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内、结构回式压缩机,其内型线短幅线的内等距线构成。

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.

根据线的形成原理,以线的内包络线为定内腔曲线,动径实体化后作为,定、按照一定关系运动则形成一种新型线泵。
