Abstract
A flap type pressure relief valve comprises a frame having an opening therethrough controlled by a valve flap in the form of a flexible sheet of material mounted to the frame along a first side of the opening to overlie the opening. The flexible sheet is joined to the frame by a connection comprising slots through the frame adapted to receive and retain tabs on the valve flap that extend through the apertures. The tabs are formed of resilient and compressible elastomeric material and have enlarged first and second retaining ribs extending closely adjacent the respective slot on both side faces of the frame with a necked connecting portion disposed between the first and second ribs. The connecting portion of each tab is seated within the respective aperture and is under compression and completely fills the aperture and compressively engages the frame. The retaining ribs hold the valve flap in its assembled location.
