Damping capacity adjusting mechanism for an air suspension

A damping capacity adjusting mechanism for an air suspension including shock absorber having a piston rod in which is disposed rotatably a control rod for adjusting a damping force, and an air spring having a main air chamber and an auxiliary air chamber, wherein said damping capacity adjusting mechanism comprises:

• a valve body for affording and shutting off communication between said both air chambers to adjust the spring constant of the air spring;
• a support connected to a car body having a rigid member to which said piston rod is connected and in which said valve body is disposed rotatably;
• and
• an actuator provided above said support to rotate said control rod and valve body, wherein said actuator comprises a rotary means, a pair of rods disposed parallel to each other and extended toward said rigid member of said support, one rod being connected to said control rod and the other rod being connected to said valve body respectively, and a means for transmitting the turning force of said rotary means to said pair of rods.
