本申请的油分离器的工作原理为：油气混合物通过进气管时，由于管径由大变小，气流速度增大、动能增加，该油气混合物以较大的动能切向进入油分离器，与甩油盘3的离心叶片32发生正交冲撞，产生力偶作用于甩油盘3，使甩油盘3沿着定轴152作高速旋转运动，在此过程中，排气中油滴与离心叶片32、导向曲面发生碰撞、反射、吸附作用，大粒径油滴在离心力作用下直接甩出，沿油分离器内壁落入储油池内，小粒径油滴吸附在离心叶片32、导向曲面上，形成油膜，在吸附力、离心力、重力的作用下，油膜由小变大，由薄变厚，到达锯齿处时，油膜诱导成大油滴，在离心力作用下甩出，沿油分离器内壁落入储油池内。与此同时，油气混合物(含小量油成分)与导向曲面冲撞发生反射抬升作用，在抬升力、压力共同作用下，自下而上流动， 通过第二过滤器4，中等粒经的油滴被分离出来落入下筒体15的下部，油气混合物(含小粒径油成分)继续上升，到达导流圈5时，部分小粒径油滴与导流圈5内壁接触，发生吸附，形成油膜、在重力作用下，油膜变厚成大油滴，落入下筒体15的下部，油气混合物(含部分小粒径油成分)继续上升，上升过程中小粒径油部分聚合成大油滴，在重力作用下落入储油池。冷煤气(含小量小粒径油成分)通过第一过滤器2时，小粒径油滴再次被分离出来，形成大粒径油滴，落入下筒体15的下部。这样含油冷媒气通过油分离器的吸附分离、离心分离、重力分离、多级过滤分离共同作用，将油高效分离出来。
