Improvements in suspension struts for vehicles.

摘要

A suspension strut of the mono-tube type comprises a cylinder (1) of stepped outline having a portion (2) of greater diameter and a portion (3) of smaller diameter. A volume of gas or air adapted to support at least a part of the load on a wheel of a vehicle is accommodated in the portion (2) of greater diameter, and a piston (8) works in the cylinder (1) against hydraulic fluid in the cylinder (1). The gas or air is separated from the fluid by a floating piston (13), which can be omitted when the portion (2) is disposed at the upper end of the cylinder (1).
