claims. (ci. 15s-31)' (Granted under Title 35, U. S.
sec. 266) The invention described herein `may be manu- Y factured and used by or for the Government for governmental purposes without payment to me of any royalty thereon.
Thisinvention relates to the automatic control of pulse jet heaters, and of the type set forth. in our cop'ending 'applications S. N. 144,566, filed Februarylt. 1950, and S. N. 129,861, now Patent No. 2,643,107, issued June 23, 1953, and in parizingboiler therefor.
An object of this invention is to provide a bauer' capable of supplying a desired vapor pressure charge to a pulse jet heater. y
Another object of this invention is to provide an automatic means of relling a boiler from a reservoir when the fuel in said boiler is suddenly expended to start the pulse jet heater.
In our copending applications vS. N. 144,566 and S. N. `129,861 a starter device is used to heat a spot on a pulse jet heater as Well as feed fuel to the combustion chamber for starting the pulse jet heater. The starter device comprisesa combustion chamber and iiue portion for forming a hot spot on the pulse jet heater, and a boiler for feeding vaporized fuel under pressure to an aspirator which in turn produces a change under pressure of fuel and air for entrance through a valve, which opens when a predetermined pressure .is reached, whereupon said fuel' will enter into the combustion chamber of the pulse jet heater. When this charge comesin contact with the hot spot, combustion of the charge takes place which starts the operation of the pulse jet'heater, whereupon the valve shuts olf the feeding of fuel from the aspirator and boiler. In order to rell the boiler in preparation for subsequent operation of the starter, fuel must be inserted-by hand. The subject invention eliminates the necessity of recharging the boiler by hand and substitutes an automatic pumping means therefor.
It is therefore an object of this invention to provide .an automatic means for rechargingv the starting devicey in Apreparation for subsequent startingof the starter device and pulse jet heater.
A still further object of this invention is to provide apump `between the reservoir and boiler which will automatically respond tothe vapor pressure fluctuation lin said boiler and accordingly'feed fuel` to the boiler when the fuel is suddenly expended and the pressure drops below a predetermined amount.
Another "further object of this invention is to prdvide'a pump comprising an expansible motor chamber andan lexpansible pump chamber con# ticular to the automatic operation of a fuel vapor- 110 "Code (1952),
nected to Ia single pressure responsive surface, th motor chamber communicating with a boiler so as to contain the same vapor pressure as the boiler, the pump chamber communicating with a supply reservoir and boiler through inlet. and outlet check valves respectively, so that upon a drop in vapor pressure in the boiler due to the fuel being charged into the pulse jet beaten-the pressure in said motor chamber will correspondingly drop and operate said pressure responsive surface to compress said pump chamber and force a charge of fluid into said boiler for subsequent starting of the starter device and pulse jet heater,
and upon subsequent starting, the vapor pressure y in the boiler will increase so that the pressure responsive surface in the pump will be operated to extend the pump -chamber and decrease the pressure therein less'than the pressure in thev reservoir whereupon fluid will enter theV expansible pump chamber from the fuel supply reser- Voir.
These and other objects will become more apparent from the accompanying specification and drawings wherein similar parts have likev numbers and where: I Figure 1 shows the preferred embodimentV of the invention of a burner and a boiler with a vapor pressure area and combustion chamber thereinv connected to a pump which in turn is connected to a reservoir; p
Figure 2 shows another type of pump which may be used in place of the pump in Figure 1.
Referring to Figure 1, fuel boiler 2 has a vapor pressure chamber 4 therein surrounding a combustion chamber yl'i having a ilue portion l5. The boiler 2 -contains an outlet 3 through which fuel from the boiler may enter into a pulse jet heater (not shown) when the pressure in said boiler reaches a predetermined value. A wick 5 for starting the boiler is located in the boiler 2. The lower portion of the boiler 2 is provided Iwith longitudinal slots 1 for entrance of air into the combustion chamber 6, and a valve operated vfuel burner nozzle 8- for permitting regulatory fluid flow into the combustion chamber 6 to mix with the air therein. The fuel burner nozzle is pro-I the spring I3. The conduit IS mounted in said boiler surrounds the combustion chamber 6 and extends through said combustion chamber at I8 into the operiing--` 1 3: thefiuel burner. ;A.pump is connected-stothefboiler 2 byfua 'coupling 22. Said pump 20 comprises a housing 24 having a head thereon, said head having an inletgqi` port 2B and outlet port 28 therein 'Saidinletg. and outlet` ports contain ballr chcl:" valvesy and 32.
