Abstract

L'invention concerne un amortisseur hydraulique. L'amortisseur décrit comprend un cylindre divisé par un piston en deux chambres opposées reliées entre elles par au moins un passage d'écoulement. Chacun de ces passages comporte au moins une valve de régulation proportionnelle actionnée par inertie. De préférence, au moins un des passages comprend aussi un orifice doseur servant à régler le débit du passage. Application : suspension des véhicules.The invention relates to a hydraulic shock absorber. The described shock absorber comprises a cylinder divided by a piston into two opposing chambers interconnected by at least one flow passage. Each of these passages has at least one proportional control valve actuated by inertia. Preferably, at least one of the passages also comprises a metering orifice serving to adjust the flow rate of the passage. Application: vehicle suspension.
