Abstract: An airvalve assembly for a brake booster includes first and second members movable relative to each other to allow the passage of fluid, and a clip. The clip engages one of the first or second members, and has a spring arm which engages the other of the first or second members to normally position the first and second members relative to each other.

Abstract: An apparatus and method are provided for adjusting the axial distance between the front and rear walls of a vacuum booster, from outside of the booster, after the booster has been assembled. The booster includes a housing having a front housing and a rear housing joined together and defining a longitudinal axis of the booster. The front housing defines a front wall of the housing and an inner surface of the front wall. The rear housing defines a rear wall of the housing and includes a captive nut having threads adapted for threaded engagement with a threaded end of a tie rod. The front and rear walls are spaced an axial distance from one another along the longitudinal axis. A tie rod extends axially through the housing and has a first end engaging the rear wall of the housing and a second end engaging the front wall of the housing. The first end of the tie rod has threads for engaging the threads of the captive nut in the rear wall of the housing. The second end of the tie rod has an axially facing surface thereof for applying an axially directed force against the inner surface front wall of the housing. The axial distance of the housing between the front and rear walls of the housing is adjusted by turning the tie rod, to thread the first end of the tie rod farther in or out of the captive nut. The captive nut may include a tube extending axially therefrom along a part of the tie rod into the interior of the housing, through one or more separate fluid chambers within the booster, to provide a sealed passageway precluding leakage between the fluid chambers along the tie rod

Abstract translation: 提供了一种装置和方法，用于在增压器组装之后调节来自增压器外部的真空助力器的前壁和后壁之间的轴向距离。 升压器包括壳体，其具有连接在一起并限定助力器的纵向轴线的前壳体和后壳体。 前壳体限定了壳体的前壁和前壁的内表面。 后壳体限定了壳体的后壁，并且包括具有适于与拉杆的螺纹端螺纹接合的螺纹的固定螺母。 前壁和后壁沿着纵向轴线彼此间隔开一个轴向距离。 拉杆轴向延伸穿过壳体并且具有接合壳体的后壁的第一端和接合壳体的前壁的第二端。 拉杆的第一端具有用于接合壳体后壁中的固定螺母的螺纹的螺纹。 拉杆的第二端具有轴向相对的表面，用于向壳体的内表面前壁施加轴向力。 通过转动拉杆来调节外壳在前壁和后壁之间的轴向距离，以使拉杆的第一端更远离紧固螺母。 固定螺母可以包括沿着拉杆的一部分沿着该杆的一部分轴向延伸到壳体的内部的管，其通过增压器内的一个或多个分离的流体室，以提供密封通道，以防止沿着拉杆的流体室之间的泄漏
