Daikin油泵柱塞泵V15A2R-95,V15A1R-95

当凸轮轴转到凸轮的凸起部分顶起滚轮体时,

柱塞弹簧被压缩,柱塞向上运动,燃油受压,

一部分燃油经油孔流回喷油泵上体油腔.

当柱塞顶面遮住套筒上进油孔的上缘时

由于柱塞和套筒的配合间隙很小(-)

使柱塞顶部的泵油室成为一个密封油腔

柱塞继续上升,泵油室内的油压迅速升高

泵油压力>出油阀弹簧力+高压油管剩余压力时

推开出油阀,高压柴油经出油阀进入高压油管,

通过喷油器喷入燃烧室.

DAIKIN大金柱塞泵工作回油过程

柱塞向上供油,当上行到柱塞上的斜槽(停供边)与套筒上的回油孔相通时,

泵油室低压油路便与柱塞头部的中孔和径向孔及斜槽沟通,油压骤然下降,

出油阀在弹簧力的作用下迅速关闭,停止供油.此后柱塞还要上行,

当凸轮的凸起部分转过去后,在弹簧的作用下,柱塞又下行.

此时便开始了下一个循环.
