<p>A control valve (300) for an antiroll suspension for a vehicle, the valve having a body (302), sliding valve element (306) which is coupled to a pendulum arm (94) through a linkage (146, 332, 334) so that the valve element slides when the pendulum moves on cornering of the vehicle, the valve including a pressure inlet port (352) between lands (336, 344), a return port (356) and outlet ports (342, 350) which are coupled to hydraulic rams (44) in the vehicle suspension, whereby the valve element operates to control pressure at the outlet ports so as to actuate the rams to thereby reduce body roll on the vehicle. Restricted flow through ducts (340, 348) past pistons (312, 314) and end chambers to ducts (360, 366) and return port (356) provides an increasing pressure differential to generate forces on the valve element (306) which tend to oppose the displacement of the valve element (306) whereby the valve element (306) moves to an equilibrium position which is dependent on the forces transmitted to it from the pendulum arm (94). An antiroll suspension for a vehicle including the valve is also disclosed.</p> |
