Abstract

813,260. Fluid-pressure servomotor-control systems; valves. TRIST & CO. Ltd., R. Aug. 11, 1955 [Aug. 12, 1954], No. 23490/54. Class 135. In a valve having a driving magnet separated by a partition from a driven magnet actuating a pair of valve members each .of which cooperates with a seat formed on the end of a passage so that one valve member is seated whilst the other is unseated, the valve members are mounted substantially coaxially in a common frame connected by a mechanical linkage to the driven magnet to permit slight freedom of movement of the frame and so allow the true seating of the valve members. As shown, the driving magnet 7, Fig. 1, is connected to a float 5 responsive to water level in a boiler in a train heating system and the driven magnet 21 to a block 22 connected by a pivot-pin 23 to lugs 18 formed on the boss 16 of the casing cover 2. A frame 39, Fig. 3, mounting valve members 32, 33 controlling passages 12, 13 connected to a supply of compressed air and atmosphere respectively is pivotedly mounted on arms 28 having slotted ends receiving pivot pins 27 which are screwed up hard against the magnet 21 to secure it in the block 22. Split rings prevent the arms 28 sliding axially clear of the pins 27. A pin connecting the arms 28 together has a short mid length 31 (Fig. 2, not shown), slightly smaller than the bore in the boss 16 through which it passes to permit rocking of the arms and frame and hence true seating of the valve members. The adjacent ends of the magnets 7, 21 have like poles so that on movement of the magnet 7, the magnet 21 is repelled. On, for example, the water level in the boiler falling, the float 5 swings downwardly on its pivot-pin 4, the magnet 21 moving the frame to close the valve 32 and open the valve 33 to atmosphere to vent the space 10 above the piston of a piston-actuated boiler feed-water valve 11 so that this valve opens under the action of a spring 19 to supply water to the boiler.
