Abstract

PURPOSE: To prevent fluctuation of cylinder head and also to accomplish its seal, by fitting stepped rings to seal rings, and fitting these rings around a hollow pipe erected at the central portion on the upper surface of piston.
CONSTITUTION: Coil springs 18, 19 and corrugated expander 15 of a heat-resisting material are fitted on the outside of rings 8, 9, 10, so that these rings are fitted around hollow pipe 5 with uniform contact pressure. In order to allow free movement of rings 8, 9, 10 and to facilitate sealing and assembling, stepped rings 11, 12 are fitted in several stages to the upper wall surface 17 of combustion chamber, and rings 8W10, expander 15 and coil springs 18, 19 are fitted, in combination, to the inner peripheral surface of the recess. With such an arrangement, seal can be accomplished by making the inner diameter to cylinder head 3 several millimeters (L) larger than the outer diameter of stepped rings 11, 12, and fixing the upper cylinder 13 to cylinder head 3 by means of bolts 16 in the manner that stepped rings 11, 12 are moved smoothly.
