    A fuel injection unit for each cylinder of a diesel engine includes a housing which accommodates a piston pump and an injection nozzle. The piston pump includes a cylinder liner in which a piston runs and controls a flow passage radially extending in the cylinder liner. The flow passage communicates with a supply space which is provided between the housing and the cylinder liner and is divided in vicinity of the flow passage by a baffle sleeve. The so formed two chambers are connected to separate inlet and outlet lines, i.e. that one chamber is connected to the inlet line while the other chamber communicates with the outlet line.

    The invention relates to engine and can be used in diesel fuel equipment.
    The aim of the invention is to improve the uniformity of the tope temperature in the fuel injection units of all diesel cylinders, as well as to increase the efficiency of the separation of air bubbles from the fuel.
    The drawing shows a constructive scheme of the fuel injection unit.
    The unit contains 1 nozzle 2 and a plunger pump, 1 operating plunger 3 and a cylindrical bushing 4, having at least one cooperating with the lunger 3. continuous flow hole 5, communicated with a fuel feeding chamber formed in the housing 1, in a shell in the flow area The holes 5 are fitted with an impact sleeve 6 for dividing the fuel-feeding chamber into two connected with each other, the inner 7 and the outer 8, cavities. In case 1, fuel supply 9 and exhaust 10 channels are made. The inlet channel 9 is separated from the outlet channel 10 by a shock-reflecting sleeve 6, with the entrance to the inlet channel 30 being directed into the internal cavity 7 and located at axial distance relative to the fuel-feeding chamber.
    The anti-reflection sleeve 6 is made 35 centered on the inner shoulder 11 of the housing 1 and mounted on the housing 1 with a support with an axial clearance, and in the area of the upper edge of the shock-reflective sleeve 6 in the housing 1 there is at least one notch 12 for connecting the inner 7 and outer 8 cavities. The feed channel 9 is provided with a filter 13. Plunger 3 is equipped with up40

    equal cutting edges 14, The unit is installed in the cylinder head 1 5 diesel.
    The unit operates as follows. Fuel is supplied to the plunger pump through inlet channel 9, filter 13, internal cavity 7, and flow through hole 5. During the injection stroke of plunger 3, the fuel from the plunger pump is fed through a diesel nozzle. The amount of fuel supplied is determined by the position of the control edges of the 14-plunger 3 relative to the flow hole 5. The flowed fuel from the flow hole 5 enters the internal cavity 7, and from it through the recess 12 and the external cavity 8 into the exhaust channel 10. Organized thus, the circulation of the fuel prevents the accumulation of gas bubbles in the fuel supply chamber, I
    Thus, the use of the proposed fuel injection unit provides an improvement in the temperature uniformity of the fuel across all diesel cylinder assemblies, as well as increasing the efficiency of separating air bubbles from the fuel.
