Abstract

931,287. Controlling road vehicle height; oleo-pneumatic suspension. SOC. D'ETUDES ET D'APPLICATIONS INDUSTRIELLES COMMERCIALS ET IMMOBILLIERES INTERTECHNIQUE. March 10, 1960 [March 11, 1959], No. 8449/60. Classes 108(2) and (3). A vehicle oleo-pneumatic suspension system, which has an annular chamber 24, located in the or each load carrying damper unit A, surrounding the piston-rod 10 and below the piston 2 each such chamber 24 being in communication with a low pressure oil tank 46 from which a pump 44 returns the oil to the suspension device, is characterized in that the or each chamber 24 communicates with a fluid volume compensating chamber d through a passageway of sufficient cross-section to avoid creation of back pressure on the piston during suspension movements. In the embodiment each annular chamber 24 communicates with compensating chamber d through a port 23, concentric annular chamber 6 and duct 53 each of cross-section approximately one-third or onequarter that of the chamber 24. The oil return pipe 54 to tank 46 is of smaller section. Engine camshaft driven pump 44 sucks oil through restriction 62 and delivers it through pipe 48 with pressure fluctuation damper e, and non- return valve 50, to the head of unit A from which it passes through opposed spring controlled damping valves into the upper cylinder chamber 25 whence it flows through piston height regulating hole 22 in the cylinder wall back to the tank 46. Hole 22 will pass the whole output of pump 44 and is preferably the same size as restriction 62 which limits the pump output at high pressure engine speeds. The volume compensating chamber d has a volume of four times the combined volume of the chambers 24 and contains a flexible diaphragm 58 to allow oil to flow in and out freely. In alternatives the hole 22 is connected directly with the oil tank or the chamber 24 extends directly into a tank or chamber bounded by a resilient diaphragm concentric with the cylinder.
