【技术实现步骤摘要】
油箱总成
本技术涉及车辆油箱领域,尤其涉及一种油箱总成。
技术介绍
油箱总成作为汽车发动机的储油和供油装置,必须具备箱内的油压控制在合理范围内;其中燃料要利用高位差及汽油本身负压源源不断地注入发动机燃烧室,其中,需要燃料油箱与大气保持连通。当油箱内气压突然过大时,需确保其能及时进行泄压,以使得其与大气气压相等。现有技术中,对于油箱内气压突变时泄压往往采用通气阀实现,现有的通气阀只有一排气口,泄压完成后,无法确保其与大气压相等,泄压效果不理想。
技术实现思路
本技术为了解决现有的通气阀只有一排气口,泄压完成后,无法确保其与大气压相等,泄压效果不理想的问题。为了实现上述目的本技术提供一种油箱总成,包括油箱本体和固定在所述油箱本体顶部的通气阀,所述通气阀包括:阀盖,在所述阀盖上开设有通气口,在所述阀盖内设有弹簧和堵块;阀体,其安装在阀盖底部,所述阀体包括密封圈、罩体、浮芯;所述密封圈安装在罩体的顶部,所述密封圈的中部开设有连接通道;所述浮芯滑动的安装在所述罩体内;所述堵块通过弹簧压紧在所述连接通道的顶部;所述浮芯内设有上下相通的排气通道,所述排气通道正对连接通道的底部设置,所述 ...
