Abstract:
PROBLEM TO BE SOLVED: To provide a device capable of being easily and inexpensively manufactured in place of a sensor device by a publicly known technique and requiring only a small installation space. SOLUTION: The device is equipped with an outer chamber 3 filled with gas and an inner storage chamber 4, and the inner storage chamber 4 is connected with a hydraulic system and filled with hydraulic fluid and the outer chamber 3 is sealed from the inner storage chamber 4 via medium separation elements 6, 7 and equipped with a blocking device 8. In the case that an end position sealing member 9 has a defect, when the inner storage chamber 4 is emptied, the inner storage chamber 4 is completely or at least partially blocked for a connection conduit 5 to the hydraulic system.

Abstract:
PURPOSE:To protect a bladder of a rotating accumulator by a method wherein longitudinal members fixed to the main body of a container are inserted into the bladder. CONSTITUTION:A pre-pressurized gas filled in a gas chamber (a) in a bladder 10 is compressed and liquid is introduced into a liquid chamber (b) from the feeding and discharging port 12, resulting in that the bladder 10 is compressed by the liquid to reduce a sectional area of the bladder. At that time, the part between the longitudinal members 13 and 13 inserted in the bladder is deflected inwardly, so that in case of three longitudinal members 13, the bladder 10 forms a delta shape, and in case of six longitudinal members 13, the bladder 10 forms six petals to hold the longitudinal members 13, resulting in that even if the main body 8 of the container is rotated, a rotating movement of the main body 7 of the container is transmitted from the fitting 15 to the longitudinal members 13 and the bladder 10 to cause the bladder 10 to be rotated along with the main body of the container, so that the bladder 10 is not twisted and so the bladder 10 is not damaged at all.
