ABSTRACT:
A pneumatic spring 10 with inner 20 and outer 22 chambers which may be pressurized independently to give variable spring rates which are independent of load carrying capacity of the spring. The chambers 20, 22 are formed by gas-impervious membranes 16, 18 sealably attached to an axially spaced apart retainer 12 and piston 14. The effective diameter of the inner chamber is greater than the outer chamber allowing the spring to exert compressive or extensive force depending upon pressures in the chambers. The spring 10 may be used as a vehicle suspension component.
