Inventor: CC Jones Priordet requested on October 20, 1961 (Great Britain). The present invention relates to such devices for supplying fuel to a fire chamber, which comprise a house closed in one spirit, which house is intended to be connected to a fire chamber. a fire chamber, a hollow shaft extending through said housing, a piston displaceable on the shaft, which is watertightly arranged in relation to the shaft and the housing, and which divides the housing into a first and a second chamber located in each spirit of the housing, a inlet to the first compartment, which inlet is arranged for connection to a magazine with fuel through which the piston can be displaced by the fuel pressure in order to increase the volume of the first compartment, and to fill it with fuel, an inlet designed for the second compartment , which is arranged to be connected to a pressure-cold, and devices by means of which a pressure is exerted on the second chamber in order to displace the piston when the first chamber fills ts with fuel, causes an fuel injection into the fire chamber through the hollow shaft.

Avsikten med uppfinningen är att pa ett enkelt och tillforlitligt satt astadkomma en anordning av ovan angivel slag. The object of the invention is to provide in a simple and reliable manner a device of the type indicated above.

Enligt uppfinningen innefattar sagda anordning en .enda ventil, som reglerar tillforseln av bransle till det forsta rummet och hransleflodet frau del forsta rummet till den ihaliga axelns inre. According to the invention, said device comprises a single valve, which regulates the supply of fuel to the first space and the flow of fuel from the first space to the interior of the hollow shaft.

En utforingsform av uppfinningen askadliggores i langdgenomskarning pa bifogade ritning. An embodiment of the invention is illustrated in longitudinal section in the accompanying drawing.

Pa ritningen visas ,ett cylindriskt hus 1, vars ena ande ar tillsluten genom en integrerande vagg 2, under det att husets andra ande dr fast vid en brannkammares vagg 3. Vid vaggen 2 är fast ena anden av en ihalig axel 4, som stracker sig koaxiellt genom huset 1, vii-ken axels 4 inre dr forbundet med brannkam- Dupl. kl. 24 b: 1/07; 24 li: 7/01 marens hire genom en ventil 5 och en finf8rdelare 6. The drawing shows a cylindrical housing 1, one end of which is closed by an integrating cradle 2, while the other end of the housing is attached to the cradle 3 of a fire chamber. To the cradle 2 is attached one end of a hollow shaft 4, which extends coaxially through the housing 1, vii-ken axles 4 inner dr connected to fire comb- Dupl. at 24 b: 1/07; 24 li: 7/01 maren hire through a valve 5 and a fine distributor 6.

Ph axeln 4 ar en forskjutbar kolv 7 valsketatt anordnad i forhallande till axeln och huset 1, vilken kolv delar huset 1 i ett forsta rum 8 och ett andra rum 9 i husets vardera ande. The shaft 4 is a displaceable piston 7 arranged in a roll relative to the shaft and the housing 1, which piston divides the housing 1 into a first space 8 and a second space 9 in each spirit of the housing.

I vaggen 2 finnes ett radiellt lopp 10, avsett att anslutas till ett under tryck varande branslemagasin, vilket lopp, genom -ett filter 11 och ett ventilsate 12 och darifran runt en lost inpassad ventilkropp 13, ar forbundet med en inloppsoppning 14, som stracker sig axiellt i vaggen 2 och som ar forbunden med rummet 8.. Ventilkroppen 13 paverkas av en fja.der 15 fran satet 12 och stanger, i detta lage, ventilkroppens 13 ande en andra Oppning 16, som star i forbindelse med den. ihd.- liga axelns 4 hire. In the cradle 2 there is a radial bore 10, intended to be connected to a pressurized branch magazine, which bore, through a filter 11 and a valve seat 12 and from there around a loosely fitted valve body 13, is connected to an inlet opening 14, which extends axially in the cradle 2 and which is connected to the space 8. The valve body 13 is actuated by a spring 15 from the seat 12 and, in this position, the spirit of the valve body 13 closes a second opening 16, which is connected to it. ihd.- liga axelns 4 hire.

Anordningen ar sa utford, att det bransle som mata.s genom ventilen 13 till rummet 8, fyller detta rum med bransle under det att rummets volym okas till dess kolven 7 kommer i kontakt med ett stopporgan, vilket, sa.- som visas, utgores av vaggen 3. The device is so challenged that the fuel fed through the valve 13 to the chamber 8 fills this chamber with fuel while the volume of the chamber is increased until the piston 7 comes into contact with a stop means, which, as shown, is formed. of the cradle 3.

Rummet 9 bar intill sin ena ande ett inlopp 17, vilket inlopp alltid utmynnar i det andra rummet 9, oavsett kolvens 7 lage. Detta inlopp star, da anordningen Or i funktion, i intermittent forbindelse med en tryckkalla, vii-ken lampligen kan utgOras av trycket hos den luft som tillfdres brannkammaren. Detta tryck forskjuter kolven 7 sa, att bransle insprutas frau rummet 8. I h&j an filmes ett branslespill bakom ventilkroppen 13. Den sistnamnda är emellertid forsedd med en ansats 13a intill oppningen 14 och kommer det bransletryck som verkar pa ansatsen 13a att forskjuta ventilkroppen 13 mot- fjadern 15 till satet 12 sa, att rummet 8 icke har nagon forbindelse med branslemagasinet.

The room 9 carried next to its one spirit an inlet 17, which inlet always opens into the other room 9, regardless of the position of the piston 7. This inlet is in operation when the device Or is in operation, in intermittent connection with a pressure cold, which can hardly be determined by the pressure of the air supplied to the fire chamber. This pressure displaces the piston 7 so that fuel is injected from the space 8. A fuel spill is filmed behind the valve body 13. However, the latter is provided with a shoulder 13a adjacent the opening 14 and the fuel pressure acting on the shoulder 13a will displace the valve body 13 towards the spring 15 of the seat 12 said that the space 8 has no connection with the trade magazine. At the same time, the movement of the valve body 13 provides a connection between the space 8 and the interior of the hollow shaft 4, so that fuel can be fed to the manifold chamber.
