Definitions

  • the foregoing requirements of controllably releasing the contents of one or more pressurized bulbs containing a volatile starting fluid to introduce a desired quantity of said starting fluid into the intake system of an internal combustion engine is accomplished by theprovision. of a sealed expansion chamber having a single filling an charging conduit for admitting thepressurized fluid contents from said bulb.
  • Saidsingle conduit forms the only charging means for nited States Patent 0 2,730,093 Patented Jan. 10, 1956 ice said sealed chamber and has disposed therein a perforating means.
  • Said valve means is biased to a closed position by the pressure of fluid in said expansion chamber when the end of said bulb is removed from said charging passageway.
  • Fig.3 is a partial side elevation view in the direction of arrows 3-3 in Fig. 1.
  • a hand-held discharger which includes a body member, designated generally as 19, having formed in the bottom thereof a fixed volume expansion chamber '11 which is substantially sealed from the atmosphere by a piston-operated, pressure-responsive valve means, designated generally as 12, disposed in the single filling and charging means, conduit 1.3, which opens directly into expansion chamber 11.
  • charging passageway 13 provides the sole filling and charging conduit for admitting fluid into expansion chamber 11. Since both the volatile fluid and the operating pressurizing gas are introduced from a sealed, pressurized metal bulb 17, single passageway 13 basedditionally provided therein a hardened steel piercing pin 13 positioned to contact and perforate the perforable end 15 of. bulb 17 when end 19 of the bulb is in sealed engagement with passageway 13 by reason of the sides of end 19 compressing a seal-2i). Bulb 17 is urged into sealing engagement with seal 2% by means of a bulb receiver 21 which is provided with threads 22 engaging complementary threads on the outer surface of single charging passageway 13.
  • a hand-operable valve means 14 is positioned between a discharge tube 15 which has its intake located adjacent the bottom of expansion chamber 11 and a spray nozzle 16 adapted to introduce a spray of volatile material into the intake system of an internal combustion engine.
  • bulb 17 may be filled with any suitable volatile material and subsequently pressurized with a volatile vapor. 'The'perforable end 1% is then sealed by welding or other forms of bonding so that the entire contents of the bulb may be held at elevated pressures upward of 690 pounds per square inch at extremely high temperatures without danger of evaporation or leakage. While such elevated pressures are desirable for use of the bulb in the starting of large internal combustion engines, wherein one or more bulbs may be required in order to successfully start the engine under low temperature conditions, such high pressures are extremely difficult to handle where it is desired to meter a limited .quantity or portion of the contents into an internal combustion engine.
  • the entire contents of bulb 17 are introduced through single charging passageway 13 and through valve means 12 into expansion chamber 11.
  • the pressurized metal bulb 17 contains approximately 10 cubic centimeters of a volatile compound containing diethyl ether and a gaseous component, such as methane or ethylene while the fixed volume expansion chamber 11 has a volume of approximately cubic inches. While in the preferred manner of operation the contents of a single bulb will be discharged into expansion chamber 11 and utilized at will until expended, it is possible for a plurality of bulbs to be successively discharged through the single charging passageway 13 into expansion chamber 11.
  • valve means 12 is disposed in the charging passageway and is of the pistonoperated type, in which a reciprocable valve stem 26 is movable by the pressures appearing on the opposite ends of the piston member 23 formed integral with valve stem 26.
  • Valve stem 26 is normally biased to a position such that expansion chamber 11 is sealed from charging passageway 13 by coil spring 25. However, in operation, the movement of valve stem 26 is effectively under the control of the pressures appearing on the opposite ends of piston member 23.
  • bulb receiver 21 includes a pair of lugs 21A and 21B which facilitate the urging of perforable end 19 of bulb 17 into engagement with the perforating means, pin 18, and moves valve stem 26 to the open position shown so that there is provided free communication through the hollow stem of pin 18 and the valve ports 24 in stem 26. Free communication between bulb 17 and expansion chamber 11 is eifected in this manner to permit the entire contents, both liquid and gas, and the admixed phases thereof in bulb 17 to enter expansion chamber 11.
  • valve stem 26 When it is desired to withdraw bulb 17 from sealed communication with sealed chamber 11 for recharging of the chamber, valve stem 26 is urged into a closed position to seal chamber 11 by the combined pressure of spring 25 and the residual gas pressure in chamber 11 acting on the lower end of piston element 23.
  • a tubular screen 27 is provided below passageway 13.
  • valve 14 may be opened by angular movement of the operating lever means, which includes ring 36, pivoted on body member by movement about the pivot points 37.
  • the lever means also includes a bale-like pivot wire 38 passing through diametrically-opposed pivot points 37, the latter being particularly shown in Fig. 2.
  • Valve 14, preventing'the escape of starting fluid from expansion chamber 11, is held in a closed position by a compression spring 39 compressed between the end of operating ring 36 and the top of body member 10.
  • Spray nozzle 16 may have any suitable configuration for introducing a spray of volatile material into the intake system of an internal combustion engine but, in the preferred form of the invention, is so arranged that an aerosol-type spray is produced under the conditions of pressure normally prevailing in expansion chamber 11. As shown, nozzle 16 includes a filter screen 32.
  • the valve 14 comprises a standing valve seat 33 adapted to engage the outlet end of discharge tube 15.
  • annular sealing ring 34 is provided to surround and engage closely a portion of discharge tube 15.
  • the seal 34 and valve element 33 in the present embodiment are preferably formed of Teflon (polytetrafluroethylene) While numerous modifications and changes will become apparent to those skilled in the art from the foregoing description, all such modifications and changes which fall within the scope of the appended claims are intended to be embraced thereby.
  • a hand-held starting fluid discharger for introducing a charge of volatile material into the intake system of an internal combustion engine comprising a body member having a permanently-sealed unitary expansion chamber of fixed volume therein, a single, charging passageway means forming the only path for entry of fluids into said chamber, means for receiving a starting fluid bulb and urging the perforable end of said bulb into communication with said passageway means, sealing means between said perforable end of said bulb and said passageway means, perforating means disposed in said charging passageway means for releasing the volatile contents of said bulb into said passageway means, first valve means operable by the 9 insertion of the perforable end of said bulb into said passageway means to open said valve means when said bulb is sealed in communication with said passageway means, said valve means being responsive to the pressure of the volatile material in said expansion chamber to close said valve when said bulb is withdrawn from sealing engagement with said charging passageway means, a discharging tube forming a discharge passageway between said expansion chamber and an injection nozzle, said in jection nozzle being adapted
