Title: Solenoid-operated Poppet Valve
IPC: F16K1/34
Filed: 1979-12-11
Abstract: Flow of high pressure hydraulic fluid between passages 7, 8 and 9 of a manifold 5 is controlled by movement of poppet 32 between valve seats 34 and 35 under the action of biassing spring 25 and solenoid 4. The solenoid region is connected to pressure passage 9 by way of duct 52 to give balanced operation and minimize thickness of casing 15. The poppet 32 is surrounded by cylindrical member 33 with an annular groove communicating with passage 11. Transverse to the direct flow path between the poppet 32 and the passage 11 parallel slots are cut across the end faces and flanges 39 of the cylindrical member 33 to control the fluid flow. In an alternative construction the slots are formed in a central annular region between two ring seats against which a ball-shaped poppet engages. The valve assembly 1 can be reversed with respect to the manifold 5 to connect ports 10, 11 and 12 to passages 9, 8 and 7 respectively to convert from normally closed to normally open operation. <IMAGE>

Supporting insulating members 11 may also be provided, and the elements 8 may be lacquer backed on the side facing the elements 6. The delay circuits 10 may be electrical or acoustical delay lines and are suitably'terminated as by an impedance Fig. 3. The video signal is applied at a source 4 and the delay characteristics are selected so that the total signal is distributed over the panel after the required time interval e.g. 1/25 sec. for a system employing 25 pictures per second. At this instant a flash of radiation 12 is produced thereby reducing the values of resistances 8, sufficiently to allow the voltage pattern distributed along the delay circuits 10 to charge the capacitors 6 and reproduce itself as a visual signal over the elements 6. The delay lines may be sequentially connected or arranged for interlaced scanning or the video signal may be applied to one line only at a time in a straight or interlaced sequence. Means may be provided to compensate for the attenuation of the video signal as it traverses the delay circuit.
