Air spring system

An air spring system comprising:

• an air spring including a mount, a roll-off piston and a flexible member connected between said mount and said roll-off piston whereby said flexible member rolls on said roll-off piston as said air spring expands and compresses during the operation thereof;
• said flexible member delimiting a first volume and said roll-off piston delimiting a second volume and said first and second volumes conjointly defining a common spring volume of said air spring;
• said roll-off piston having an opening formed therein between said first and second volumes;
• a shock absorber mounted completely within said air spring and extending between said first and second volumes through said opening;
• a tapered funnel-shaped insert at least partially surrounding said shock absorber to conjointly define an inner funnel-shaped narrow passage therewith interconnecting said first and second volumes along a first path;
• said insert having a peripheral edge structure defining an interface between said first and second volumes;
• and,
• a plurality of apertures formed in said peripheral edge structure and interconnecting said first and second volumes along a second path whereby air is circulated through said first and second volumes and along said first path and said shock absorber and said second path as said air spring expands and compresses.
