Definitions

  • the present invention relates to a device for feeding fuel to a heater operating on gasoline and having electric ignition means, mainly for automobile use.
  • One of the chief advantages of a heater of this type which operates on gasoline is that it can be used before starting the vehicle.
  • two problems arise: firstly, the fuel feed, and secondly, automatically stopping the heater after a predetermined operating time. These operations are performed without requiring any action from the user, except, of course, for starting the heater operation.
  • the device according to the invention for feeding fuel to a gasoline-operated heater having electric ignition means is characterized in that it comprises a sucking and forcing pump having a variable-volume chamber bounded by a spring-urged movable member such as a flexible diaphragm or a piston operatively connected to an external control member actuatable by the user, this variable-volume chamber communicating on the one hand with the fuel tank through the medium of a non-return valve, and on the other hand with the heater and a switch controlling the electric ignition circuit of the heater, said 3,423,159 Patented Jan.
  • variable-volume chamber of the pump constitutes a fuel reserve which is filled only when the heater is about to be started, the heater being subsequently stopped when this reserve is exhausted.
  • the hazardous permanent storage of fuel in said reserve is definitely avoided.
  • a gasoline tank 1 is adapted to supply fuel to an internal combustion engine 4 by means of a carburetor 3 fed by a pump 2.
  • the gasoline-fed electricignition heater is designated in block form at 5, and may be for example of the type described and illustrated in the French Patent No. 1,409,337 filed on July 7, 1964.
  • the feed system comprises a sucking and forcing pump 6 having a cylinder 7 in which a piston 8 is constantly urged by a coil compression return spring 9. Between this piston 8 and the bottom of cylinder 7, a chamber 11 is formed which is connected to the fuel tank 1 through a pipe line 12 having a nonreturn valve 13 inserted therein. This chamber 11 also communicates through another pipe line 14 with the carburetor controlling the metered supply of fuel to the heater 5.
  • the piston 8 of pump 6 has a rod 15 emerging from the cylinder 7 and according to the specific form of embodiment illustrated in the drawing this rod is adapted to be actuated by means of a pull-knob 16.
  • the heater proper 5 comprises an electric ignition device for example of the type described and illustrated in the above-mentioned French patent, which is not shown in detail in the attached drawing.
  • This device is connected to a source of current 17 through an electric circuit 18 having a switch 19 inserted therein.
  • the control member 21 of switch 19 projects into a longitudinal notch 22 formed in the piston rod 15 so that the end shoulder 22a and 22b of this notch may actuate the switch 19.
  • the electric ignition device of heater 5 is energized and the heater is in its operative condition.
  • piston 8 When the user releases the knob 16, piston 8 is moved slowly to the right, as seen in the figure, by its return spring 9. Thus, the fuel contained in chamber 11 is forced through pipe line 14 into the carburetor supplying the heater 5.
  • the piston 8 may be actuated either directly or by means of a pull-knob 16, as shown in the drawing. Alternately, the rotation of a lever or knob may be used to this end. Similarly, a flexible, accordion-like diaphragm or bellows may be substituted for the piston 8 to improve the fluid tightness.
  • the pull-knob, lever or like member controlling the movement of piston 8 or of a diaphragm may be set in different positions corresponding to different volumes of chamber 11 and therefore to different operating time periods of the heater 5.
  • the piston 8 may be remote-controlled through any suitable means, for example by means of a sliding-core electromagnet of which the energizing current may be adjusted as a function of the desired operating time period of the heater 5.
  • a system operating on gasoline and having electric ignition means comprising a heater, a gasoline tank, a suction and forcing pump having a variable-volume chamber, a movable member bounding said variable-volume chamber, a return spring associated with said movable member, an external control member coupled with said movable member and adapted to be actuated by the user,
  • said movable member of said pump comprises a piston rod fixed to said movable member
  • said control member comprises handle means on said piston rod
  • said piston rod being movable lengthwise and having two spaced abutments thereon
  • said switch comprises an actuating lever positioned for engagement by one of said abutments to close the switch and for engagement by the other of said abutments to open said switch.
  • a device in which a third pipe line branches off of said first pipe line to supply gasoline to an engine and in which a fuel pump is provided in said third pipe line, said non-return valve being disposed between said variable volume chamber and said branching of said third pipe line.
