されている。FIG. 1 is a longitudinal cross-sectional view of the above-mentioned conventional accumulator disclosed in Japanese Utility Model Application Publication No. 58-175201. In FIG. 1, 1 is a pressure-resistant accumulator main body, 2 is a supply/discharge path provided at one end of this main body 1, and the supply/discharge path 2 is provided with a valve 2a. 3 is a prada made of an elastic material such as rubber, and 4 is an air supply port valve provided at the other end of the main body 1. When this valve 4 is opened, gas such as nitrogen gas is sealed into the main body 1. By this, the gas filling side and supply/discharge #!
The inside of the main body 1 is isolated from the I2 side by the Prada 3.

定にして流体の脈動を減衰させる。The Prada type accumulator configured as described above is used by being attached to the g-way (not shown) through which fluid passes. The pulsation of the fluid 5 generated by a pump or the like provided in this conduit is propagated into the main body 1 through the supply/discharge path 2. The pulsation of the fluid 5 is a compression wave in which high and low pressures occur alternately, so when the pressure of the fluid 5 is high, the gas sealed in the prada 3 is compressed and the pressure of the fluid 5 decreases, and conversely, the pressure of the fluid 5 is high. When the pressure of the fluid 5 is low, the gas sealed in the prada 3 expands and increases the pressure of the fluid 5, thereby keeping the pressure approximately constant and damping the pulsation of the fluid.

With the above structure, the sealed gas is injected into the Prada 3 from the air supply port valve 4, and the gas is filled in by installing a gas cylinder and an attached air supply hose in the place where the accumulator is installed, and an air supply hose 8 closed. It is a challenge to avoid the hassle of transporting accessory parts such as valves and adapters, which is time-consuming. - The purpose of this invention is to provide a Prada-type accumulator that solves the above-mentioned problems, eliminates the trouble of transporting gas cylinders and their attached parts to the installation location, and facilitates the handling of gas. There is.

る。In FIG. 1, the same reference numerals as in FIG. 2 indicate the same or corresponding parts. In this embodiment, the accumulator main body 1 is composed of a container 1a and a lid 1a which is removably and airtightly fixed to the container 1b by a tightening bolt 6. A large number of rubber-like hollow viscoelastic balls 7 filled with a gas such as nitrogen gas are housed on the opposite side of the Prada 3 from the suction/exhaust passage 2, and the gas-filled side is constituted by cells of the balls 7. Furthermore, an on-off valve 8 is connected and fixed to the tip of the supply/discharge path 2 .
