Abstract

1503809 Valves E SIEGWART 23 Dec 1975 [23 Dec 1974] 52550/75 Heading F2V [Also in Division E2] In a pivotal flap valve the outer cylindrical surface of the actuating shaft, on a bush 10 mounted thereon, is engaged by the inner surface of a plastics bearing bush 1 sealingly received in an opening of the duct wall 2, the inner surface being spherically curved in the axial direction. The shaft end is sealed by the spherical engaging surfaces 14, 15 on external flanges of the two bushes and an end wall 4 of the bush 1, which wall may have the centre portion removed inside a circular line of weakening 16 to form a sealing lip to engage a shaft end projecting therethrough. The bearing bush may have an end cap snap-fitted thereto.
