Abstract: 1522954 Fuel injection pumps; IC engine fuel injection systems CAV Ltd 24 Oct 1975 [1 Nov 1974] 47296/74 Headings F1A and F1B In a fuel system for an I.C. engine wherein a piston 11 performs a pumping stroke in a cylinder 10 when actuating fluid controlled by valving 27, 28 is supplied to one end of the cylinder, fuel previously admitted to the other end of the cylinder through valves 23, 20 is displaced to an outlet 13 until, at the end of the stroke, the valve 20 is opened by the piston and the fuel flows into a cylinder 24 containing a spring-loaded shuttle 25. The return stroke of the piston 11 commences as soon as a stack of Piezo-electric crystals 32 are de-energized to open the valve 28 and release the actuating fluid, the fuel displaced to the cylinder 24 and fuel from a source 22 then flowing into the cylinder 10 through a passage in the valve element 19 of the still open valve 20. Movement of the piston is sensed by a coil 34 and when sufficient movement has occurred, the crystal stack 32 is partially energized to also close the valve 28. This causes the fuel supply pressure to act on the head 21 of the valve element 19 and force it to seat. When the next pumping stroke is required the crystals 32 are fully energized to cause the opening of the valve 27 and the supply of activating fluid from an accumulator 17. Valves 27, 28 are actuated by pistons 29, 30 displaced by liquid moved by a piston 31 subjected to the expansion and contraction of the crystals 32. Fuel leaving the outlet 13 flows to an injection nozzle 14 having a valve element 15 loaded by pressure from the accumulator 17.

A portable code generator 2 (Fig. 1) for feeding data to digital computers &c., comprises a loud-speaker 5 or other acoustic signal source controlled by a dial 3a, by a keyboard, punched tape or some other operating device. In use the generator 2, or at least the acoustic signal source, is fitted in self-holding manner to a telephone mouthpiece 21. In use, the operating device produces a signal train containing a digitally coded message. In one embodiment (Fig. 2) an oscillatory circuit, comprising a capacitor 7 and coil 8 in parallel, is connected to the emitter of a transistor 6, the base of which is connected to a constant bias voltage. The coil 8 is inductively coupled to a further coil 9 whereby current variations caused by the collector current induce in-phase voltages in the coil 8 and undamped oscillations occur. A contact 10 closes and opens rhythmically when the dial 3a is released, to connect a battery 4 intermittently to the oscillator circuit. A pulse train is thereby produced. Alternatively, an oscillator 20 (Fig. 3) is capable of producing two frequencies. A battery switch 16 is closed when the dial 3a is in use. A contact 10<SP>1</SP> intermittently connects in a capacitor 17 on release of the dial 3a whereby frequencies are generated alternately by oscillatory circuits 7, 8 and 7, 8, 17. A third embodiment (Fig. 4, not shown) uses three oscillators (12, 13, 14) of frequencies f 1 , f 2 , f 3 . When the dial (3a) is released pulses at frequency f 1  alternate with "intervals " at frequency f 2 . When the dial (3a) returns to its normal position the signals at frequencies f 1  and f 2  cease. End of transmission is indicated by pressing a key (20), thereby signalling the frequency f 3 . Alternatively, end of transmission may be indicated by a multi-digit code number. Where the data input is provided by punched tape, this is prepared by an auxiliary device. The tape is pulled through the code generator by a drive mechanism (not shown). The dial may have interchangeable cam-plates having different relationships between the width of the raised portions and the width of the " dwells " of the cam-plates. A secret combination of digits may switch on the computer. The loudspeaker may be in a small housing for fitting to the telephone mouthpiece while the remaining parts of the generator are in a second housing for placing on a table top.
