Abstract
A seal arrangement (40) between relatively movable components (42,48) includes at least one magnet (54) on a first component (48) and at least one magnet (56) on the second component (42). A clearance (55) is defined between the at least one magnet (54) on the first component (48) and the at least one magnet (56) on the second component (42). Springs (58) bias the at least one magnet (54) on the first component (48) and the at least one magnet (56) on the second component (42) towards each other. The at least one magnet (54) on the first component (42) and the at least one magnet (56) on the second component (42) are arranged to repel each other against the spring (58) to control the clearance (55).
