PURPOSE:To perform car height increase quickly and decease slowly by forming part of a working liquid supply/exhaust passage from a plurality of passages in parallel to one another, and by equipping one of these passages with a check valve and the other with a throttle. CONSTITUTION:The working liquid sucked up by a pump 21 from a reserver tank 22 diverges at a divergent valve 24 on a common passage 23 into two passages for front and rear wheels, 25R, 25L, and further sent via respective divergent valves 27, 31 into an independent front wheels passage 28(FR, FL) and another for rear wheels 28(RR, RL). Thereby the working liquid is supplied and exhausted to/from a cylinder liquid chamber 17 through an external piping 6, to provide elongation/contraction of cylinder unit 2. Here the two independent passages 28 are equipped with respective flow control valves 29 in the same construction. Each flow control valve 29 is composed of No.1 passage 28a with a check valve 38 and No.2 passage 28b with a throttle 40 and an opening/closing valve 40 in series, wherein the two passages 28a, 28b are arranged in parallel with each other. |
