Description
(54) ГИЛЬЗА ЦИЛИНДРА(54) CYLINDER CASE
с; with;
Изобретение относитс к двигателе строению. По основному авт.св. № 431319 известна гильза цилиндра двигател вну реннего сгорани , снабженна опорным буртом с размещенными, в нем.каналами сообщенными с источником охлаждающей среды, причем каналы соединены ме гду собой кольцевой полостью 1 , Однако в быстроходных форсированных двигател х, в частности в двигателе с противоположно движущимис поршн ми, одной кольцевой полости недостаточно дл эффективного охлавдени поршневых колец, а размещение дополнительных кольцевых полостей при известном их выполнении невозможно из-за ослаблени опорного бур та. Цель изобретени - повышение эф фективности охлаждени гильзы путем образовани дополнительных кольцевых полостей. Указанна цель достигаетс тем, что каналы выполнены пересека ощимис . , , На-фиг.г показан опорный бурт гильзы цилиндра двигател внутреннего сгорани с противоположно движущимис поршн ми; на фиГ.2 - поперечное сечение гильзы по одной из дополнительных кольцевых полостей. Гильза 1 содержит расположенную в ее средней части камеру сгорани 2, ограниченную поршй ми 3 и 4. Камера сгорани 2 уплотй етс , поршневыми кольцами 5 и 6, дл охлаждени которых: опдрный бурТо 7 гильзы 1 содержит пересекающиес каналы 8 и 9, которые, своими входными отверсти ми сообщены с источником 10 охлаждающей среды, а выходными - с кольцевой полостью 11, соединенной с системой охлаждени двигател . Каналы 8 и 9 разделены перемьиками 12 и пересекаютс с образованием дополнительных кольцевых полостей 13 равномерно распределенных This invention relates to a motor structure. According to the main auth. No. 431319 is a well-known cylinder liner in an internal combustion engine, equipped with a support collar with channels located in it communicating with a source of cooling medium, the channels being connected together by an annular cavity 1, However, in high-speed forced engines, in particular in an engine with oppositely moving pistons, one annular cavity is not enough to effectively cool the piston rings, and the placement of additional annular cavities with their known performance is impossible due to the weakening of the support drill . The purpose of the invention is to increase the efficiency of cooling the liner by forming additional annular cavities. This goal is achieved by the fact that the channels are made intersecting existing. ,, Fig. F shows the support shoulder of the cylinder liner of an internal combustion engine with oppositely moving pistons; figure 2 is a cross section of the liner along one of the additional annular cavities. The sleeve 1 contains a combustion chamber 2 located in its middle part, bounded by pistons 3 and 4. The combustion chamber 2 is sealed, by piston rings 5 and 6, for cooling of which: auxiliary bur 7 of the sleeve 1 contains intersecting channels 8 and 9, which the inlets communicate with the source 10 of the cooling medium, and the outlet with the annular cavity 11 connected to the engine cooling system. Channels 8 and 9 are separated by lane 12 and intersect with the formation of additional annular cavities 13 evenly distributed
