摘要：
A valve assembly for a tire pressure management system. The valve assembly includes a housing having an inner chamber (20). The inner chamber is in fluid communication with a first conduit (24) for communicating with a tire pressure management system. The inner chamber is selectively in fluid communication with a second conduit (30) for communicating with a tire. A piston is provided in the inner chamber. The piston has an inner wall portion (78) and an outer wall portion (76). The inner wall portion defines a cavity having a first opening. The first opening is selectively in fluid communication with the atmosphere. A major biasing member (108) is positioned between the inner wall portion and the outer wall portion. The major biasing member contacts the piston to provide a force which biases the piston to place the piston in a closed position. A seal member (110) is disposed around the outer wall portion to provide a seal between the piston and the housing.
摘要（中）：
一种用于轮胎压力管理系统的阀组件。 阀组件包括具有内室（20）的壳体。 内室与用于与轮胎压力管理系统通信的第一管道（24）流体连通。 内室选择性地与用于与轮胎连通的第二导管（30）流体连通。 在内腔中设置活塞。 活塞具有内壁部分（78）和外壁部分（76）。 内壁部分限定具有第一开口的空腔。 第一开口选择性地与大气流体连通。 主偏压构件（108）位于内壁部分和外壁部分之间。 主偏压构件接触活塞以提供使活塞偏压以将活塞置于关闭位置的力。 密封构件（110）围绕外壁部分设置以在活塞和壳体之间提供密封。
