Abstract
1356243 Valves PHILIPS GLOEILAMPENFABRIEKEN NV 23 Feb 1973 [25 Feb 1972] 8982/73 Heading F2V A non-return valve has a flat-faced displaceable valve member 4 co-operating with a seating ring 3 whose initial inner and outer diameters d, D respectively decrease and increase with increasing axial distance from its flat seating surface 6 so as to give increasing radial thickness of the ring. Valve member 4 is of nickelchromium steel of initially greater hardness than the chromium-nickel steel of ring 3 such that the latter undergoes initial plastic deformation under the closing force of member 4 so as to increase the area and hardness of seating surface 6. The compositions and hardness values of the steels are specified. The closing action on member 4 is exerted by spring 7 and/or fluid pressure. In a modification (Fig. 2, not shown) the rounded surfaces a 1 , a 2 of ring 3 are replaced by bevels. The valve may be in the inlet or outlet of a compressor.
