Description

阀芯及包含该阀芯的汽车双联泵限压阀
技术领域
本发明涉及汽车双联泵，特别是涉及一种阀芯及包含该阀芯的汽车双联泵限压阀。
背景技术
现有技术中，机油泵将限压阀设置在排油口处，以防止因泵腔内油压过大，机油从泵体与泵盖的连接处或者其他部件连接处流出，出现漏油现象。
传统的汽车双联泵包括泵盖、燃油泵体、真空泵体以及连接轴，泵盖与燃油泵体之间形成油泵腔，燃油泵体与真空泵体之间形成气泵腔，油泵腔内设置有燃油泵转子，气泵腔内设置有真空泵转子，燃油泵转子和真空泵转子串接在连接轴上，连接轴用于连接外界驱动装置。该装置虽然同时实现了真空泵和机油泵的功能，但是该装置存在的缺点：1)没有将限压阀设置在双联泵的排油管处，仍然会出现漏油的现象；2)在双联泵的长期使用过程中，油泵腔内的燃油会有燃油结块、磨屑等杂质，杂质容易堵塞阀芯与阀体之间的间隙，出现限压阀卡滞的现象，因阀芯移动不到位阀芯的出液孔被堵塞，最终导致限压阀不能使用。
发明内容
本发明的目的是提供一种阀芯及包含该阀芯的汽车双联泵限压阀，通过在阀芯的与弹簧堵头连接的端部设置一圈U型槽，防止了出现限压阀卡滞的现象，同时防止了因阀芯移动不到位阀芯的出液孔被堵塞。
本发明的目的是采用以下技术方案实现的：
本发明提供一种阀芯，在阀芯外壁上开设有一圈U型槽，在阀芯上设置有在U型槽底面上的出液孔，汽车双联泵内设置有油泵腔，汽车双联泵的燃油泵接头上设置有出液通道，出液孔用于将油泵腔和出液通道连通。
本发明还提供一种汽车双联泵限压阀，包括安装在汽车双联泵的排油管上的阀体，阀体内设置有阀芯，阀芯与阀体通过弹簧相连，汽车双联泵内设置有油泵腔，汽车双联泵的排油管的端部上设置有燃油泵接头，在阀芯外壁上开设有一圈U型槽，在阀芯上设置有在U型槽底面上的出液孔，燃油泵接头上设置有出液通道，出液孔用于将油泵腔和出液通道连通。
优选的是，在阀芯的位于油泵腔内的端部上设置有滤网。防止直径较大的杂质进入到限压阀内，延长限压阀的使用寿命。
优选的是，弹簧通过堵头与阀芯相连。实现弹簧在阀芯上的固定。
由于采用了上述技术方案，本发明具有以下优点：
通过在阀芯的与弹簧堵头连接的端部设置一圈U型槽，防止了出现限压阀卡滞的现象，同时防止了因阀芯移动不到位阀芯的出液孔被堵塞，延长了限压阀的使用寿命。

图2为阀芯的剖视图；
图3为汽车双联泵限压阀的剖视图。
具体实施方式
为了使本发明实现的技术手段、创作特征、达成目的与作用更加清楚及易于了解，下面结合附图和具体实施方式对本发明作进一步阐述：
实施例1：
如图1以及图2所示，本实施例提供一种阀芯1，在阀芯1外壁上开设有一圈U型槽11，在阀芯1上设置有在U型槽11底面上的出液孔12，汽车双联泵内设置有油泵腔，汽车双联泵的燃油泵接头5上设置有出液通道，出液孔12用于将油泵腔和出液通道连通。
本实施例的工作原理：当有燃油从出液孔12流出时，杂质同时从出液孔12内流出来，由于阀芯1与阀体2之间的缝隙较小，因此杂质会被挡在U型槽11内，杂质不会进入到阀芯1与阀体2之间的缝隙内，防止了出现限压阀卡滞的现象，同时防止了因阀芯1移动不到位阀芯1的出液孔12被堵塞，延长了限压阀的使用寿命。
实施例2：
如图1至图3所示，本实施例提供一种汽车双联泵限压阀，包括安装在汽车双联泵的排油管3上的阀体2，阀体2内设置有阀芯1，阀芯1与阀体2通过弹簧4相连，汽车双联泵内设置有油泵腔，汽车双联泵的排油管3的端部上设置有燃油泵接头5，在阀芯1外壁上开设有一圈U型槽11，在阀芯1上设置有在U型槽11底面上的出液孔12，燃油泵接头5上设置有出液通道，出液孔12用于将油泵腔和出液通道连通。
在阀芯1的位于油泵腔内的端部上设置有滤网7。防止直径较大的杂质进入到限压阀内，延长限压阀的使用寿命。
弹簧4通过堵头6与阀芯1相连。实现弹簧4在阀芯1上的固定。
本实施例的工作原理：当油泵腔内的压力过大时，油压推动阀芯1，使得弹簧4被压缩，当出液孔12滑动到出液通道所在位置时，出液孔12与出液通道连通，燃油从出液孔12流出，杂质同时从出液孔12内流出来，由于阀芯1与阀体2之间的缝隙较小，因此杂质会被挡在U型槽11内，杂质不会进入到阀芯1与阀体2之间的缝隙内，防止了出现限压阀卡滞的现象，同时防止了因阀芯1移动不到位阀芯1的出液孔12被堵塞，延长了限压阀的使用寿命；当油泵腔内的压力较小时，在弹簧4的回复力作用下，阀芯1回位，出液孔12与出液通道不连通。
尽管本发明的实施方案已公开如上，但其并不仅仅限于说明书和实施方式中所列运用，它完全可以被适用于各种适合本发明的领域，对于熟悉本领域的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本发明并不限于特定的细节和这里示出与描述的图例。
