摘要： The present invention relates to a multipurpose viscous damper (100), comprising: an outer cylinder (101); a core rod (102) positioned in the outer cylinder (101); a core piston (103) positioned in the middle and surrounded the core rod (102); a plurality of bypass pipes (104) extending along the outer cylinder (101), each bypass pipe (104) being connected to the outer cylinder (101) adjacent to the two ends of the outer cylinder (101); an orifice controller (105) located on the bypass pipes (104) for providing initial adjustable damping during low to moderate vibration; and characterized by a pair of inner cylinders (106) positioned inside the two ends of the core rod (102); an inner piston (107) positioned in each inner cylinder (106); a fixed sealing (108) located at the two end of each of the inner cylinders (106); and an orifice (109) located at the two ends of the inner cylinder (106) for allowing fluid flowing from the inner cylinder (106) to the outer cylinder (101) during movement of inner piston (107).
