    Abstract: PURPOSE:To prevent misassembling of springs, lack of spring or piston parts and interference of the spring with the piston by fixing springs to the piston fittedly enclosing an accumulator chamber. CONSTITUTION:In forming a piston 4, convex parts 4c and 4d of small diameter are provided on the both sides of a division wall 4a of the piston 4. Respective one end of the first compression coil spring 5a and the second compression coil spring 5b are formed into spiral spring parts 5c and 5d, each of whose center parts has a diameter allowing the convex part 4c or 4d to be inserted, and the first compression coil spring 5a and the second compression coil spring 5b are fitted to the convex parts 4c and 4d on the division wall 4a of the piston 4 by swaging and caulking the ends of convex parts 4c and 4d after the center parts of the spiral spring parts 5c and 5d have been inserted into the convex parts 4c and 4d of the division wall 4a.

    Abstract: PURPOSE:To prevent the entry of compressed gas from a gas chamber into a fluid chamber by providing between a cylinder and a piston a pressure fluid chamber filled with pressure fluid which surrounds the piston. CONSTITUTION:Between two T-rings 18 surrounding a piston 6, a ring groove 22 is made, and a pressure fluid chamber 24 is formed between the ring groove 22 and the inside surface of a cylinder section 15. Moreover, a small piston 26 is air and fluid tightly fixed in the closed-end round hole made on the gas chamber 16 side of the piston 6, and the closed-end hole internal space is connected to the pressure fluid chamber 24 by use of a through-hole 28 and it is filled with oil. And the small piston 26 is pressed not only with the gas in the gas chamber 16 but also with the force of a spring 32, and therefore the fluid pressure in the pressure fluid chamber 24 is higher than the gas pressure in the gas chamber 16, reversing the pressure gradient; thus the leakage of gas can be prevented.

    Abstract: PURPOSE:To ensure the safe of an accumulator by mounting a mechanism, which serves to detect the current position of a moving piston constituting the wall face of a pressure accumulator chamber, on a piston rod. CONSTITUTION:A permanent magnet piece 15 and a reed switch 16 which serve to detect the current position of a moving piston 2 constituting the wall face of a pressure accumulator chamber 3 are mounted on a piston rod 6. When a adjusting mechanism for the internal capacity of the pressure accumulator chamber 3 fails to operate properly, the failure can be detected electrically by the permanent magnet piece 15 and the reed switch 16. The safe characteristics can be ensured.

    Abstract: PURPOSE:To permit usage of a piston having the longitudinal length of a cylindrical wall on the side including a partition wall and a flange member adjustable so as define a piston stroke width corresponding to the engine characteristics by cutting the cylindrical wall on the side previously set longer and not including the partition wall and the flange member. CONSTITUTION:A piston has a cylindrical wall 1, a partition wall 2 for separating the inside of the cylindrical wall 1 and a flange member 3 for attaching a sealing ring on the outer periphery of the cylindrical wall 1. Coil springs are disposed in the upper and lower portions in the cylindrical wall 1 separated by the partition wall 2 to form a double spring type piston. In this construction, the cylindrical wall 1 has a cutting portion 1a previously set longer in the longitudinal direction at either end opposite to the side including the partition wall 2 and the flange member 3. The cutting portions 1a at both ends not including the partition wall 2 and the flange member 3 are cut so as to define a piston stroke width of an accumulator corresponding to the characteristics of an engine employed.
