<p>1,211,132. Anti-roll apparatus. ANDRE CITROEN SOC. ANON. 8 Jan., 1968 [19 Jan., 1967], No. 1159/68. Addition to 1,157,016. Heading B7D. A vehicle comprises a fluid operated power steering system and an anti-roll device as specified in Specification 1,157,016, in which the action of the time delay piston 19 is inhibited during cornering in response to a pressure differential in the steering circuit. In one of the lines 43a serving the hydraulic steering ram 44 is incorporated a member 42 having spring controlled one-way valves 47 and 48 which produce a pressure differential, according to the direction of flow, in lines 45 and 46. These act, in conjunction with springs 55 and 56, upon pistons 49 and 50 which act upon a piston 51 in a closed hydraulic circuit with the damping piston 19 so as to oppose its damping effect. In a modification, Fig. 2, the pistons 49<SP>1</SP> and 50<SP>1</SP> are acted upon through orifices 64 and 65 in washers 62 and 63.</p> |
