Title:
GAS SPRING TYPE VIBRATION ISOLATOR AND METHOD OF CONTROLLING THE DEVICE
Document Type and Number:
WIPO Patent Application WO/2007/125663
Kind Code:
A1
Abstract:
A vibration oscillator comprises a spool valve and a pressure differentiator.
In order to improve the dynamic characteristics of the spool valve in the dead
band, the vibration isolator is so controlled that the feedback value of pressure
differential value follows a reference model having such a linearity that the
relation between an input voltage and an output flow passes through a zero point
to compensate the nonlinearity of the spool valve.
