Description

发动机回油管接头总成
技术领域
本发明涉及发动机技术领域，具体地说是一种发动机回油管接头总成。
背景技术
目前国内外发动机回油管接头都是采用机械加工的方法生产的，接头是车辆喷油器回油管系统的关键部件，因其形状特殊，只能将该接头分拆成三部分，分别加工，然后拼装在一起，这种方法生产材料利用率只能达到50%左右，生产成本较高，而且随着使用时间的延长其泄漏率较高，工作不稳定。
发明内容
本发明的目的是提供一种发动机回油管接头总成，其组件三通和两通采用粉末冶金注射成型技术制作而成，无需后加工，材料利用率达到100%，零泄漏点，使用稳定可靠，成本较低。
本发明解决其技术问题所采取的方案是：发动机回油管接头总成，其特征在于：三通与两通均为粉末注射成型技术制造，一体结构，萃取脱脂，然后烧结成型，工作稳定可靠，造价成本低。
本发明的有益效果在于，产品粉末注射成型后烧结成型，无需机械加工，各接口尺寸可以达到较高的装配精度，并达到发动机国Ⅴ排放标准对发动机回油管的各项技术要求。
附图说明
图1是本发明的剖视图。
图2是本发明的结构示意图。
图中标记为：1.两通，2.高压油管一，3.三通一。4.高压油管二，5.三通二, 6.高压油管三, 7.三通三, 8.高压油管四，9.球形接头。
具体实施方式
下面结合附图对本发明作进一步描述：
如图所示，本发明涉及发动机回油管接头总成，其特征在于：两通顺序与高压油管一、三通一、高压油管二、三通二、高压油管三、三通三、高压油管四、球形接头串连。
