Abstract
A multi-point hydraulic suspension system for a land vehicle has two or more individual hydraulic actuators. These two or more actuators are each operatively arranged between a suspended structure and a wheeled base of the land vehicle for relative positioning one another. A common supply of pressurized fluid has a given pressure and a selectively operable pump with an inlet and an outlet, for increasing the given pressure of the common supply of pressurized fluid. A fluid reservoir is in selective fluid communication with the inlet of the pump. Controllable valve means are interposed between each of the two or more actuators and the common supply of pressurized fluid for selectively bringing each of the two or more actuators into fluid communication with the common supply of pressurized fluid in response to a control unit for controlling the valve means and the pump.
