In Great Britain December 13, 1944 1 Claim. (Cl. 299-115) This invention has for its object to provide improved liquid fuel nozzles of the swirling-jet type adapted to convey liquid fuel to a common discharge oriilce from either or both of a pair of fuel supply ducts, and adapted for use more particularly with internal combustion prime movers.
The invention comprises the combination with a hollow body part having a pair of supply ducts, of a swirl plug located at the kexit of one of the ducts, an annular swirl plate at the exit of the swirl plug and in communication with the other duct, and a discharge nipple adapted to form a swirl chamber.
In the accompanying drawings. Figure 1 is a longitudinal section and Figure 2 a cross section on the line 2 2, Figure 1, of a liquid fuel nozzle embodying the invention. Figure 3 is a front elevation of a swirl plate forming part of this nozzle.
Referring to the drawings, I employ a hollow cylindrical body part a adaptedat one end to be connected to one end of the outer pipe of a pair of inner and outer pipes b, c. In the other end of the part a and over the adjacent end of the inner pipe c is placed a piece d which is grooved externally to receive liquid fuel from the outer pipe b, and which at its forward end is chambered to receive fuel from the inner pipe c. In contact with the forward ends of the parts a, d is placed a disc e. This is formed with holes f situated opposite an adjacent annular groove'd' around the part d, and these holes open into an annular groove g in the front face of the disc e. At the centre of the disc e is formed a tapered hole which is occupied by a correspondingly tapered swirl plug h, this being held in position by a spring i, the exterior of the plug being formed with helical grooves k through which liquid fuel can now from the inner pipe c. In contact with the front of the disc e is placed an annular swirl plate m having formed in its slots n (Figure 3) which open tangentially into the inner periphery of the plate and which at their closed ends lie opposite the groove g in the disc e. At the front side of the swirl plate m and in contactwith it is placed a nipple o which has a conical bore forming the swirl chamber p. The parts are held together by a shouldered sleeve q which nts over the part a and is secured by another sleeve r in screw thread connection with the part a, accidental slackening of the sleeve r being prevented by a lock nut s.
the swirl chamber p.
By the invention I am able to construct nozzles simple and convariation is made in the passages leading to the swirl plug h and the swirl plate m.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is: v
A liquid fuel nozzle comprising the combination of a body having a pair of liquid fuel passages, a
said passages and formed with holes and a central bore through which fuel can ilow from said passages, a swirl plug situated in said bore, an annular swirl plate having one face in contact with the outer face of said disc and having tangential slots in communication with the holes in said disc, a nipple in contact with the outer face of said swirl plate and having a swirl chamber formed therein, and means securing the parts of the nozzle together.
