<p><P>PROBLEM TO BE SOLVED: To provide an air spring supporting structure for supporting a supported body from underneath with a simple structure. <P>SOLUTION: In stead of a conventional air spring supporting structure, the air spring supporting structure includes a master valve which brings a P port and A port into a cut-off sate when pressure is applied to the pilot port to maintain the P port and A port in a communicated state, a main piping system which communicates between the pressure source and air spring through the master valve, a balance valve which brings the P port and a B port opened to the air into the communicated state when inner pressure of the air spring is higher than the pressure applied to the A port and which brings the P port and A port into the communicated state when the inner pressure of the air spring is lower than the pressure applied to the A port, a line which communicates the P port of the balance valve and the pilot port of the master valve and a line which leads the set pressure to the A port of the balance valve. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
