Machine operating according to the Moineau-Principle for the use in deep drilling
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.
摘要（中）：

Moineau机器具有外部管状构件和安装在外部管状构件中的内部管状构件，由此内部管状构件可在外部管状构件的轴向方向上移动，但是可相对于外部管状构件轴向固定在期望位置。 内管状构件具有内表面。 内弹性体内衬固定连接到内表面。 内部管状构件的壁厚小于外部管状构件。 内部管状构件具有相对的端部，其中相对的端部中的至少一个相对于外部管状构件的内壁被密封。
