CA 1337910
A seal for the gap between two relatively rotatable machine parts (1,2) for preventing egress of a liquid through the gap from a space, generally a sealed space for lubricant liquid, connecting to it, at least one of the two facing surfaces in the gap being provided with a helical threaded groove (3) which acts as a liquid thrower cooperatively effective with the other surface to move thrown liquid in the direction of the sealed space (4). There is a superimposed ferrofluid preseal ahead of the threaded section (3) on the side remote from the sealed space (4). The superimposed preseal includes an annular magnet (5) on one part and separated from the opposite part by a narrow magnetic flux gap with a ferrofluid in the gap (6). The flux gap is of radial width equal to the separation of the helical grooved surface from the opposite facing surface.
