吸油压油
喷油泵的吸油和压油,由柱塞在柱塞套内的往复运动来完成。当柱塞位于下部位置时,柱塞套上的两个油孔被打开,柱塞套内腔与泵体内的油道相通,燃油迅速注满油室。当凸轮顶到滚轮体的滚轮上时,柱塞便升起。从柱塞开始间向上运动到油孔被柱塞上端面挡住前为止。在这一段时间内,由于柱塞的运动,燃油从油室被挤出,流向油道。这段升程称为预行程。当柱塞将油孔挡住时,便开始压油过程。柱塞上行,油室内油压急剧升高。当压力超过出油阀的弹簧弹力和上部油压时,就顶开出油阀,燃油压入油管送至喷油器。
柱塞套上的进油孔被柱塞上端面完全挡住的时刻称为理论供油始点。柱塞继续向上运动时,供油也一直继续着,压油过程持续到柱塞上的螺旋斜边让开柱塞套回油孔时为止,当油孔一被打开,高压油从油室经柱塞上的纵向槽和柱塞套上的回油孔流回泵体内的油道。此时柱塞套油室的油压迅速降低,出油阀在弹簧和高压油管中油压的作用下落回阀座,喷油器立即停止喷油。这时柱塞仍继续上行,但供油已终止。柱塞套上回油孔被柱塞斜边打开的时刻称为理论供油终点。在柱塞向上运动的整个过程中,只是中间一段行程才是压油过程,这一行程称为柱塞的有效行程。
