PURPOSE:To improve comfortableness and ensure maneuver stability by meeting all oscillating conditions and attenuating these effectively without increasing the basic length of a hydraulic buffer device itself and with a simple structure. CONSTITUTION:A base valve 5 is provided with only a check valve 6 for sucking hydraulic oil which opens only in the elongation process of a hydraulic buffer device, and the valve 6 is fixed on the lower bottom of the hydraulic cylinder 1. Moreover, a pressure side damping force generating valve 14 is separated from the base valve 5 and is elasticallysupported to the outer wall side of the hydraulic cylinder 1 so as to slide smoothly to form a floating type which has an accumulator effect and an automatic high/low switching function for pressure side damping force, thus meeting all vibration for effective damping. |
