EALY弋力叶片泵的工作原理和分类：
叶片泵的结构较齿轮泵复杂，但其工作压力较高，且流量脉动小，工作平稳，噪声较小，寿命较长，所以被广泛应用于专业机床、自动线等中低压液压系统中。叶片泵分单作用叶片泵（变量泵，*大工作压力为7.0Mpa）和双作用叶片泵(定量泵，*大工作压力为7.0Mpa)。
EALY弋力叶片泵的结构和原理：
定子具有圆柱形内表面，定子和转子间有偏心距e，叶片装在转子槽中，并可在槽内动，当转子回转时，由于离心力的作用，使叶片紧靠在定子内壁，这样在定子、转子、叶片和两侧配油盘间就形成若干个密封的工作区间，当转子按图示的方向回转时，在图的右部，叶片逐渐伸出，叶片间的工作空间逐渐增大，从吸油口吸油，这就是吸油腔。在图的左部，叶片被定子内壁逐渐压进槽内，工作空间逐渐减小，将油液从压油口压出，这就是压油腔。在吸油腔和压油腔间有一段封油区，把吸油腔和压油腔隔开，叶片泵转子每转一周，每个工作空间完成一次吸油和压油，故称单作用叶片泵。
