Title: Fuel injection pump for an internal combustion engine
IPC: F02D41/40
Filed: 1974-06-28
Abstract: 1465285 Fuel injection pumps BENDIX CORP 28 June 1974 [28 June 1973] 28903/74 Heading F1A In a fuel injection pump having a rotor 106 which distributes the output in a passage 123 sequentially to delivery passage 124, the actual quantity delivered to each outlet is determined by a pair of electromagnetic spill valves 111, one valve closing to start injection and the other valve opening to end injection. Each valve 111 comprises a valve piston 137 urged towards its open position by a spring 140 and moved to its closed position, shown, by a coil 141. The delivery passage 123 is in permanent communication with an annular chamber 127 around each valve piston 137 through a groove 125 and an annular chamber 109 in the rotor 106 and a respective passage 126. When each valve 111 is open, its annular chamber 127 aligns with an annular groove 128 in the associated valve piston 137, whereby fuel spills from the chamber 127 through a spill path 129-136 to an outlet fitting 142. An electronic circuit causes each valve to open and close at regular intervals, the period of the overlap when both valves are closed determining the quantity delivered. Simultaneous advance or retard of the operations of both valves varies the timing of injection. The pump shown is of the kind having cam ring operated radial pistons 102, but a pump having in-line cylinders provided with pistons (4) reciprocated by a cam-shaft (3) coupled to the distributer rotor is also described, Fig. 1 (not shown).

Title: Gas turbine engine fuel system
Inventor: JOHNSON CHRISTOPHER LINLEY
IPC: F02C7/22
Filed: 1965-07-09
Abstract: 1,093,561. Fluid-pressure servomotor systems. ROLLS-ROYCE Ltd. July 9, 1965, No. 29321/65. Heading G3P. [Also in Division F1] A fuel system for a gas turbine jet propulsion engine 10, Fig. 1, comprises a main control metering orifice 25 and spill valve (not shown), and an additional control upstream or downstream of the main control. The main control is adjusted in accordance with a number of variables, e. g. speed of shafts 21, 22, pressure or pressure ratios in one of the compressors 13, 14, and the mean temperature in jet pipe 18. The additional control comprises a gear pump 31 driven by high pressure shaft 21, a metering orifice 32 adjusted by a needle valve 33 controlled, via a rack and pinion 46 and an electronic actuator 47, by variables such as the speed of shaft 22, the mean temperature at the air intake 12 or jet pipe 18 and compressor temperatures, and a spill valve 35 controlled by the pressure drop across the orifice 32. Since the pump 31 is driven by the shaft 21, any variation in the speed of the latter, e. g. due to failure of the main control with its metering orifice 25 fully open, results in variation of the pressure drop across the orifice 32 and consequent adjustment of spill valve 35. Adjustment of the needle valve varies the shaft speed at which the orifice 32 and spill valve 35 become effective, thereby enabling the speeds of shafts 21 and the temperature in the jet pipe to be reduced below that permitted by the main control. The needle valve 33 has an abutment 50 associated with a pair of adjustable stops 53, 54 to limit adjustment, e. g. within the range of 85-95% to 103% of the maximum speed of shaft 21. Additionally, the orifice 32 or needle valve 33 may be mounted on a bimetallic assembly or a liquid-filled capsule to alter the relative positions between orifice 32 and valve 33 in accordance with changes in fuel density due to changes in fuel temperature. The needle valve may be replaced by a valve arranged to move transversely to the fuel flow, Fig. 2 (not shown). The main and additional controls may use a common spill conduit.

Filed: 1921-11-04
Abstract: 192,191. Edwards, G. T., and Blakeborough, R. A. Nov. 4, 1921. Valves controlled by pilot and relay valves.-A valve device adapted to close in the event of an abnormal flow through the valve has a piston actuated sluice valve member adapted to work in the throat of a Venturi tube and controlled by a pilot valve actuated by the pressure at the throat. The valve b is connected by a spindle c to a piston d controlled by an auxiliary piston valve f so arranged as to connect the two sides of the piston alternately to pressure and exhaust. The auxiliary valve spindle is extended to provide a knob k for hand actuation and is fitted with a movable piece r adapted to be engaged by the shorter arm p<1> of a weighted lever p. The lever p is connected at o to a rod n<1> on a piston n working in a cylinder l and normally held in its raised position by throat pressure admitted through a pipe m. When actuating the auxiliary valve by hand to reset the apparatus the piece r is lifted clear of the lever p<1>. A second piston subject to conduit pressure may be arranged to act on the lever against the action of the piston n. In a modification the two pistons are arranged in a common spindle and actuate a four-way plug-cock through lever and catch mechanism. The sluice valve may be fitted with a ring to close the sump when the valve is open or the inlet may be made smaller than the outlet so that the stream jumps over the sump.

Filed: 1923-11-22
Abstract: 207,540. Siemens-Schuckertwerke Ges. Nov. 23, 1922, [Convention date]. Preserving food for animals.-Green fodder is preserved by heating it by means of rod-like tubular heating- elements 6 embedded horizontally at intervals in the fodder. The heating- elements may also be used as electrodes for passing electricity through the fodder. The material is stored in pits 2, 3, a temporary partition 4 being employed to enclose a certain section while it is filled, the heating-elements 6 projecting through vertical slots in the partition. Covers 7, 9 are arranged over the sections. After completion of the treatment the heating-elements are withdrawn and the slots in the partition 4 may be closed. The next section is then filled, and the partition 4 between the filled sections may then be withdrawn. The heating-elements may be heated by electricity, steam, liquids, or gases, and the elements may have a downwardly projecting rib and may be perforated for the introduction of sterilizing gases or aromatic, nutritious or binding materials such as dextrine, starch, &c. into the fodder. If electric heaters are used they may be connected in series or in parallel with the electrode circuit, and the circuits may be otherwise varied according to local resistance in the fodder. The walls of the pits may be made conductive and earthed.

Abstract: 261,797. Rehmann, H., [Firm of]. Nov. 23, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Charging; charges, agitating.-A rotary agitator 2, 3, for gas producers is mounted on the lower end of a hollow shaft 1 which is automatically raised and lowered by increased and decreased resistance respectively in the body of fuel, cooling fluid being supplied to the parts 1, 2, 3 through a flexible pipe 4. The driving gear for the shaft 1 comprises rings 5, 6, 7 connected together by pivoted links 10, the lower ring 5, which carries the worm-wheel 11 engaging a worm 13 on the driving-shaft 12, being fixed in relation to the shaft 1, while the upper ring 7 is secured to the shaft by its hub 7a and a wedge 14. The upper end of the shaft 1 carries a ring 1<b> which is formed with a pin 25 engaging in a slot in the end of a pivoted lever 26 on which is adjustably secured a weight 26<a>, the latter serving, when the shaft 1 is moving downwardly owing to less resistance in the fuel bed, to augment the weight of the agitator and so cause it to penetrate deeper into the fuel. A sleeve 16, carrying a vertically reciprocating distributing cone 15, surrounds the shaft 1 and is connected by levers 17, 18, Fig. 3, to a crank 19 which is pivoted to a disc 20 mounted on the shaft 21 of the rotary fuel-feeding drum 22, the shaft 21 being driven from the main shaft 12. The lower end of the lever 18 is formed with a pin 18a engaging in a slot 19<a> in the end of the crank 19, this arrangement causing the cone 15 to remain stationary for a short time in its lowest position and so allow an increased feed towards the periphery of the producer. Modifications are described in which the upper ring 7 is formed as friction and clutch couplings, the latter construction being so arranged that, in addition to its rotary motion, the agitator is continuously reciprocated in a vertical direction. The cover of the producer is formed with a normally covered radial or diametric slot to permit removal of the agitator from the producer.

Filed: 1954-10-13
Abstract: 758,176. Centrifugal separators. SMIDTH & CO., AKTIESELSKAB, F. L. Oct, 13, 1954, No. 29535/64. Class 23. [Also in Group XII] In combined apparatus for feeding and preheating powdered or granular material charged into a rotary kiln of the type in which waste gases from the kiln pass in a generally countercurrent direction to the charge material through a series of cyclone separators, hot gases from the kiln 1 pass in turn through a duct 2, a cyclone 3, a duct 4 into which a screw 10 feeds charge material from a storage bin 9, and a second cyclone 5 disposed inside the cyclone 3. The gases are drawn by a fan 8 from the cyclone 5 through a duct 6 and a dust collector 7. Charge material from the dust collector 7 and the cyclone 3 are respectively fed through a duct 13 and a valve-controlled duct 12 to the furnace, and charge material from the cyclone 5 passing through a valve-controlled duct 11 is dispersed in the hot gases ascending the duct 2. The part of the duct 4 which is disposed inside the cyclone 3 is of stream-lined cross section. In a modification, Fig. 4 (not shown), the duct 2 leads to the inner cyclone 5, and in a further modification, Fig. 5 (not shown), the headroom required is reduced by making the feed from the cyclones wholly or in part of horizontal screw conveyers. Another modification, Fig. 6 (not shown), comprises successive pairs of cyclones generally similar to those of Fig. 5. Fig. 7 shows three cyclones 3, 5 and 19 mounted partially inside one another, charge material being fed from the bin 9 by the screw 10 into the duct 20 leading to the third cyclone 19 which discharges through a screw 21 driven by a shaft 23 and a duct 22 into the duct 4 leading to the cyclone 5. In yet another modification, Fig. 9 (not shown), the duct 20 is dispensed with and gases from the cyclone 5 pass to the cyclone 19 through a jacket surrounding the latter, the charge material being also fed into this jacket. A final modification, Fig. 10 (not shown), has a nest of four cyclones disposed within one another. The apparatus may also be applied to cooling hot granular &c. material with cool air.
