PURPOSE:To shorten the extent of a hose for fluid recovery by installing a fluid receiver chamber, collecting a fluid being leaked out of a fluid cylinder, on the circumference of this fluid cylinder, and connecting this chamber to a return passage via a drain hose and a throttle part. CONSTITUTION:Each fluid cylinder 3 is set up in space between symmetrical front and rear wheels and a car body 1, and each hydraulic chamber 5g of gas springs 5 is interconnected to each hydraulic chamber 3c of these fluid cylinders 3 via each of interconnecting passages 4. A hydraulic pump 8 is connected to the interconnected passages 4 via a hydraulic pipeline 10, the feed or exhaust of a fluid to or from each fluid cylinder 3 is controlled by each flow control valve 9 installed interposingly in the point midway in the pipeline 10 and thereby a suspension characteristic is variable controlled. In this case, an interconnecting groove 3j leading oil leaked out of a seal member 3i at a specified part is formed on th circumference of a rod guide member 3h of the fluid cylinders 3, and this groove 3j is interconnected with an oil receiver chamber 3k installed on the circumference of a cylinder body 3a. Then, this oil receiver chamber 3k is connected to a return passage at a takeout port 3l. |
