An oleopneumatic suspension for motor vehicles which has, in addition to the usual suspension cylinder, a hydraulic accumulator and damper for each wheel, a regulator valve for each axle which connects additional dampers to a further hydraulic accumulator for each axle. The additional dampers and hydraulic accumulator are brought into play when the valve is open and are rendered inoperative when the valve is closed. The regulator valve may be operated by other vehicle-operating parameters.

An oleopneumatic suspension for a motor vehicle comprising, for each wheel, a cylinder provided with an accumulator and damping means for each axle, an additional oleopneumatic accumulator cooperating with a first additional damper connected to the cylinder of one of the wheels of the axle and with a second additional damper connected to the cylinder of the other wheel of the axle, and means for switching the accumulator and the two additional dampers into or out of circuit, each axle being equipped with a slide valve suspension regulator adapted for switching the accumulator and the two additional dampers of the axle into or out of circuit under the effect of the same hydraulic pressure acting simultaneously against resilient means on the two regulators of the front axle and of the rear axle, wherein the slide valve of the suspension regulator has a T shaped groove establishing a hydraulic connection between the trim corrector and the suspension cylinders when the slide valve of the suspension regulator is in a closed position, said T shaped groove being sufficiently narrow so as not to appreciably influence the flexibility and damping characteristics of the suspension.
