UNDERCUT STATOR FOR A POSITIVE DISPLACEMENT MOTOR

A Moineau style stator includes a stator tube having a plurality of rigid helical lobes formed on an inner surface thereof. The helical lobes define a major internal tube diameter that is greater than a pass through diameter of the tube such that the major diameter undercuts the pass through diamete...
