ABSTRACT:
A hydraulically adjustable suspension apparatus for an automobile has a proportional type of solenoid operated valve assembly for controlling the pressure or flow rate of a pressurized fluid introduced into a cylinder tube through a fluid passage. The fluid passage is formed in a piston rod so as to communicate a cylinder tube with a hydraulic control circuit. The solenoid operated valve assembly is integrally attached to either the piston rod or the cylinder tube outside of the cylinder tube.
