<p>PURPOSE:To continuously feed air to the body attitude control device by driving the small oil hydraulic driving air feeding device which can generate high-pressure air continuously and is provided on the car body, and also by feeding pressure oil from the lubricating oil pump, which is already mounted, to the air feeding device. CONSTITUTION:A spool 3 and a pair of pistons 5 are slidably inserted into the body 1 which is divided into a pair of air chambers 11 and a pair of pressure chambers 12. The air chambers 11 are selectively opened into the air suction port and the exhaust port 8, 9. The passage means 21, 23, 24, 25 are made in the spool 3, and a pair of the pressure chambers 12 are selectively connected with the high pressure side pump port 14 and the low pressure side drain ports 15, 16 of the oil hydraulic system. By connecting the pump port 14 to the high pressure oil hydraulic system, a pair of the pressure chambers 12 are alternatively connected with the high pressure side and the low pressure side by the passage means to rciprocatingly move the piston 5 from the air exhaust port 9. Therefore, by feeding pressure oil from the lubricating oil pump which is mounted on the body, air can be continuously supplied to the body attitude controlling device.</p> |
