Abstract
A valve arrangement for regulating damping pressure on a piston in a vehicle suspension comprises two identical valves in series between opposite sides of the piston. The valves are moved in unison in response to an intermediate pressure between them and by a servo pressure regulated by a further valve which is responsive to the intermediate pressure and to a current signal supplied to a torque motor. The arrangement is a closed system in which damping force is proportional to torque motor current.
