单轴偏心螺杆泵
摘要：
本发明提供一种单轴偏心螺杆泵，其具有：定子32、转子33、外壳体31和引导部件55、56，上述定子32的内周面形成为内螺纹型；上述转子33能够插入上述定子32中，并由外螺纹型的轴体构成；上述外壳体31能够在可压缩上述定子32的第1位置和至少缓和上述定子32的压缩状态的第2位置之间移动；上述引导部件55、56引导外壳体31的端部，并且在允许外壳体31向定子的径向移动的同时，能够限制外壳体31在定子的圆周方向上的移动。
摘要（英）：

A uniaxial eccentric screw pump includes: a stator 32 having a female threaded inner peripheral surface; a rotor 33 configured to be insertable into the stator 32, and formed of a male threaded shaft body; an exterior body 31 configured to be movable between a first position where the exterior body 31 is capable of compressing the stator 32 and a second position where the exterior body 31 at least alleviates a compression state of the stator 32; and guide members 55, 56 configured to restrict a movement of the exterior body 31 in a circumferential direction of the stator while allowing a movement of the exterior body 31 in a radial direction of the stator by guiding an end portion of the exterior body 31.
