A damper apparatus (10) is disclosed for damping movement between a first (12) and a second element (14). The apparatus includes an elongate housing (16) secured to the first element, the housing having a first (18) and a second end (20). The housing (16) defines a bore (22) which extends between the ends of the housing (16). A rotor (24) is connected to the second element (14), the rotor including a first (26) and a second portion (28). The first portion (26) of the rotor (24) is rotatably disposed within the bore (22) of the housing. A biasing device (30) has a first (32) and a second termination (34), the biasing device (30) extending between the second portion (28) of the rotor (24) and the housing (16) for rotationally biasing the rotor (24) relative to the housing (16). A seal (38) is disposed between the first and second portions of the rotor. The seal (38) cooperates with the bore (22) for sealing the bore relative to the second portion of the rotor such that in use of the apparatus, damping fluid (40) sealed within the bore (22) by the seal (38) dampens rotational movement of the rotor (24) relative to the bore when the rotor is rotationally biased. The arrangement is such that movement between the first (12) and second elements (14) is dampened. <IMAGE> |
