The invention provides a breather valve, an oil tank pressure adjusting method and an automobile, the breather valve comprises a first cavity and a second cavity, the first cavity communicates with the second cavity, the first cavity is provided with an oil inlet used for communicating with an oil tank, and the second cavity is provided with an exhaust port; an adsorption part is arranged in the first cavity and is used for adsorbing oil liquid; a fan is arranged in the second cavity and used for enabling oil steam in the first cavity to enter the second cavity and be exhausted through an exhaust port of the second cavity. According to the oil tank breather valve, when the pressure in the oil tank rises, oil can be adsorbed through the adsorption part in the first cavity, oil steam volatilized by the oil in the adsorption part can be discharged from the exhaust port of the second cavity under the action of the fan, and the breather valve with the design can be arranged at the bottom of the oil tank; the pressure of the oil tank can be reduced by discharging oil steam generated by oil volatilization in the adsorption part in the breather valve, and the problem that when the breather valve is arranged at the top of the oil tank, a vehicle passes through a complex road surface, and consequently the oil tank cannot breathe can be thoroughly solved.
本申请提供了一种呼吸阀、油箱压力调节方法及汽车,其中,该呼吸阀包括第一腔室和第二腔室,第一腔室与第二腔室连通,第一腔室设置有用于与油箱连通的进油口,第二腔室设置有排气口;第一腔室中设置有吸附件,用于吸附油液;第二腔室中设置有风扇,用于使第一腔室中的油蒸汽进入第二腔室,并通过第二腔室的排气口排出。本申请中,在油箱中的压力升高时,可以通过第一腔室中的吸附件吸附油液,吸附件中油液挥发的油蒸汽可以通过风扇的作用从第二腔室的排气口排出,具有这种设计的呼吸阀可以设置于油箱的底部,通过排出呼吸阀内的吸附件中油液挥发产生的油蒸汽,可以实现降低油箱压力,能够彻底避免呼吸阀设置在油箱顶部时,车辆通过复杂路面导致油箱不能呼吸的问题。
