Abstract

PURPOSE:To enable simple detection of a gas sealing pressure, by a method wherein a liquid is forced to a hydraulic circuit after the liquid in an accumulator is discharge thoroughly and a fluid pressure is measured when the liquid starts to flow into the accumulator. CONSTITUTION:A bladder 2 expands, a liquid in a liquid chamber 4 is pressed against the bladder 2 to flow out to a hydraulic circuit 6 at an fluid outlet/inlet 5. When the bladder 2 further expands to contact an inner wall of the accumula tor closely, the liquid in the accumulator is discharged completely while a cush ion cup 12 and a valve body 13 are pressed against the bladder 2A to close the fluid outlet/inlet 5. Then, a pump 9 is driven to force a liquid in a liquid tank 14 to the hydraulic circuit 6 and a liquid pressure is measured with a pressure measuring device 7 when the liquid starts to flow into the accumulator.
