Title: Improvements in and relating to carburettors
IPC: F02M17/06
Filed: 1926-05-21
Abstract: 253,095. Soc. Anon. Solex. June 6, 1925, [Convention date]. Spray carburettors. - In a carburettor in which the fuel is maintained at a constant level in an overflow device, manual or automatic means are provided for varying the height of the fuel level relative to the nozzle outlet. Fuel from an inlet j controlled by a valve l passes to a pipe j<1>, the overflow being returned to the reservoir by a pipe k. Spring- loaded tubes d<2>, d<2> are adapted, as the throttle c is opened, to be lowered in succession by a cam c<1> and lever n to increase the height of the pipe j i and thus raise the fuel level. The tube d<2> may be lowered by a hand-lever v. The main and slow-running nozzles a, m are fed through the, conduit d<00>. The valve l is operated by the lever n as the throttle is opened, but at starting is raised by a suctionactuated piston r. A cup t may be provided at the bottom of the main and slow-running nozzles to receive overflowing fuel, or into which fuel may be momentarily caused to overflow, and, in the case of the main nozzle, the cup may be connected to the induction pipe on the engine side of the throttle. The orifice of the nozzle a may be formed in an adjustable cap to vary the height of the fuel delivery. The Specification as open to inspection under Sect. 91 (3) (a) comprises also modifications in which means are provided for varying the relative positions of the nozzle outlet and the fuel level in a float chamber, so that the nozzle outlet is brought below the fuel level. As shown in Fig. 2 (Cancelled), the fuel nozzle comprises a fixed part a over which slides a sleeve a<1> having at its upper end an orifice which, when the sleeve is in its lowest position, forms the fuel outlet and is on a level with the fuel in the float chamber d. The sleeve is provided with orifices a<10> which are sealed when the sleeve is seated on the part a, but which form the fuel outlet when the sleeve is lifted, as the throttle c is opened, by an arm c<1> abutting against a rod f. The position of the rod f relative to the arm c<1> may be varied from a distance by a rod g to vary the time at which the sleeve is raised. In a modification, the float chamber is connected to the nozzle by a flexible or telescopic pipe and is lifted as the throttle is opened by a lever operated bv a cam on the throttle valve spindle. In a further modification, the opening of the throttle lowers a weight which first acts as a displacer. and then rests upon and depresses the float. This subject-matter does not appear in the Specification as accepted.
