Description
(54) ПОРШЕНЬ ДВИГАТЕЛЯ ВНУТРЕННЕГО СГОРАНИЯ(54) PISTON OF INTERNAL COMBUSTION ENGINE
1one
Изобретение относитс к области двигателестроени и может быть использовано в поршневых двигател х внутреннего сгорани , в частности в охлаждаемых поршн х .This invention relates to the field of engine construction and can be used in internal combustion piston engines, in particular in cooled pistons.
Известны поршни двигател внутреннего сгорани , содержащие образованные корпусом с радиальными ребрами и вставкой полости охлаждени с трубопроводами подвода и отвода жидкости.Pistons of an internal combustion engine are known, comprising formed by a housing with radial ribs and an insert of a cooling cavity with supply and discharge pipelines.
ВIизвестных поршн х возникает трудность образовани потока охлаждающей жидкости вдоль внутренней стенки корнуса , что может привести к повреждению поршн в результате обгорани .In known pistons, it is difficult to form a flow of coolant along the inner wall of the cornea, which can cause damage to the piston as a result of firing.
Целью изобретени вл етс повьпиение эффективности охлаждени .The aim of the invention is to increase the cooling efficiency.
Дл этого вставка выполнена с соединенными с полост ми охлаждени карманами , размещенными между ребрами и опирающимис на них приливами.For this, the insert is made with pockets connected to the cooling cavities located between the ribs and the tides supported by them.
Карманы могут быть вьшолнены из упругого материала, например резины, и со-т ,единены крепежными элементами со вставкой .Pockets can be made of an elastic material, such as rubber, and co-t, united with fasteners with an insert.
На фиг. 1 показан поршень, продольный разрез; на фиг. 2 разрез по А--.А на фиг. 1.FIG. 1 shows a piston, a longitudinal section; in fig. 2 is a section through A — and FIG. one.
Поршень двигател внутреннего сгорани содержит образованные корпусом 1 с радиальными ребрами 2 и вставкой 3 полости охлаждени 4 с трубопроводом 5 подвода и трубопроводом 6 отвода жидкости .The piston of the internal combustion engine comprises the cooling cavities 4 formed by the housing 1 with the radial ribs 2 and the insert 3, with the supply pipe 5 and the liquid discharge pipe 6.
Вставка 3 выполнена с карманами 7, которые соединены с полост ми охлаждени 4 отверсти ми 8.The insert 3 is provided with pockets 7, which are connected to the cooling cavities by 4 holes 8.
;Карманы 7 размешены между ребрами 2 и опираютс на них приливами 9.; Pockets 7 are interposed between the ribs 2 and supported by the tides 9.
Кроме того, карманы могут быть выполнены из упругого материала, например резины, и соединены креп шими элементами 10 со вставкой 3.In addition, the pockets can be made of an elastic material, for example rubber, and connected by fasteners 10 with an insert 3.
При работе поршн охлаждающа жидкость по трубопроводу 5 поступает в полости охлаждени 4 через карманы 7 и отверсти 8, тем самым происходит охлаждение головки и внутренней стенки поршн .During the operation of the piston, the cooling liquid through the pipeline 5 enters the cooling cavity 4 through the pockets 7 and the openings 8, thereby cooling the head and the inner wall of the piston.
После охлаждени охладитель выходит из поршн по трубопроводу 6.After cooling, the cooler exits the piston through line 6.
