Abstract
A housing for magnetic particle devices comprising first and second housing members adopted to be assembled in side-by-side axial relation, at least one of said housing members having an annular cavity formed extending inwardly on one side thereof adjacent to the other housing member, an annular tapered surface formed on the side of one of said housing members at an intermediate location radially of the annular cavity and a sidewardly extending annular flange formed on the other housing member for engaging the annular tapered surface to divide the annular cavity into inner and outer cavity portions when the first and second housing members are connected, the annular flange separating the cavity into separate portions on opposite sides thereof, and members connecting the first and second housing members together whereby the annular flange moves axially against and is deformed by engagement with the annular tapered surface to seal between the separate cavity portions. The housing also includes a portion for supporting a rotatable member that extends into the inner cavity portion, the inner cavity portion also containing particles of a magnetizable material.
