Abstract

PURPOSE:To reduce the attenuation of the oscillation of frequency same as the resonant frequency of a resonator, which is provided in a bypass, in addition to an ordinary valve structure, in an attenuation generating valve unit, by providing a response structure which opens the path by the resonance of the resonator. CONSTITUTION:Inside piston 2, in addition to ordinary valve structure 4a consisting of disk valve 6 and linking path 5, frequency response structure 4b having oscillator 11 elastically supported by springs 9, 10 is provided in chamber 8 placed in the midway of bypass 7. Oscillator 11 is excited by piston 2, which is oscillated by the force corresponding to the attenuation by disk valve, when an oscillation of frequency same as the resonant frequency determined by its mass and the spring constants of springs 9, 10 is transmitted to it, and it opens opening 7a of bypass 7, which has been in closed condition, connects liquid chambers R1, R2 and reduces the attenuation. Consequently, when oscillator 11 is matched with the resonant frequency of the car, ordinary oscillation is suppressed by large attenuation, the attenuation of the oscillation matched with the resonant frequency of the car is reduced, and the resonance of the car is effectively suppressed.
