<p>A fluid suspension unit, particularly for heavy motor vehicles, comprising an outer cylinder and an inner cylinder slidably mounted within the outer cylinder, the outer and inner cylinders defining therein a chamber of variable volume containing hydraulic fluid and compressed gas. A diaphragm divides the chamber into two portions and has an opening therein which is normally closed by a mushroom valve to open when the compression of the fluid suspension unit under the action of the load applied thereto reaches a predetermined level to allow part of the compressed gas contained in said chamber below said diaphragm to be displaced into the upper portion of said chamber containing compressed air only at elevated pressure.</p> |
