connected to external vacuum source. A part of the first chamber has an
opening on which a magnetic seal with a plurality of evenly distributed holes
is placed and fitted over this seal on the outside of the monoblock section
first chamber is a deformable strip of magnetic material which is movable from
one position which closes the first chamber to another position which opens
