Title: Method of airless fuel injection for internal combustion engines
IPC: F02M45/06
Filed: 1937-12-29
Abstract: 508,945. Fuel-injection pumps. BISCHOF, B. Dec. 29, 1937, No. 35987. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 30, 1938. [Class 102 (i)] [Also in Group XXVII] As shown in Fig. 1. fuel is supplied by a pump having a pressure chamber 14 which communicates past a non-return valve 23 with a conduit 26 leading to an injection nozzle. During inward movement of the pump piston 1, after the pump inlet port 21 has been closed, the valve 23 is raised and an intermittent or continuous preliminary fuel injection occurs until a groove 15 in the piston 1 uncovers the port 21. During further movement of the piston 1, a control edge 17 closes the port 21 and the main injection occurs until an inclined edge 11 opens the port 21. The fuel pressure in the conduit 16 is gradually released. after the injection valve 29 has closed, through bores 24, 25 in the valve 23. To vary the quantity of fuel injected, the piston 1 is rotated by a rack-and-pinion gear 9, 8. In the construction shown in Fig. 3, the preliminary charge is delivered past the valve 29 until a groove 59 in the piston establishes communication with a conduit 57 to allow some of the fuel to enter a chamber 72 in the injection nozzle. After an edge 64 has closed the conduit 57, continued movement of the piston produces the main injection which terminates when an inclined edge 65 opens the conduit 57. A throttling port 56 limits the pressure in the pump, the pressure being higher at high piston speeds.

Filed: 1961-10-14
Abstract: 1,008,520. Respiratory appliances. CAPE ENGINEERING CO Ltd and BYFIELD INVESTMENTS Ltd. Oct. 12, 1962 [Oct. 14, 1961], No. 36947/61. Heading A5T. A respiratory apparatus, which may be used for administering of anaesthetic or for forced breathing, has means for changing from automatic to manual operation or vice versa at will. The changeover is primarily effected by a selector valve assembly comprising three gauged valves 14, 13, 66 and, in the position shown oxygen or. other gas, received through flowmeters 2 or from an emergency supply 65, is fed into a duct 6 and any excess is accommodated in a bag 3. A positive pressure bellows, actuated by a shaft 81, forces it in the direction of the arrows 8 part a mechanically controlled valve 12 and connection 15 to the patient and subsequently, also actuated by the shaft 31, a valve 18 is opened and a second bellows 21 withdraws the gas from the patients lungs, through a carbon dioxide absorber 23 for recirculation, any excess in this case being accommodated in a bag 25. The timing of the breathing cycle is adjusted by a variable ratio gear-box 32 connected to the driving motor 30 and the volume passed at each cycle is adjusted by changing the position of the fulcrum of the lever 40 which extends between the bellows 9 and its actuating crank 37. When the selector valve assembly 66, 13, 14 is rotated anti-clockwise through 90 degrees a switch, not shown, stops the motor 30 and gas from inlet pipe 1 passes directly, through pipe 68, to the part of the circuit to the right of the valves 13, 14, which is now isolated from the rest of the equipment. In addition, a rebreathing bag 60 is connected through non-return valves to this effective part of the circuit so that by manually squeezing and releasing the bag 60 an operator can force gas into the patient's lungs, in the direction of the arrow 8, and withdraw it, through the carbon dioxide absorber 23, as indicated by the arrow 17. Spring loaded relief valves 28, 74, 75 are provided to prevent the building up of excessive pressures and a valve 20 limits the degree of suction which can be applied to the patient.
