摘要： PROBLEM TO BE SOLVED: To provide a solenoid driven valve capable of maintaining an adequate characteristic as a gas spring without using a pressure sensor for detecting pressure in a pressure chamber. SOLUTION: Two controllers are used to control a gas pressure in a pressure chamber of a valve-closing air spring 20. One is a pressure controller 42 for controlling pressure of compressed air supplied to a supply passageway 26. The other is a pressure controller 43 for controlling pressure of compressed air discharged to an atmosphere from an exhaust passageway 27. Another two controllers are used to control a gas pressure in a pressure chamber of a valve-opening air spring 30. One is a pressure controller 44 for controlling pressure of compressed air supplied to a supply passageway 36. The other is a pressure controller 45 for controlling pressure of compressed air discharged to an atmosphere from an exhaust passageway 37. An air temperature sensor 60 detects the temperature of compressed air in the pressure chambers of the pair of air springs. A pressure control portion 61 controls the pressure controllers 42, 43, 44, 45 based on the temperature detected by the sensor. COPYRIGHT: (C)2003,JPO
