形或されて特に問題はないが、その各直状部については
多少とも面圧が不足し勝ちである不都合を伴う。The applicant of the present application has previously developed a device of this type in which a cylinder is constructed into a shape consisting of a pair of outer circular portions with large arcs exceeding semicircles and a straight portion in the middle, and the inner portion of the cylinder is A piston is constructed in a shape substantially similar to this, and a piston ring groove is formed on the outer periphery of the piston to extend along the piston ring, and a piston ring is fitted into the groove. We have proposed a type in which the ring is divided into a circular part that is more than a semicircle, and a pair of straight parts in the middle. Similar to the case of a type piston, there is no particular problem because it is shaped into a self-tension type, but there is a disadvantage that the surface pressure is likely to be insufficient in each straight portion.
即ち各直状部はその両外側の１対の円形部間に存してそ
