摘要： A Moineau machine has an outer tubular member and an inner tubular member mounted in the outer tubular member whereby the inner tubular member is movable in the axial direction of the outer tubular member but is axially securable in a desired position relative to the outer tubular member. The inner tubular member has an inner surface. An inner elastomer lining is fixedly connected to the inner surface. The inner tubular member has a wall thickness smaller than the outer tubular member. The inner tubular member has opposed ends wherein at least one of the opposed ends is sealed relative to the inner wall of the outer tubular member.
