arrangement to piston shaft

摘要

The ignition forces introduced from the head (1) into the shaft via inner support ring surfaces (5) are supported inside the shaft via a hollow conical support ring (7) widening to the shaft end on to the nave of the shaft (2). Radially inside the hollow conical support ring is a collar (8) uncoupled from the ignition force support assembly for support of the expansion screw (3). The collar has the shape of a hollow cone widening to the head of the expansion screw. Between the head of the expansion screw and the collar is introduced a socket (4). USE/ADVANTAGE - To improve the durability of the fluid-cooled piston for an internal combustion engine.
