发明名称 Scroll vacuum pump
摘要 The scroll pump has the capability of preserving a minimal play between the joints disposed on the ridges of each of the spiraling walls and the flat wall facing it. Such an arrangement, possible owing to the slight difference in pressure prevailing between two adjacent transfer chambers, makes it possible to prevent wear and tear on the joints, soiling of the transfer chambers as well as overheating due to friction on the joints.
