| 1. An apparatus for protecting a confined space having a vent aperture for relief of an overpressure condition and provided
with a vent unit having a pressure relief portion across the vent aperture in closing relationship thereto and that opens
when subjected to a preselected overpressure in the protected space, said apparatus including:
recloser structure for at least generally closing off the vent aperture in the event of opening of the pressure relief portion
of the vent unit under said preselected overpressure,
said structure including a resilient flexible recloser panel that in its normal state is of a configuration and in a position
to at least substantially close the vent aperture,
said recloser panel being bent away from and disposed in a location out of the position thereof substantially closing the
vent aperture;
releasable mechanism engaging the recloser panel for normally maintaining the recloser panel in said location thereof out
of closing relationship to the vent aperture; and
an actuator connected to the releasable mechanism for actuating the mechanism to release the recloser panel for movement as
a function of it inherent resilience from said location to said position thereof substantially closing the vent aperture after
the relief portion of the vent unit has opened as a result of said preselected overpressure in the protected area.
