<p>PURPOSE:To precisely and surely detect gas leak of an accumulator by providing a detector to detect difference of material property of gas and liquid in a gas chamber. CONSTITUTION:A float switch device 21 providing therein with a float 23 and an opening/closing contact point 24 operatively associated with displacement of the float is mounted on the side of an accumulator 1, and the contact point 24 is connected with an alarm device 26 through a sealed terminal 25. Hereby, when a piston 3 moves to the gas chamber 5 side by gas leak, or, when liquid in a liquid chamber 4 leaks to the gas chamber side, gas in one part of the gas chamber 5 is substituted by liquid and this is detected with the float switch device 21. Consequently, gas leak of the accumulator 1 can be detected precisely and surely.</p> |
