The invention provides a vehicle, a seat comfort system, a massager and a valve assembly based on an SMA actuator, the valve assembly comprises a shell, an air inlet channel, an air outlet channel, a valve chamber and an actuating chamber are formed in the shell, a movable valve element is arranged in the valve chamber, and the SMA actuator is arranged in the actuating chamber; the valve chamber is provided with a valve opening used for communicating the air inlet channel and the air outlet channel and a backflow opening used for communicating the air outlet channel and the actuating chamber. The movable valve element can move between the first position used for sealing the valve opening and the second position used for sealing the backflow opening. The SMA actuator can actuate the movable valve element to move from the first position to the second position, and damping is generated when the movable valve element moves from the second position to the first position. When the movable valve element leaves the second position, the backflow opening is opened, and gas in the gas outlet channel flows back into the actuating chamber through the backflow opening to cool the SMA actuator so as to reduce damping and enable the movable valve element to rapidly move to the first position. The reset response speed of the valve assembly is increased.

    本发明提供了车辆、座椅舒适系统、按摩器及基于SMA致动器的阀组件,阀组件包括壳体,壳体内形成有进气通道、出气通道、阀室和致动室,阀室内设置有活动阀芯,SMA致动器设置在致动室内;阀室具有用于连通进气通道和出气通道的阀开口以及用于连通出气通道和致动室的回流口;活动阀芯能够在用于封闭阀开口的第一位置和用于封闭回流口的第二位置之间移动;SMA致动器能够致动活动阀芯由第一位置向第二位置移动,并在活动阀芯由第二位置向第一位置移动时产生阻尼;在活动阀芯离开第二位置时回流口被开启,出气通道内的气体经由该回流口回流至致动室内冷却SMA致动器以降低阻尼使活动阀芯快速移动至第一位置。本发明提高了阀组件的复位响应速度。
