Abstract
Description
Изобретение относитс к машиностроению , преимущественно к топливн насосам двигателей внутреннего сгорани , Известны топливные насосы двигат лей внутреннего сгорани , содержащи корпус из легкого металла, закрепле ную в нем гильзу с регулирующими отверсти ми и камерой всасывани , причем в цилиндрическом отверстии гильзы размещены поршень дл измере ни подачи горючего, снабженный по меньшей мере одной наклонной направ л ющей кромкой, а в расширении цилиндрического отверсти гильзы размещены нагнетательный клапан, корпу которого закреплен в гильзе при пом щи ниппел , св занного с ней резьбовым соединением, причем гильза сопр жена с корпусом через опорный бурт, размещенный на ее наружной поверхности над регулирующими отвер сти ми 1 . Недостатком известного насоса вл етс то, что крепление гильзы в корпусе не обеспечивает достаточной жесткости соединени , что приво дит к по влению изгибающих усилий при работе насоса и к снижению надежности гильзы и насоса в целом. Цель изобретени - повышение надежности путем устранени -изгибающих усилий. Поставленна цель достигаетс тем, что гильза выполнена с фланцем, расположенным в зоне резьбового соединени и имеет уменьшенный диаметр в зоне ниже камеры всасывани дл установки в корпусе с зазором. На чертеже представлен насос,прюдольный разрез. Топливный насос содержит корпус 1, в котором закреплена гильза 2 с камерой 3 и нагнетательным клапаном 4. Гильза 2 сопр жена с корпусом 1 при помощи опорного бурта 5, размещенного на наружной поверхности гильзы 2 над ее регулирующими отверсти ми 6. Ниппель 7 св зан с гильзой 2 резьбовым соединением 8, На гильзе выполнен фланец 9, расположенный в зоне резьбового соединени 8,а в зоне ниже камеры 3 дл установки в корпусе 1 с зазором гильза 2 имеет уменьшенный диаметр. При сборке насоса зазор между гильзой 2 и корпусом 1 компенсирует наружные, силы, возникающие при монтаже и предохран ет гильзу от короблени . Фланец 9, расположенный вThe invention relates to mechanical engineering, mainly to fuel pumps of internal combustion engines. Fuel injection pumps for internal combustion engines are known, comprising a body of light metal, a sleeve with control holes and an intake chamber mounted in it, and a piston for measuring fuel supply, provided with at least one inclined guide edge, and in the expansion of the cylindrical opening of the sleeve there is a discharge valve, the body of which is Replen in the liner using the nipple connected to it by a threaded connection, the liner being coupled to the body through a support shoulder located on its outer surface above the adjusting holes 1. A disadvantage of the known pump is that the mounting of the sleeve in the housing does not provide sufficient rigidity of the connection, which leads to the appearance of bending forces during the operation of the pump and to a decrease in the reliability of the sleeve and the pump as a whole. The purpose of the invention is to increase reliability by eliminating bending forces. This goal is achieved by the fact that the sleeve is made with a flange located in the area of the threaded connection and has a reduced diameter in the area below the suction chamber for installation in a housing with a gap. The drawing shows the pump, pryudolny incision. The fuel pump includes a housing 1 in which a liner 2 is fixed with a chamber 3 and a discharge valve 4. The liner 2 is coupled to the housing 1 by means of a support collar 5 placed on the outer surface of the liner 2 above its regulating openings 6. Nipple 7 is connected a sleeve 2 with a threaded connection 8; A sleeve 9 has a flange 9 located in the area of the threaded connection 8; and in the area below the chamber 3 for mounting in the housing 1 with a gap, the sleeve 2 has a reduced diameter. When assembling the pump, the gap between the liner 2 and the housing 1 compensates for the external forces arising during installation and prevents the liner from warping. Flange 9 located in
