DEVICE AND METHOD FOR ADJUSTING RESIDUAL PRESSURE OF BELLOWS

摘要

The invention relates to a device for adjusting residual pressure of bellows, comprising a pneumatic spring device (100, 101) provided with pneumatic bellows (100) used to act as a spring for loads, a valve (103) which is connected pressure-wise to the pneumatic bellows (100) in order to seal or aerate or de-aerate the pneumatic bellows (100); a pressure detection device (102) which is connected pressure-wise to the pneumatic bellows (100) and is used to detect the real pressure in the pneumatic bellows(100); and an electronic controller device used to control the valve (103) according to the difference between a stored setpoint pressure and the real pressure. The invention also relates to a method for adjusting the residual pressure of bellows.
