摘要:
A flap-type pressure relief valve includes a frame defining a flow opening therethrough with a flexible flap valve element positioned adjacent the frame (12) to overlie the opening (24) and allow fluid flow in a first direction through the opening (24) while preventing flow in the opposite direction. A retainer assembly for joining a peripheral edge portion of the flap valve element (30) to the frame (12) comprises an elongated retainer bar (32) integrally joined to the frame (12) at one edge and connected to the frame at the other edge along a side of the flow opening in overlying relationship to a peripheral edge of the flap valve element (30). The retainer bar (32) has a retainer surface spaced from the frame a distance slightly greater than the thickness of the flap valve element (30). Retainer pins (40) extend from the frame (12) through openings in the flap valve element (30). The assembly thus supports the flap valve element (30) in a freely floating manner without forming air leakage openings.

A headlamp mounting arrangement for an automotive vehicle comprises a mounting support panel (12) which forms a part of the vehicle and a lamp assembly (10) with mounting studs (16) extending outwardly from the rear wall thereof through first openings (30) in the support panel (12). A lock plate (14) is connected to the mounting support panel (12) on the side opposite the lamp assembly (10) for sliding movement between a first position for preventing withdrawal of the mounting studs from the first openings (30) in the mounting support plate and a second position for permitting withdrawal of the mounting studs (16) from the first openings (30). A latch type engagement is provided on the lock plate (14) for preventing undesired sliding movement of the lock plate toward the second position.

A one-way flap-type vehicle ventilation valve comprises a generally planar molded plastic sealing flap (16) for overlying a flow opening formed through a vehicle body panel. The flap is formed in a two shot molding process to have a rigid plastic main body (18) with a resilient plastic seal lip (20) about its periphery. A plastic support shaft (24) is molded integrally with the main body (18) and is spaced therefrom by integral support webs (28). A plastic support is pivotally joined to the support shaft by connecting portions of the bracket that are molded about the ends of the support shaft. Fasteners extend from the bracket for joining the valve to the vehicle body panel. The fasteners include end portions for passing through holes formed through the vehicle body panel adjacent the flow opening.

摘要:
A flap type pressure relief valve (10) comprises a frame (12) having an opening therethrough controlled by a valve flap (14,16,18) in the form of a flexible sheet of material mounted to the frame (12) 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 (46,48) extending closely adjacent the respective slot on both side faces of the frame with a necked connecting portion (50) disposed between the first and second ribs (46,48). The connecting portion (50) 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.
