外周縁４ａに沿つた形状に構成する。 What is shown in the figure is a circular arc cc on both sides with a radius r R that is slightly larger than the radius r of the circular arc a on the inner peripheral surface of both ends of the cylinder 1, starting from the center of the line connecting the center points of both circular arcs r R. Draw a perpendicular line perpendicular to the perpendicular line and connect it with an arc dd having a radius Q longer than the line segment drawn with the point of the perpendicular line as the center.
The outer peripheral edge 4a of the piston ring 4
The total outer circumferential length of the cylinder 1 is set to be substantially the same length as the inner circumference of the cylinder 1 due to gap absorption by the abutment 5. The inner peripheral edge 4b of the piston ring 4 is configured to follow the outer peripheral edge 4a.

It will be in a state of pressure contact.

る。 In this way, according to the present invention, the cylinder 1 and the piston 2 are configured to have an oval cross section A, and the piston ring 4 applied to the piston 2 is
is on the bisector of the straight line connecting the arc c along the arc a with a radius slightly larger than the radius of the arc a inside the cylinder 1, and the centers of the arcs c and c, and its center point is A pair of split rings are formed by a circular arc d along the outer periphery of the straight line b with a radius larger than that between the rings, and the abutments 5, 5 of the split rings are connected to pins 6, 6 provided on the piston 2. Since the piston rings 4 are in contact with each other, the piston rings 4
contacts with stress not only the arcs a and a on both sides of the inner peripheral surface of the cylinder 1, but also the straight lines b and b in the tangential direction of the arc a, and thereby the piston ring The outer circumferential surfaces of 4 are pressed together almost uniformly, which has the effect of reliably preventing leakage of explosive pressure.
