Abstract: 1489299 Fuel injection systems NIPPON SOKEN Inc 23 July 1975 [29 July 1974 29 Nov 1974]  30813/75 Heading F1B A fuel injection system for an I.C. engine comprises a sensor 3 for detecting the intake air-flow rate, and a pump 5 and relief valve 6 to supply fuel to a metering device 10 which feeds at least one nozzle 8, and is characterized in that the metering device comprises a housing 11 with at least one fuel outlet 15, a rotor 12 mounted in the housing for rotation in synchronism with the engine, a control member 13 engaging the rotor 12 and axially displaceable by the sensor, the rotor having a slot 18 and the control member having a slit 22, the slot 18 and slit 22 overlapping to an extent determined by the axial position of the control member relative to the rotor, so that fuel is intermittently supplied to outlet 15 in response to rotation of the rotor. Fuel enters housing 11 through inlet 14 and passes through bore 20 to slit 22. Fig. 3 shows a device having four outlets 15 each opening into an arcuate groove 15 which subtends an angle of 30 to 80 degrees. As seen in Fig. 3, slots 18 are wider than slits 22. In a first modification, Fig. 5 (not shown) the slots 18 are narrower than slits 22, which have a greater width than the slits shown in Fig. 3. In a second modification Fig. 7, rotor 12 is inside control member 13' and the slit 22' is wider than the slot 18' as seen in a plane VIII-VIII normal to the rotor axis. In a third modification, Figs. 10 and 11 (not shown) the construction is the same as in the second modification except that the slit 22' is narrower than slot 18'. In a fourth modification, Fig. 15, control shaft 13" is inside rotor 12" and there is an annular groove 22"a around the shaft, which communicates with four slits 22" so that fuel is continuously supplied to radial distribution slot 18". This modification may also include two diametrally opposed slots 18 . In a fifth modification, Fig. 12, a differential pressure regulator is provided to maintain a constant difference between the pressure of the fuel downstream of distribution slot 18 and upstream of the slits 22. The regulator comprises housing 31 divided by diaphragm 34 into upstream chamber 32 and downstream chamber 33. Fuel enters chamber 32 at a rate determined by valve 35, which is mounted on diaphragm 34 and biased by compression spring 37, so that the pressure in chamber 32 is the same as the pressure upstream of slits 22. Chamber 33 is connected by passages 38, 39, 40 and 41 to slot 18 and is therefore at the same pressure as the fuel at outlet 15. The differential pressure regulator can also be used with any of the constructions described above.

Title: Improvements in or relating to apparatus for storing fluid under pressure
IPC: F17C1/00
Filed: 1924-12-30
Abstract: 244,590. Le Mesurier, L. J. Dec. 30, 1924. Storing under pressure.-Gas is compressed into a reservoir surrounded by an outer reservoir receiving gas from the inner reservoir through reducing valves and supplying the gas for use. Fig. 2 shows apparatus comprising two cylindrical reservoirs, one supported eccentrically in the other by lugs A<3>, formed of steel plates with domed end caps. The reservoirs are in communication by a bent pipe C<1> leading from the inner reservoir to an union C mounted in the end of the outer reservoir and fitted with a supply pipe D and a pipe C<2> by which the gas may pass to a reducing valve E controlling its passage to the outer reservoir. When the difference between the reservoir pressures is excessive, fluid passes to the outer reservoir. If the pressure in the outer reservoir is excessive, the gas escapes to atmosphere by a relief valve G. Fig. 3 shows a modified valve arrangement in which the outlet from the inner reservoir and the inlet to the outer reservoir are connected by a passage L controlled by valve J, N, P. If the pressure difference becomes excessive, the valve P, which is subject to the two pressures on its opposite faces, is opened and allows high pressure fluid to pass to the back of the piston K, which moves and opens the valve J connected to it. If the lower pressure falls unduly, a diaphragm N' subject to it is allowed to fall under spring pressure and open the valve N, allowing high pressure fluid to pass to the piston K as before. When the valve J is reclosed, a leak K<2> allows the pressure behind the piston to be relieved.
