Abstract

1,220,339. Valves. TRANS-LUX CORP. 8 Dec., 1967 [12 Dec., 1966], No. 59967/68. Divided out of 1,220,338. Heading F2V. An electromagnetic valve comprises a fluidtight chamber 42 arranged to have fluid under a pressure greater than atmospheric supplied thereto, a jet nozzle 90 connected into the chamber, a valve 78 to control a passage into the jet, electromagnetic means 61, 62 to control the valve, a resilient armature 77 connected to the valve, and armature tensioning means 68, 69 to increase the force with which it urges the valve towards the passage as the spacing between the armature and the electromagnet is decreased. The valve is of a plastics material and the armature is secured to a leaf-spring 65 anchored to a post 66. A curved end 68 to the leaf-spring and an adjustable stop-pin 69 form the tensioning means. An iron support plate 77<SP>1</SP> connects the cores 73, 74 of the electromagnets. A number of valves, for separate or simultaneous operation, may be mounted in a common chamber with a single air inlet. The valve may be used in the display system described in Specification 1,220,338.
