Abstract
1. Shutoff flap, comprising one one-piece metallic housing (1), the entire interior area of which is provided with an elastomer coating (13), a centrally supported metallic flap disc (5), which is within a plastic coating (6), a one-piece actuation shaft (7), which is inserted through the flap disc (5), is connected to the flap disc (5) by means of a drive type fastening (11) and is partly surrounded by the elastomer coating (15) of the housing, an upper and a lower shaft bearing (14, 15) which are located in the housing and serve to accomodate the actuation shaft (7) ; identified by the fact that the flap disc (5) is designed in one piece, that the central metallic piece (8) of the flap disc (5) is cut out in the area of the actuation shaft (7), thus leaving two opposite bearing points (9, 10) in the circumference area of the flap disc (5) for accomodation of the actuation shaft ; that, during the coating process of the flap disc (5), the cutout (8) is completely filled with the plastic (6), and that in the area of the two shaft bearings (14, 15) passage ports are (17) provided in the housing for fluid elastomer ; these ports running in the direction of the axis of the acutation shaft (7) so that the fluid elastomer flows around the shaft bearings (14, 15) during the coating process of the housing (1) and covers the shaft bearings.
