Изобретение относитс  к двигателестроению , а именно к конструкци м форкамер,преимущественно дл  роторных двигателей, работающих с факельным зажиганием. Известны форкамеры, содержащие корпус с каналами дл  подвода возду и отвода продуктов сгорани ,топливо подвод щую форсунку,свечу зажигани  В этих форкамерах впрыск топлива на стенки камеры создает неблагопри  тные услови  дл  организации однородной топливовоздушной смеси, что снижает полноту сгорани  топлива. Известны также форкамеры дл  двигателей внутреннего сгорани , содержащие «орпус с каналами дл  подвода воздуха и отвода продуктов сгорани , топливоподающую форсунку, свечу зажигани  и тепловой экран, расположенный между форсункой и свечой 2. Недостатками известных форкамер . вл ютс  накачес венна  очистка от .продуктов сгорани  объема камеры,об зованной вокруг электродов свечи ст кой экрана,и неоднородность слоев т ливово.здушной смеси,возникающа  из за вращательного движени  зар да в форкамере, привод щего к обеднению е-кеси в районе расположени  эле1№рОдов свечи и, как следствие, снижению полноты сгорани  топлива. Цель изобретени  - повышение полноты сгорани  топлива. Указанна  цель достигаетс  тем, что тепловой экран выполнен в виде полого конуса, размещенного с зазором относительно стенок корпуса форкамеры , со стороны вершины которого соосно с ним расположена форсунка и тангенциально каналы дл  подвода воздуха , а со стороны основани  - свеча зажигани  и канал дл  отвода продуктов сгорани . На фиг.1 изображена форкамера; на фиг. 2 -сечение А-А на фиг. 1. Форкамера содер ит корпус 1, сверху Прикрытый крышкой 2. 3 рабочей полости ка.меры расположен тепловой экран 3, выполненный в виде полого конуса . Соосно с экраном в верхней крышке расположена форсунка 4 и здесь же (в плоскости поперечного сечени  А-А) с тангенциальным выходом на рабочую поверхность размещены каналы 5 дл  подвода воздуха. Со стороны основани  корпуса (за экраном) размещена свеча 6 и каналы 7 дл  отвода продуктов сгорани . Экран делит камеThe invention relates to engine-building, in particular to the structures of pre-chambers, mainly for rotary engines operating with flare ignition. Pre-chambers are known that contain a housing with channels for supplying air to and transporting combustion products, fuel supply nozzles, spark plugs. In these prechamber fuel injection to the chamber walls creates unfavorable conditions for the organization of a uniform air-fuel mixture, which reduces the completeness of fuel combustion. Prechamber chambers for internal combustion engines are also known, which include an air passage with channels for supplying air and exhausting combustion products, a fuel injection nozzle, a spark plug and a heat shield located between the nozzle and the candle 2. Disadvantages of known prechamber. are the cleaning of the volume of the chamber around the spark plug electrodes with a drain screen, and the heterogeneity of the layers of heavy air mixture caused by the rotational movement of the charge in the prechamber, which leads to the depletion of the e-cesi in the area of candles and, as a result, reduce the completeness of the combustion of fuel. The purpose of the invention is to increase the completeness of the combustion of fuel. This goal is achieved by the fact that the heat shield is made in the form of a hollow cone placed with a gap relative to the walls of the chamber of the pre-chamber, from the top of which the nozzle and tangentially channels for supplying air are coaxial with it, and from the base side the spark plug and the product outlet burnout Figure 1 shows the prechamber; in fig. 2 is a section A-A in FIG. 1. The prechamber contains housing 1, top covered with a lid 2. 3 of the working cavity of the chamber. There is a heat shield 3, made in the form of a hollow cone. The nozzle 4 is located coaxially with the screen in the top cover and here (in the cross-sectional plane AA) with a tangential exit to the working surface channels 5 are placed for supplying air. On the side of the base of the case (behind the screen) there is a candle 6 and channels 7 for the removal of combustion products. Screen divides the kame
