摘要： A pneumatic brake actuator comprising a spring brake actuator with a spring chamber and a spring brake pressure chamber, a service brake actuator coupled with the spring brake actuator including a service brake pressure chamber and a pushrod chamber, a valve body with an interior surface that defines a channel between the spring chamber and the service brake pressure chamber and a seal positioned within the channel in the valve body. The seal and the valve body enclose a valve chamber that is not in fluid communication with the spring chamber or the service brake pressure chamber. The seal is moveable between an open position, in which fluid can flow through the channel, and a closed position, in which fluid is blocked from flowing through the channel. The seal is biased to the open position and comprises a first sealing surface that engages the valve body, when the seal is in its closed position, as well as second and third sealing surfaces engaging the valve body to seal the valve chamber from the spring chamber and the service brake pressure chamber.

摘要： A pneumatic brake actuator has a spring brake actuator with spring and spring brake pressure chambers, and a service brake actuator with service brake pressure and pushrod chambers. A control valve has a seal that is moveable between an open position and a closed position for regulating fluid flow between the spring chamber and service brake pressure chamber. A first surface of the seal is in fluid communication with the service brake pressure chamber and a second surface of the seal is in fluid communication with a valve chamber that is not in fluid communication with the service brake pressure chamber or spring chamber. The seal moves between its open and closed positions based on a pressure in the service brake pressure chamber. Movement of the seal is not dependent on the rate of flow of fluid between the spring chamber and the service brake pressure chamber.

摘要： A pneumatic brake actuator (10) comprising a spring brake actuator (14) with a spring chamber (58) and a spring brake pressure chamber (56). A service brake actuator (12) is coupled with the spring brake actuator (14) and comprises a service brake pressure chamber (38). A valve body (106) of the pneumatic brake actuator defines a channel (142) between the spring chamber and the service brake pressure chamber. A seal (136) is positioned within the channel in the valve body. The seal and the valve body enclose a valve chamber (208) that is not in fluid communication with the spring chamber (58) and the service brake pressure chamber (38). The seal (136) is moveable between an open position, in which fluid can flow through the channel between the spring chamber and the service brake pressure chamber, and a closed position, in which fluid is blocked from flowing through the channel. The seal is biased to the open position and comprises an opening (188), through which fluid flows when the seal is in the open position. The opening extends through the seal in a direction that is aligned with a direction of movement of the seal.

摘要： A pneumatic brake actuator has a spring brake actuator with spring and spring brake pressure chambers, and a service brake actuator with service brake pressure and pushrod chambers. An actuator tube comprises a side wall that defines an interior space which is in fluid communication with the spring chamber. The actuator tube has a first end and a second end, the latter being positioned in the service brake pressure chamber and presents an opening. A valve body is at least partially positioned within the interior space of the actuator tube through said opening and defines a channel. A seal is positioned within the channel, wherein the seal and the valve body enclose a valve chamber that is not in fluid communication with said spring chamber or said service brake pressure chamber. The seal is moveable between an open position in which fluid can flow through the channel between the spring chamber and the service brake pressure chamber and a closed position in which fluid is blocked from flowing through the channel. The seal is biased to said open position and comprises a first surface in fluid communication with the service brake pressure chamber as well as a second surface that is in fluid communication with said valve chamber.
