Method of determining gas pressure in vehicle hydro=pneumatic suspension

摘要

A change in distance between wheel and chassis results in fluid being returned to the reservoir. The volume of fluid is proportional to the gas pressure. The connector (18) fits in the filler opening (2) of the reservoir (1). The manually-controlled valve (26) is closed. The return line (22) is disconnected from its pipe (8) and connected to the container input (20). The vehicle is jacked up on one side and the volume of returned fluid measured on the scale (34).
