    Abstract: A cap member in a vacuum-operated check valve for relieving backflow pressure received at the control chamber. The cap member has a head member surrounded by a plurality of openings in communication with the control chamber. A flexible plate retained on the head member is seated on the cap member over the openings to form a closed control chamber permitting the vacuum to operate a power brake system. The flexible plate is resilient enough to be unseated by back pressure of a predetermined value received in the control chamber. Thus, internal damage to the check valve is prevented.

    Abstract translation: 用于减轻在控制室处接收的回流压力的真空操作止回阀中的盖构件。 盖构件具有由与控制室连通的多个开口包围的头部构件。 保持在头部构件上的柔性板被安置在盖构件上方的开口上,以形成允许真空操作动力制动系统的封闭的控制室。 柔性板具有足够的弹性,以通过在控制室中接收的预定值的背压而脱离。 因此,防止止回阀的内部损坏。
