Claims

[Scope of utility model registration request]

A composite cylinder 1 consists of a concentric inner and outer cylinder 2.3 with one end open, the open end of the outer cylinder being fixed to a holder 4, a piston 5 inserted into the inner cylinder, and a cylinder surrounding the inner cylinder from the outside. A part of the bottom of the inner cylinder extends in a direction opposite to the open end 8 to form a hole 9 communicating with the outside air. The continuous well hole is closed with a stopper 23 of the cap 10 so as to be adjustable to narrow the gap, and the portion of the piston facing the bottom of the inner cylinder is pressed against the curved surface 11 that widens toward the bottom of the inner cylinder. It consists of an inner end plate 13 and an intermediate disk 14 via an O-ring 12, and a protrusion 15 is provided at the center of the inner end plate so as to rotate in contact with the bottom of the inner cylinder. A protrusion 16 is formed from the disk edge toward the O-ring, and a pair of axially symmetrical protrusions 18 are formed on the base plate 17 of the piston, which the spring presses against, and the protrusions 18 are formed at the corner d of the piston. A slow-reciprocating piston device characterized by being locked in an outer cylinder by.
