Definitions

  • a delivery valve for a fuel injection pumping apparatus [21] Appl. N0.: 175,510 includes a body portion which is slidable within a bore between a pair of abutments. The bore forms part of a passage between an injection pump and an injection [30] Forelgn Apphcatlmf p'nomy Data nozzle and the member is provided with a valve which Aug.
  • a predetermined volume of fuel is therefore [5 6] References C'ted allowed to flow from the pipe line towards the injection UNITED STATESPATENTS pump, 2,044,629 6/1936 Parker 137/5123 3,547,148 12 1970 Drori 123/139 DP 5 2 D'awmg F'gures DELIVERY VALVES
  • This invention relates to delivery valves for use in liquid fuel pumping apparatus, the valves being of the kind which are disposed in or adjacent the fuel injection pump and which open during an injection stroke to permit fuel to flow to an associated engine and which then close and allow a predetermined quantity of fuel to flow back towards the pump at the end of the injection stroke.
  • the object of the invention is to provide such a valve in a simple and convenient form.
  • a delivery valve of the kind specified comprises in combination, a member slidable within a bore between a pair of abutments, said bore constituting part of the flow passage from the injection pump to the associated engine, and valve means contained within the member and disposed to open when the member has been moved a predetermined amount by the flow of fuel during an injection stroke towards one of said abutments, said valve means opening to allow continued flow of fuel during the injection stroke but closing at the end of the injection stroke, the member then moving into contact with the other abutment thereby allowing a predetermined quantity of fuel to flow back towards the injection pump.
  • FIG. 1 is a diagram of an apparatus including the valve
  • FIG. 2 is a view to an enlarged scale of the valve.
  • a rotary cylindrical distributor member 1 in which is formed a longitudinally extending bore 3.
  • the distributor member is housed in a body 1a and is driven in timed relationship with the associated engine.
  • the bore 3 defines an abutment 4 and this end of the bore communicates with the pumping chamber of an injection pump 1b.
  • a further abutment in the form of a plug 15.
  • a delivery passage 14 which extends outwardly to the periphery of the distributor member and which is arranged to register in turn and during successive injection strokes of the injection pump, with a plurality of outlet ports 14a only one of which is shown, in the body.
  • the outlet ports are connected respectively to the injection nozzles 14b of the associated engine respectively.
  • a cylindrical delivery valve body 2 Slidable within the bore 3 is a cylindrical delivery valve body 2. Formed within the body 2 is a spring chamber having a seating 7 defined at one end. Moreover, for co-operation with the seating there is provided a valve element in the form of a ball 6. The ball is contacted by a spring abutment 9 and the spring abutment 9 locates against one end of a coiled compression spring 8. The other end of the coiled compression spring is located about a stop 10 which extends from a plug 5 serving to close the end of the spring chamber remote from the seating. Adjacent the plug 5 the spring chamber communicates with the periphery of the cylindrical member 2 by way of short radially disposed passages 16 and these are in constant communication with an enlarged portion 'of the bore 3 from which extends the delivery passage 14.
  • a transverse drilling 11 which opens into the spring chamber by way of the seating.
  • the end of the cylindrical member 2 adjacent the abutment 4 is of reduced diameter and defines an annular space 13 which during movement of the cylindrical member as will be described, can be brought into registration with a circumferential groove 12 formed in the distributor member and communicating with the transversely extending passage 11.
  • the ball 6 At the end of the delivery of fuel by the injection pump the ball 6 will close onto the seating 7 under the action of the spring. Moreover, under the action of fuel under pressure in the pipeline interconnecting the pump and nozzle, the cylindrical member will move towards the abutment 4. During this motion the delivery passage 14 is still in register with a delivery port and a predetermined quantity of fuel will flow back towards the injection pump. This flow of fuel will cease when the cylindrical member strikes the abutment 4.
  • a delivery valve for use in a liquid fuel pumping apparatus for supplying fuel to an internal combustion engine, the valve being positioned between an injection pump forming part of the apparatus and an outlet, the delivery valve comprising in combination, a bore, a pair of abutments at the opposite ends of the bore, a member slidable within said bore between the pair of abutments, said bore constituting part of the flow passage between the injection pump and the outlet, valve means contained within the member and disposed to open when the member has been moved by the flow of fuel during an injection stroke of the injection pump into contact with one of said abutments, said valve means opening to allow continued flow of fuel during the injection stroke but closing at the end of the injection stroke, co-operating means on the member and bore for preventing the application of fuel pressure from the injection pump to said valve means until the member has moved a predetermined extent towards said one abutment, the member at the end of the injection stroke, then moving into contact with the other abutment thereby allowing a predetermined quantity of fuel to flow back towards the
  • valve means includes a seating, and a spring loaded valve element-which co-operates with said seating, a passage in the member, said valve means serving to prevent flow of fuel through said passage until the member has contacted said one abutment.
  • a delivery valve as claimed in claim 2 in which said passage includes a transverse portion opening onto the periphery of the member adjacent the end thereof adjacent the other abutment, said transverse portion communicating with a groove formed in the wall of the bore, said member being of reduced diameter at the end thereof adjacent said other abutment, the arrangement being such that as the member moves into contact with the one abutment the transverse portion is placed in communication with the bore adjacent said other abutment.
  • a liquid fuel injection pumping apparatus including an injection pump for supplying fuel to an injection nozzle and a delivery valve disposed adjacent the fuel injection pump, the delivery valve comprising a bore, a valve member slidable within the bore, a pair of abutments at opposite ends of the bore, an inlet from the injection pump communicating with one end of the bore,
