DAMPING FORCE VARIABLE AIR DAMPER FOR GRADUALLY GENERATING DAMPING FORCE ALTHOUGH AIR PRESSURE IS LOW BY USING A DAMPER TO WHICH A SPRING IS APPLIED

摘要

PURPOSE: A damping force variable air damper is provided to reduce the manufacturing cost by simplifying the structure and to absorb external shock by only varying the applied air pressure.;CONSTITUTION: A damping force variable air damper is composed of a first spring(50), a second spring(60), a third spring(70), a rod(46), and a piston(40). The first and second springs are formed on front and rear sides of the piston. The rod is projected through the second spring to buffer load. The third spring is installed between the piston and the second spring. The piston is arranged to be spaced from the second spring by elastic force of the third spring in the state where the action of the pneumatic pressure is removed.;COPYRIGHT KIPO 2010
