    2. The pipeline of claim 1, in which the intake manifold is provided with at least one threaded fastening element and one protrusion made with an opening for accommodating the fastener, and the latter is configured to be fixed on the engine intake manifold and supporting fixtures on the collector.
    3. A pipeline according to claim 1, in accordance with claim. in order to simplify the design, the support device is made in one piece with the intake manifold.

    This invention relates to mechanical engineering, in particular to intake pipes for an internal combustion engine.
    Inlet pipes for an internal combustion engine are known, which contain fuel sources, an intake manifold with sockets for accommodating fuel injectors, a retaining element and means for securing the retaining element on the intake manifold made with at least one C-shaped leaf spring, one the end of which is fixed with the possibility of rotation on the supporting device WITH
    However, in the known intake manifolds, each nozzle is fixed by a separate holding element, and therefore the assembly and disassembly of the nozzles is difficult.
    The aim of the invention is to simplify assembly and disassembly.
    The goal is achieved by the fact that in the intake pipe containing fuel nozzles, an intake manifold with sockets for accommodating fuel nozzles, a retaining element and means for fixing the retaining element on the intake manifold made with at least one C-shaped leaf spring, one end which is fixed to rotate on the support device, the retaining element & nt is made in the form of a plate, equipped with sockets — for fixing all the fuel injectors and at least one Forging for a C-shaped leaf spring, the free end of which is made with the possibility of elastic entry into the corresponding punching plate.
    2
    In addition, the intake manifold is provided with at least one threaded fastener and one protrusion made with a hole
    to accommodate the fastener, and the latter is arranged to be fixed to the engine intake manifold and the support tool on the manifold.
    o Moreover, the support device 1e is made in one piece with the intake manifold.
    FIG. 1 shows the proposed intake manifold, a perspective view; in fig. 2 - section AA one; in fig. 3 section B-5 in FIG. in fig. 4 - holding element, a perspective view.
    The intake manifold (FIG. 1) contains fuel nozzles 1, an intake manifold 2 with four nozzles 3, each of which is provided with a projection k having a seat 5 (FIG. 2) for accommodating a corresponding fuel
    nozzles 1 and a fuel supply nozzle 6 that is coaxial with the nest 5, supplying fuel to the engine intake duct, retaining element 7 and means for securing the retaining element 7, made in the form of two C-shaped leaf springs 8, the ends 9 of which are rotatably fixed to the support 10 (figure 3).
    The retaining element 7 is made in the form of a plate, equipped with four
    sockets 11 (FIG.) for fixing all the fuel injectors 1 and two punches 12 into which the free ends of the 13 C-shaped front springs 8 elastically enter
    Each fuel injector 1 (FIG. 2) is sealed in slot 5 with protrusion k by means of elastic seal 1, and jacks 11 of retaining element 7 have elastic sealing screws 15, which ensure reliable fixation of fuel nozzles 1. Inlet manifold 2 has a flange 16 s two protrusions 17 formed with holes 18 for accommodating threaded fasteners 19 which, together with nuts 20, secure the intake manifold 2 to the engine and at the same time fix the support 10 to the intake manifold 2. The installation and disassembly of the intake manifold is as follows. FIG. 1 shows the intake manifold assembled. To inspect or replace the fuel injectors .1, the free ends of the 13 C-shaped leaf springs B must be pulled out by hand from the stampings 12, in connection with p. than the holding member 7 is released and has the ability to move upwards. At the same time, the fuel injectors 1 are also freed. They have the possibility of escaping the protrusions from the sockets 5, and thus the inspection or replacement of the fuel injectors 1 is provided. When the inlet pipe is installed, the fuel injectors 1 are installed in the sockets 5 and. pulling the retaining element 7 over them ensures that they are securely fixed relative to the intake manifold 2, and by inserting the free ends 13 of the C-shaped leaf springs 8 into the corresponding extrusions 12 a reliable contact of the nozzles 1 to the slots 5 is achieved. The ends 13 are transmitted along the axis of the fuel injectors 1, in connection with which any gap between the ends of the fuel nozzle 1 and slot 5 is automatically selected, thereby achieving a constant state of the junction between the injectors 1 and 5 nezdami projections 4. Thus, the mounting and dismounting of the inlet pipe is produced without the use of hand tools. To simplify the design, support elements can be made in one piece with the intake manifold 2, .e. with his lips. Thus, the proposed inlet manifold simplifies its installation and disassembly.
