Title: Fuel injection system for an internal combustion engine
IPC: F02B3/06
Filed: 1973-03-21
Abstract: 1426249 Electromagnetic fuel injection nozzles ROBERT BOSCH GmbH 21 March 1973 [22 March 1972] 13540/73 Heading F1B A fuel injection system comprises pump nozzles each having a servopiston 24, Fig. 3 driving a pump piston 25 with pressure fuel being supplied to a pump working chamber 52 via a throttle 26 and an inlet valve 27 and to a servo pressure chamber 29, a valve spool 18 moved by fuel pressure which controls the supply of fuel to the servo pressure chamber 29 in its first switching position Fig. 3 and flow of fuel from the servo pressure chamber to a return line 59 in its second switching position, Fig. 1 a three-port, two position, solenoid control valve 17 which in its open position connects the fuel supply to the valve spool to initiate injection and a two-port, two position solenoid valve 100 which is opened to control the pump charging stroke and thus the stored injection quantity when the valve spool is in its second switching position. An engine driven gear-pump 93 supplies fuel at a pressure determined in dependence on engine speed and/or load by a valve 94. Operation At commencement of the full load injection the servopiston 24 abuts its upper stop owing to the preceding charging stroke. A control 99 (not described) energizes valve 17 causing ball 63, Fig. 1 to engage seat 66 so that valve spool 18 moves to its first switching position in which fuel from line 43, Fig. 3 passes via line 41, chamber 46, passage 74 and bore 22 to the servo pressure chamber 29. Pistons 24 and 25 move downwardly to deliver fuel from the pump working chamber 52 to the nozzle end 55 via passages 51, 53, 53a 53b causing the needle 35 to lift to inject the fuel full load quantity. After injection the solenoid valve 17 is switched to its closed position Fig. 1 so that ball 63 shuts off fuel inlet to the control pressure chamber 21 and relieves the latter via line 65, seat 66 and bore 67 to return line 59. Valve spool 18 returns to its Fig. 1 position in which the servo pressure chamber 29 is relieved via groove 74 to the return bore 57 which with the simultaneous opening of the solenoid valve 100 is connected to the return line 59. The pressure in the pump working chamber 52 drops abruptly, inlet valve 27 is opened and the fuel pressure lifts pistons 24, 25 from their B.D.C. positions during a charging stroke. This continues until the solenoid valves 17, 100 are respectively switched to their open and closed positions to initiate the next cycle. In another embodiment the second solenoid valve 100 is replaced by a second solenoid valve (100a), Fig. 4 (not shown) fitted into the return line so that it can control a return line from a second pump nozzle. A further second solenoid valve (100b) controls the return of fuel flowing back from two further pump nozzles.

Title: Improvements in or relating to centrifugal separation
IPC: B01D17/02
Filed: 1937-05-14
Abstract: 499,024. Centrifugal separators. LOUMIET ET LAVIGNE, J. May 14, 1937, No. 13678. Convention date, May 14, 1936. [Class 23] A fluid mixture is separated into its component parts by its passage under pressure through an helical tube H, the cross-section of which has its major dimension arranged transversely to the axis A of the helix; the tube is divided longitudinally by partitions to segregate the separated components. The entry portion T is of circular section and it is gradually broadened while its sectional area remains constant until it joins the first turn S of the helix. As the tube of the helix broadens, it is divided by an increasing number of partitions 55, 56, 59 and the heavier particles of the mixture in the sections so formed move towards the outer walls of their sections. Consecutive sets of partitions, for instance the sets 56, 59, are arranged so that the heavy particles from one section with the light particles from its adjacent outer section pass together to the next section ahead for re-treatment. All the heavy particles thus eventually arrive at the extreme outer wall where they can be discharged at various stages through the tubes Ex, while the light particles are similarly discharged from the inner wall through tubes E<3> to a common discharge pipe E. Various devices for skimming the heavy or light particles from the sections for re-treatment are described, and carrier fluids may be injected into the flow to assist in the separating action. When, for instance, a flow has been established through the helical tube H, Fig. 22, a fluid mixture may be injected through the pipe I and its components extracted by side tubes E<1>, E<11>. The Specification as open to inspection under Sect. 91 comprises also modifications in which baffles are used instead of partitions, and also a modification in which gas is allowed to expand in a helical tube with an elongated flange-like extension to increase the frictional effect; this produces local heat which may be absorbed by a fluid circulating in a channel about the extension. This subject-matter does not appear in the Specification as accepted.

Abstract: 869,719. Indicating liquid levels. WILLMOTT, A. R. March 15, 1960 [April 23, 1959], No. 13898/59. Class 123(1) A low level indicator particularly for use in a motor vehicle to give a warning of a low level of oil in the engine sump consists of a tube 1 adapted to replace the engine dip-stick, the tube having an open lower end whilst its upper end is connected by a rubber tube 7 to a rubber bulb 8 incorporating a non-return valve mounted beneath the dashboard. Inserted in the tube 7 and mounted so that it is visible to the driver is an indicator unit consisting of a glass tube 9 within a plastic material tube 11 which is cut away at 12 to provide a sight window through which a loosely slidable poppet 10 within the glass tube can be viewed. In use the driver presses the bulb 8 two or three times. If sufficient oil is present in the sump the open end of the tube 1 will be immersed and there will be no return flow of air up the tube as the bulb expands. The poppet 10 will therefore remain at the left hand end of the tube. If the oil level is below the tube end the poppet will move to and fro as the bulb is pressed and released giving an indication of low level. An audible warning is also provided by the sound made as the poppet hits the ends of the tube.
