| 摘要 |
<p>The present invention concerns a security system (1) for a pneumatic accumulator (20), said high pressure gas pneumatic accumulator (20) being connectable with a pump and with a pneumatic apparatus by means of, respectively, a first (51) and second (52) connecting duct, said system (1) being characterized in that it comprises a pneumatic bladder (40) for containing high pressure gas, flow distribution means (30) connected with said first (51) and second (52) connecting duct to said pneumatic accumulator (20) and said pneumatic bladder (40), said flow distribution means (30) being able to pass, through a command, from a first operating position, in which said flow distribution means (30) connect said first (51) and second (52) connecting duct with said pneumatic accumulator (20), to a second operating position, in which said flow distribution means (30) connect first (51) and second (52) connecting duct with said pneumatic bladder (40), so as to inflate said pneumatic bladder (40) with gas and to functionally replace said pneumatic accumulator (20). The present invention concerns even a pneumatic plant.</p> |
