Title: Fuel injection pumps
IPC: F02M59/36
Filed: 1973-06-06
Abstract: 1400656 Fuel injection pumps BENDIX CORP 6 June 1973 [8 June 1972] 26948/73 Heading F1A A fuel injection pump comprises a reciprocating piston assembly 30 for pressurizing fuel in a pump chamber 10, a delivery valve assembly 50, and a solenoid operated relief valve assembly 27 which operates independently of the reciprocating piston assembly 30 and includes a valve 20 whose axial movement opens or closes a spill port 3 in the chamber 10 and whose ends terminate outside the chamber 10 so that its axial movement is not biased by pressurized fuel within the chamber 10. The spill port 3 leads to a supply chamber 5, which supplies fuel to the chamber 10 via an inlet passage 6, and communicates with the chamber 10 by means of a groove 2 in the valve 20 when the valve 20 is extended furthest away from the associated solenoid coil 24. A piston 31 of the assembly 30 only pressurizes fuel in the chamber 10 when the port 3 is closed by the valve 20 and the delivery valve 51 of the assembly 50 then opens when the pressure in the chamber 10 overcomes an associated spring 52. In use, the valve 20 reciprocates in accordance to a signal fed to the coil 24 from a sensing device (not shown), and the piston 31 is reciprocated by a spring 33 and cam follower 32 bearing against a cam of an engine (not shown).

Abstract: 737,475. Bolted joints. FJALLSTROM, B. T. H. Oct. 28, 1952 [Nov. 12, 1951; Jan. 19, 1952], No. 27102/52. Class 83 (4). Relates to the edgeways bolting together of slabs of various materials in the erection of houses, tanks, quays, walls, &c. and consists in mounting bolts in the slabs so that limited axial movement without rotation is permitted to facilitate drawing the slabs together by sleeves with right and left-hand threads accessible through recesses in one or both slabs. As applied to composite timber slabs with peat, sawdust or other insulating filling 9, Fig. 1, the bolts 12 have heads 15 and the limited movement required is obtained by screws 13 passing through holes in the heads but not completely screwed down. In a modification the heads 15 are notched and the screws have hooked heads. In another form the heads 15 are polygonal and slide in correspondingly-shaped casings that prevent rotation and keep the insulating filling from hindering the axial movement. Springs between the heads and casings may bias the bolts to the projecting position. For use in concrete, where the bolts are embedded during the casting, the casings 22, Fig. 8, have extensions 27 that prevent the concrete from gripping the shanks 11 of the bolts. A concretereinforcement member 30 is located near the bolt head and a wooden block 29 cores the opening required for the nut and spanner.

Abstract: 756,288. Jet propulsion plant. SOC. NATIONAL D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. Sept. 24, 1954 [Oct. 15, 1953], No. 27714/54. Class 110(3) A rocket has an ejector tube positioned downstream of the rocket with its inlet opening facing the discharge nozzle of the rocket together with means for interrupting the supply of gas to the ejector tube. In the arrangement shown, Fig. 1, the fuel and the combustion supporting fluid are supplied to a combustion chamber 3 by conduits 1, 2, provided with valves 4, 5. The valve members 4a, 5a are actuated by cams 4b, 5b to either cut off or reduce periodically the flow into the combustion chamber. If desired, the flow through one conduit may be continuous and through the other intermittent. The combustion chamber discharges intermittently through the jet pipe 6 into an ejector 7 which is open at its front end to the atmosphere. For maximum efficiency, the plane of the inlet of the ejector should be spaced at a distance, downstream of the plane of the outlet of the jet nozzle, of between one half to twice the diameter of the jet nozzle outlet orifice. The area of the neck of the ejector should be preferably one and a half times that of the outlet orifice of the discharge nozzle. For operating frequencies of between 50 and 150 cycles per second, the divergent angle of the ejector should be generally less than 5 degrees and in any case less than 10 degrees. The divergence of the ejector may increase continuously or in steps on the downstream side. The length of the ejector is preferably less than the distance travelled by sound in one second divided by six times the frequency of the pulsations. The combustion chamber and discharge nozzle 6 may be designed to have a frequency tuned to the frequency of operation. In a modification, Fig. 2, a fixed rocket 3 discharges through a number of ejector tubes 7 which rotate about a shaft 10. The rocket discharge in this case is continuous. In another modification, the ejectors are held stationary and the rockets rotated. The rockets may be inclined to the shaft to cause self-rotation. In another modification, the rockets and ejectors are fixed and a notched disc is rotated between the discharge nozzles and the inlets to the ejectors. In a further modification, the arrangement shown in Fig. 1 is provided with a cowling so that the pressure of the air supplied to the ejector is raised. In a modification of this arrangement, the ejectors 7 may be mounted in a partition which divides the cowling into two parts. The chamber at the rear of the partition may be used for burning reheat fuel. More than one rocket may be provided in the cowling which have a variable area intake and discharge nozzle the areas of which may be varied by mechanical means or by the use of fluid derived from the engine at a point where the static pressure is high. Specification 730,573 is referred to.
