Document Type and Number:
WIPO Patent Application WO/2015/050241
Kind Code:
A1
Abstract:
A hydraulic shock-absorbing device is provided with an extension-side passage and a pressure-side passage interconnecting an extension-side chamber and a pressure-side chamber, an extension-side valve body for opening and closing the extension-side passage, a pressure-side valve body for opening and closing the pressure-side passage, an extension-side rear pressure chamber for biasing the extension-side valve body, a pressure-side rear pressure chamber for biasing the pressure-side valve body, a communication channel interconnected with the extension-side rear pressure chamber via an extension-side resistance element and communicated with the pressure-side rear pressure chamber via a pressure-side resistance element, an extension-side pressure inlet passage interconnecting the extension-side chamber and the pressure-side rear pressure chamber, a pressure-side pressure inlet passage interconnecting the pressure-side chamber and the extension-side rear pressure chamber, a regulating passage connected to the communication channel, and an electromagnetic pressure control valve that is provided to the regulating passage and that controls pressure upstream of the regulating passage, an extension-side load that biases the extension-side valve body by means of the pressure of the extension-side rear pressure chamber being greater than a pressure-side load that biases the pressure-side valve body by means of the pressure of the pressure-side rear pressure chamber.
