摘要： In one form, a vent apparatus includes an inlet frame, a venting member, and a retainer member. The venting member includes a mounting portion, a weakened area or burst slit, and a domed portion. The mounting portion of the venting member is secured between the inlet frame and the retainer member. The retainer member includes vent retainer portions or tab portions that extend over the burst slit. The vent apparatus is configured to burst when an inlet pressure exceeds a predetermined level, where the tab portions will bend away and the venting member will bend past the tab portions to relieve the pressure. The inlet frame is configured to support against a vacuum pressure acting in the opposite direction, with the tab portions generally free from the load caused by the vacuum pressure.
