PROBLEM TO BE SOLVED: To reduce gas volume or filling amount of an accumulator incorporating a displacement sensor. SOLUTION: An inductive displacement sensor to be preferably integrated with the accumulator is proposed to detect a degree of filling of the accumulator. The position sensor has electric windings 10, 11, 12, 13 on a bobbin 9. A winding space not filled with the electric windings on the bobbin is filled with the other windings 17, 18, 19 which are wound on the electric windings 10, 11, 12, 13 and are not connected mutually to reduce gas volume of the accumulator. Preferably, the other windings are made of plastic threads. COPYRIGHT: (C)2003,JPO
