控制精度高。變量行程短泵的變量是在變量柱塞和限位柱塞作用下，改變定子的偏心距實現的，而定于的zui大偏心距為 5—9mm（根據排量大小不同），變量行程很短。且變量機構設計為高壓操縱，由控制閥進行控制。故該泵的響應速度快。徑向結構設計克服了如軸向柱塞泵滑靴偏磨的問題。使其抗沖擊能力大幅度提高。NACHI液壓柱塞泵　液壓柱塞泵靠氣壓供油的液壓油箱，在每次啟動機器后，必須等液壓漬箱達到使用氣壓后，才能操作機械。直軸斜盤式柱塞泵分為壓力供油型的自吸油型兩種。壓力供油型液壓泵大都采用有氣壓的油箱，也有液壓泵本身帶有補油分泵向液壓泵進油口提供壓力油的。自吸油型液壓泵的自吸油能力很強，無需外力供油。對于自吸油型柱塞泵，液壓油箱內的油液不得低于油標下限，要保持足夠數量的液壓油。液壓油的清潔度越高，液壓泵的使用壽命越長?！〗Y構形式

日本NACHI不二越PVS系列柱塞泵出油閥和出油閥座也是一對精密偶件，配對研磨后不能互換，其配合間隙為0.01mm 。出油閥是一個單向閥，在彈簧壓力作用下，閥上部圓錐面與閥座嚴密配合，其作用是在停供時，將高壓油管與柱塞上端空腔隔絕，防止高壓油管內的油倒流入噴油泵內?！　〕鲇烷y的下部呈十字斷面，既能導向，又能通過柴油。出油閥的錐面下有一個小的圓柱面，稱為減壓環帶，其作用是在供油終了時，使高壓油管內的油壓迅速下降，避免噴孔處產生滴油現象。當環帶落入閥座內時則使上方容積很快增大，壓力迅速減小，停噴迅速。
