Abstract
Предложена система топливоподачи для ДВС, преимущественно дизеля, содержащая насос высокого давления, связанный магистралью питания с емкостью для топлива и нагнетательным трубопроводом, связанным, в свою очередь, с системой форсунок, каждая из которых включает полый корпус, в котором размещен распылитель с запорной иглой, нагруженной пружиной, расположенной в надыгольной полости корпуса форсунки и снабженной средством регулировки натяжения пружины, топливоподводящий канал, связанный с нагнетательным трубопроводом и полостью, и сливное устройство, связанное со сливным трубопроводом, причем между топливоподводящим каналом и сливной магистралью через надыгольную полость сформирован канал для слива топлива, а надыгольная полость форсунки выполнена с возможностью гидравлической регулировки давления в ней посредством обратного клапана, между входом и выходом которого расположен запорный элемент, в которой, прежде всего для полного исключения эффекта гидрозаклинивания иглы, обратный клапан установлен с возможностью связи его выхода со сливным трубопроводом. Система предусматривает различные места установки обратного клапана, различные формы выполнения запорного элемента обратного клапана, а также различные формы коммутации сливных трубопроводов форсунок по отношению к обратному клапану.A fuel supply system for an internal combustion engine, primarily a diesel engine, is proposed, comprising a high-pressure pump connected by a supply line to a tank for fuel and an injection pipe connected, in turn, to a system of nozzles, each of which includes a hollow body in which a sprayer with a stop needle is placed, loaded spring located in the naguli cavity of the nozzle body and provided with a means of adjusting the tension of the spring, fuel supply channel associated with the discharge pipe and the cavity, and drain A device connected to the drain pipe, the fuel drain channel being formed between the fuel supply channel and the drain line through the nadygolny cavity, and the nyagi cavity of the nozzle is made with the possibility of hydraulic pressure control in it through a check valve, between the inlet and outlet which, first of all, to completely eliminate the effect of needle sealing, the check valve is installed with the possibility of connecting its output with the drain pipe. The system provides various locations for the installation of a check valve, various forms of execution of the check valve element, as well as various forms of switching the nozzle drain pipes in relation to the check valve.
