摘要： The posture of a vehicle is controlled using a specific variable damping force damper without the necessity of changing over the variable damping force damper frequently and at a high rate and without using a vehicle height sensor. A variable damping force damper U having at least two change-over modes including a mode in which the compression side damping force is soft when the extension side damping force is hard and another mode in which the compression side damping force is hard when the extension side damping force is soft is interposed between a vehicle body D and a wheel E. The variable damping force damper U is changed over by means of an acceleration sensor J mounted on the vehicle body D and a controller M including an integrator P for converting a signal from the acceleration sensor J into a velocity signal and a calculation processing circuit Q for outputting a changing over signal to the variable damping force damper U in accordance with the velocity signal from the integrator P.

摘要： In a damping force generator for a hydraulic damper, the valve is protected from pressure rise in the damper and its durability is thereby enhanced. The damping force characteristics can be vary in stepwise fashion by providing a main leaf valve 21 and a sub-leaf valve which closes an opening 21A formed in the main leaf valve 21, and the approximate mid-point of the main leaf valve 21 is supported by a plurality of intermediate seat surfaces 16 from the side of a port 13. The outer circumference of a main leaf valve 64 is supported by an outer circumferential seat surface 62, and the outer circumference of a sub-leaf valve 65 extends outwards to the vicinity of a part where the outer circumference of the main leaf valve 64 and the outer circumferential seat surface 62 overlap.

A passage connects the two operating chambers. A free piston is inserted into a pressure chamber to be free to slide and partitions the pressure chamber into one chamber that communicates with one operating chamber via a one side flow passage and another chamber that communicates with the other operating chamber via another side flow passage. A spring element generates a biasing force for suppressing displacement of the free piston relative to the pressure chamber.

A relief valve is provided in the bypass flow passage.
