The new type of rotary compressor has two key parts, an outer rotor and an inner one which employs isometric curve of trochoid as its profile.

从理论上分析了一种新型、外转子结构回转式,其转子型线短幅外摆线的线构成。

According to the formation principle of the tritubercular cycloid in this paper, the rotor, whose bore curve is the inner envelope line of the cycloid, is made with the solid radius vector.

根据三尖摆线的形成原理,以摆线的包络线为定子腔曲线,动径实体化后作为转子,定子、转子按照一定关系运动则形成一种新型摆线泵。
