Трубопровод 12 снабжен прозрачной вставкой 24, расположенной вертикально и позвоп к цей визуалыю контролировать утеч ки топлива. Устройство работает следукадим образом. Неплотности в соединени х нагнетательного топливопровода 2 привод т к образованию утечек топлива, которое по оболочке 1 и непосредственно вз штуцера 3 собираетс  в кожухе 6. Поступившее j в кожух 6 топливо через отверстие II по трубопроводу 12 поступает в коллектор 13.-В коллектор 13 поступают утечкн топлива от каждого топливного насоса 5, снабженного кожухом 6 и трубопроводом 12. Иа коллектора 13 топливо поступает в резервуар 14. При незначительных утечках топлива, характеризующих нормальное техническое состо ние соединений нагнетательного топливрпровода , оно выходит из резервуара 14 через сливное отверстие 19 и сигнальное устройство бездействует.

Формула изобретени  1.Устройство дл  сбора утечек топлива в нашетательном топливопроводе вввгапгел  внутреннего сгорани , в частности анзел , содержащее {Волочку, расположевнутю нагнетательного топливопровода и св занную с резервуаром сбора топлива, и uiTynep топливного насоса отличающеес  тем, что, с целью повышени  надежности работы путем посто нного контрол  герметичности соединени  в топливной системе, штудер снабжен кожухом, сообщенным с оболочкой и соедшенным с резервуаром трубопроводом. The casing 6 is located in the casing 6, which is hermetically connected by means of sealing cuffs 7 and 8, respectively, with the sheath 1 and the head 4 with the clamping devices 9 and 1O. In the lower part of the casing, there is an opening C through which the pipeline 12 and the collector 13 have an internal volume of the casing communicating with the fuel leakage collection tank 14. The tank 14 contains a perynsfrop level, made in the form of a float 15 with a contact outer surface, hinged on the bracket. 16 and a vaimo action with an eleutric controller 17 connected to the alarm system (not shown) by means of an electrical connector 18. In the lower part of the tank 14 there is a drain hole 19 with a discharge pipe 2O and an overflow 21 with a pipe 22 Drain hole 19 is equipped with the device 23 for adjusting its passage section. Pipeline 12 is provided with a transparent insert 24 located vertically and allowing for visual control of fuel leaks. The device works in the following way. Leaks in the connections of the injection fuel line 2 lead to the formation of fuel leaks, which collects in the casing 1 and directly taking the fitting 3 into the casing 6. The incoming j into the casing 6 through the opening II through the pipeline 12 enters the collector 13.-The collector 13 enters fuel leakage from each fuel pump 5, equipped with a casing 6 and a pipe 12. The collector 13 also receives fuel in the reservoir 14. With minor fuel leaks, characterizing the normal technical condition of the injection connections plivrprovoda, it exits the tank 14 through the drain hole 19 and the signaling device is idle. If the density in the fuel injection pipelines is disturbed, the leakage becomes more efficient, the fuel level in tank 14 rises and when a certain overflow level 21 reaches a certain level, the float 15 closes contact 17, which includes an alarm ycT} device that warns of a disturbed scientific research technical condition of the injection pipe connections. If it is temporarily impossible to eliminate the causes of significant leaks, fuel from tank 14 leaves through an overflow hole 21, the flow area of which is much larger than the drain hole 19 By adjusting the flow area of the hole 19 you can reach the required limit for the normal amount of fuel leaks. The transparent insert 24 allows visual inspection of the tightness of the injection fuel line connections. Such an implementation of the device allows for automated monitoring of fuel leaks in the connections of the fuel injection pipe. improve the reliability of the engine as a whole. 1. An apparatus for collecting fuel leaks in the extension fuel line of an internal combustion engine, in particular ansel containing {Volochka located at the injection fuel line and connected to the fuel collection tank, and uiTynep of the fuel pump, characterized in that Constant monitoring of the leaktightness of the joint in the fuel system, the shader is provided with a housing connected to the shell and connected to the reservoir pipe. 2.Устройство по п. 1, отличающ ее с 9 тем, что кожух выполнен коническим и снабжен уплотнительными манжетами . 2. The device according to claim 1, distinguishing it with 9 in that the casing is made conical and provided with sealing cuffs. 3.Устройство по п, 1, о т л и ч а ю щ е ее   тем, что резервуар содержат сигнализатор уровн  поплавкового типа с электрическим контактом н славное отверстие в нижней части, 3.
