    Abstract: Embodiments of a cabin outflow valve having one or more laterally-tapered sealing surfaces are provided, as are cabin pressure controls system including cabin outflow valves. In one embodiment, the cabin outflow valve includes a frame and a first door, which is pivotally coupled to the frame and which is rotated by an actuator between open and closed positions. The first door includes, in turn, a torque input point at which the actuator applies a closing force when rotating the first door into a closed position. A laterally-tapered sealing surface extends along a lateral axis of the cabin outflow valve and has a profile height decreasing with increasing proximity to the torque input point. The laterally-tapered sealing surface helps to ensure the formation of a complete lateral seal when in the first door is rotated into the closed position to significantly reduce or eliminate leakage through the cabin outflow valve.

    Abstract translation: 提供具有一个或多个侧向锥形密封表面的客舱流出阀的实施例，包括舱室流出阀的舱室压力控制系统也是如此。 在一个实施例中，机舱流出阀包括框架和第一门，其可枢转地联接到框架并且由致动器在打开位置和关闭位置之间旋转。 第一门又包括转矩输入点，当转动第一门进入关闭位置时，致动器施加闭合力。 横向锥形的密封表面沿着客舱流出阀的横向轴线延伸，并且具有随扭矩输入点越来越近的轮廓高度而减小。 横向锥形密封表面有助于确保在第一门旋转到关闭位置时形成完整的横向密封，以显着减少或消除通过客舱流出阀的泄漏。

    Abstract: A thrust recovery outflow valve includes a valve frame for mounting on an aircraft exterior skin and a bi-fold valve door that is mounted within the valve frame. The bi-fold valve door includes an aft door section, a forward door section, and a ram air flap. The aft door section is rotatable between an aft door closed position and an aft door full-open position and has a ram air opening formed therein. The forward door section is rotatable between a forward door closed position and a forward door full-open position. The ram air flap is rotationally mounted on the aft door section and is rotatable between a flap closed position, which prevents air flow through the ram air opening, and a flap open position, which allows air flow through the ram air opening.
