The embodiment of the invention relates to the technical field of valve assemblies, and particularly discloses a valve assembly and a pneumatic comfort system.The valve assembly comprises a valve body, a first valve element, a second valve element, a first elastic piece, a second elastic piece and an actuator, and the valve body is provided with a valve cavity, a first medium opening, a second medium opening and a third medium opening; the valve cavity communicates with the first medium opening, the second medium opening and the third medium opening, the first medium opening and the second medium opening are located in the same side of the valve body, the first valve element is slidably arranged in the valve cavity, the second valve element is slidably arranged in the valve cavity, and the first elastic piece applies first elastic force to the first valve element in the first direction; the second elastic piece applies second elastic force to the second valve element in the second direction, the second elastic force is larger than the first elastic force, the second direction is opposite to the first direction, and the actuator is used for actuating the first valve element to move in the second direction and then actuating the second valve element to move in the first direction. In this way, the manufacturing cost of the valve assembly is reduced.

    本发明实施例涉及阀组件技术领域,尤其公开了阀组件及气动舒适系统,包括阀体、第一阀芯、第二阀芯、第一弹性件、第二弹性件和致动器,阀体设置有阀腔、第一介质开口、第二介质开口和第三介质开口,阀腔分别与第一介质开口、第二介质开口和第三介质开口连通,第一介质开口和第二介质开口位于阀体的同一侧,第一阀芯滑动设置于阀腔内,第二阀芯滑动设置于阀腔内,第一弹性件沿第一方向向第一阀芯施加第一弹力,第二弹性件沿第二方向向第二阀芯施加第二弹力,第二弹力大于第一弹力,第二方向与第一方向相反,致动器用于致动第一阀芯沿第二方向移动,接着致动第二阀芯沿第一方向移动。通过上述方式,本发明实施例实现降低阀组件的制造成本。
