ABSTRACT:
Anti-roll system especially for a vehicle, comprising system control means, a tank (4) and a pump (3) for a hydraulic fluid, and two or more stabilizers, each stabilizer comprising an actuator (5, 6) which is arranged to control the relevant stabilizer's moment in dependency of the hydraulic pressure at the actuator's terminals. Each actuator has either one or both of its terminals (A, B) connected to a first terminal (I) of a pressure control module (8) which has a second terminal (II) connected to the tank's inlet side and a third terminal (III) to the pump's outlet side. The control means and each control module are arranged to supply a fluid pressure at its first terminal under control of said control means. The pressure control modules (8) may comprise a series connection of two pressure control valves (1, 2) e.g. pressure relief or limitation valves. As an alternative the pressure control modules (8) comprise a three-way pressure control valve (9), e.g. a three-way pressure reduction valve. To minimize energy consumption of the pump during moderate cornering and straight line driving a pressure control valve is provided in parallel to the three-way pressure control valve.
