Abstract

小型直列式喷油泵由凸轮轴部件、泵体、挺柱体部件、弹簧下座、柱塞弹簧、弹簧上座、齿圈套筒，齿杆及法兰套部件组成。喷油泵为整体封闭式结构，柱塞弹簧采用圆锥螺旋压缩弹簧，使用A型泵的柱塞偶件和出油阀偶件，使易损偶件可与国内外广泛使用的A型泵的偶件通用、互换。弹簧下座端面中心圆孔与一个向一侧开放的豁口相连，使装拆柱塞非常方便。法兰套外圆上下各采用两道密封圈，使密封可靠。

Description

小型直列式喷油泵
本实用新型涉及一种内燃机喷油泵，特别涉及多缸小柴油机所需的小型直列式喷油泵。
对多缸小柴油机来说，当前国内外广泛使用的A型泵，体积太大，而其它小型直列式喷油泵，它们的易损偶件与国外不能通用、互换。
本实用新型的目的是为高速多缸小柴油机提供一种使用A型泵柱塞偶件和出油阀偶件的小型直列式喷油泵，使其易损偶件可与当前国内外广泛使用的A型泵的偶件通用、互换。
本实用新型小型直列式喷油泵由凸轮轴部件、泵体、挺柱体部件、弹簧下座、柱塞弹簧、弹簧上座、齿圈套筒、齿杆及包括柱塞偶件和出油阀偶件的法兰套部件组成。泵体为整体封闭式结构，柱塞弹簧为圆锥螺旋压缩弹簧，这使本实用新型小型直列式喷油泵尺寸比A型泵小而工作能力与A型泵相等，且可使用A型泵的柱塞偶件。弹簧下座中心圆孔与一个向一侧开放的豁口相连，柱塞尾部可从豁口中插入或取出，使更换柱塞偶件比A型泵方便。
下面结合附图说明本实用新型的结构。
图1为本实用新型小型直列式喷油泵的结构图。
图2为弹簧下座的结构图。
如图1所示，小型直列式喷油泵由凸轮轴部件1、泵体2、挺柱体部件3、弹簧下座4、柱塞弹簧5、弹簧上座6、齿圈套筒7，齿杆8及包括柱塞偶件和出油阀偶件的法兰套部件9组成。泵体为整体封闭式结构，柱塞弹簧采用圆锥螺旋压缩弹簧，使喷油泵结构紧凑，可以使用A型泵的柱塞偶件。法兰套外圆上下各采用两道密封圈，使低压燃油腔密封可靠。弹簧下座(图2)中心圆孔与一个向一侧开放的豁口相连，柱塞尾部可从豁口中插入或取出，使更换柱塞偶件非常方便。
