Abstract: Disclosed is a pressure compensator for a housing compartment that includes a housing wall that has an opening between an interior zone that is inside of the compartment and an exterior zone that is outside of the compartment. The housing wall also includes an annulus that defines one portion of the opening. A seal engages the annulus and is seated in the opening to seal the opening, the seal including a flexible diaphragm having a normally closed slit therethrough. The seal is configured so that the diaphragm is normally compressed in a first direction that urges the slit closed when the seal is engaged with the annulus. The diaphragm is arranged so that a pressure difference between the interior zone and exterior zone urges the diaphragm to flex in a direction for opening a slit thus creates a pathway between the interior zone and the exterior zone, thereby reducing the pressure difference.

Abstract translation: 公开了一种用于容纳隔室的压力补偿器，其包括壳体壁，该壳体壁在位于隔室内部的内部区域和在隔室外部的外部区域之间具有开口。 壳体壁还包括限定开口的一部分的环。 密封件接合环形空间并且位于开口中以密封开口，密封件包括具有通过其的常闭狭缝的柔性隔膜。 密封件构造成使得当密封件与环形空间接合时，隔膜通常沿着第一方向被压缩，该第一方向促使缝隙关闭。 隔膜被布置成使得内部区域和外部区域之间的压力差促使隔膜沿用于打开狭缝的方向弯曲，从而在内部区域和外部区域之间形成通路，从而减小压力差。
