Title:
RIGIDITY-ADJUSTABLE GAS SPRING
Document Type and Number:
WIPO Patent Application WO/2020/024637
Kind Code:
A1
Abstract:
A rigidity-adjustable gas spring. A volume-variable gas chamber (5) is connected with the gas spring by means of a connection pipe (7) that is connected in series with a throttle valve or a shutdown valve (6); the rigidity of the gas spring is changed by controlling the volume change of the volume-variable gas chamber (5) by means of the power provided by a power source; when it is needed to perform quantitative adjustment on the rigidity of the gas spring, a volumetric metering device is added to the volume-variable gas chamber (5) so as to calculate the effective volume of the volume-variable gas chamber (5); the rigidity of the gas spring is quantitatively calculated and controlled according to the parameters of the gas spring, such as current pressure, initial pressure, and an initial volume.
