<p>PURPOSE:To prevent the deterioration of riding feeling, securing accumulator mounting space and miniaturize an accumulator in the accumulator for hydraulic and pneumatic suspension by fixing an elastic member to the bottom section of a cylinder lower chamber and by elastically urging a free piston. CONSTITUTION:The cylinder lower chamber 20 of an accumulator 15c for gas spring is provided with a spring 22. By this constitution, even if hydraulic pressure in the cylinder lower chamber 20 become lower than the gas pre-charge pressure in a cylinder upper chamber 18, a free piston 16 will not touch the bottom. Therefore, even when the accumulator for gas spring touches the bottom, the deterioration of riding feeling can be prevented and weight reduction and miniaturization can also be realized by simplifying hydraulic circuits.</p> |
