Abstract

100,928. Timpson, F. M., and Robertson, A. O. Feb. 8, 1916. Safety-valves; valve members and faces.-A combined pressure and vacuum relief valve, of the type in which the pressure-relief valve member carries the seat for the vacuum-relief valve member, has the loading-springs so arranged that they are out of contact with the controlled fluid and may be adjusted without removing the valves from their casing. The pressure-relief valve member 6 contacts with a removable seat 5 screwed into the casing 1, and has a tubular guide-stem 22 adapted to work through an aperture in a plate 16 screwed to the top of the valve chamber. The vacuum-relief valve is guided by a tail-piece 9<1> engaging a grid and formed on the valve seat, and by a spindle 9 passing through the stem 22 and through an adjusting-screw 23 in a bridge-piece 19 carried by the plate 16. The pressure valve is loaded by a spring 27 arranged between the screw 23 and stem 22, while the vacuum valve is loaded by a spring 28 arranged between the bridge 19 and a pair of nuts 25, 26 on the valve spindle 9. The outlet apertures are protected by gauze disks 13, and the whole device is covered by a cover 18 screwed on to the outside of the valve chamber.
