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, a linkage piece and an actuator, and the valve body is provided with a valve cavity, a first medium opening and a second medium opening; the first medium opening and the second medium opening are located in the two opposite side walls 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, the first elastic piece applies first elastic force to the first valve element in the first direction, and the second elastic piece applies second elastic force to the second valve element in the first direction. The second elastic force is larger than the first elastic force, the linkage piece is connected with the first valve element and the second valve element, and the actuator actuates the first valve element to move in the second direction through the linkage piece; and then the second valve element is actuated to move in the second direction through the linkage piece. In this way, the manufacturing cost can be saved, and the assembling difficulty can be lowered.
本发明实施例涉及阀组件技术领域,尤其公开了一种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、联动件和致动器,阀体设置有阀腔、第一介质开口和第二介质开口,第一介质开口和第二介质开口位于阀体相对的两侧壁上,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,第二弹性件沿第一方向向第二阀芯施加第二弹力,第二弹力大于第一弹力,联动件与第一阀芯和第二阀芯连接,致动器通过联动件致动第一阀芯沿第二方向移动;接着通过联动件致动第二阀芯沿第二方向移动。通过上述方式,本发明实施例能够节省制造成本和降低装配难度。
