Технической задачей, решаемой изобретением, является упрощение конструкции за счет обеспечения сообщения рабочей камеры с выхлопной камерой посредством выемки, выполненной в роторе.The technical problem solved by the invention is to simplify the design by ensuring communication of the working chamber with the exhaust chamber by means of a recess made in the rotor.

Для ее решения в роторном двигателе внутреннего сгорания, включающем полый корпус, цилиндрический ротор с поршнем, затвор с приводом управления затвором, камеру сгорания, снабженную устройством для подачи и сжигания топлива, рабочую камеру, образованную стенками затвора, поршня и корпуса, выхлопную камеру, образованную другими стенками затвора, поршня и корпуса, выхлопное отверстие, согласно изобретению рабочая камера выполнена сообщающейся с выхлопной камерой посредством выемки, выполненной в роторе перед поршнем со стороны направления его вращения таким образом, чтобы обеспечить выравнивание давления в упомянутых камерах для открытия затвора в момент прохождения поршнем выхлопного отверстия.To solve it, in a rotary internal combustion engine including a hollow body, a cylindrical rotor with a piston, a shutter with a gate control actuator, a combustion chamber equipped with a device for supplying and burning fuel, a working chamber formed by the walls of the shutter, piston and housing, an exhaust chamber formed other walls of the shutter, piston and housing, the exhaust hole, according to the invention, the working chamber is made communicating with the exhaust chamber by means of a recess made in the rotor in front of the piston from the side directed its rotation in such a way as to ensure equalization of pressure in the said chambers to open the shutter at the moment the piston passes the exhaust outlet.

Изобретение иллюстрируется чертежом, на котором схематически изображен поперечный разрез двигателя. Роторный двигатель внутреннего сгорания включает полый корпус 1, цилиндрический ротор 2 с поршнем 3, установленный на оси 4, затвор 5 для запирания рабочей камеры 9, образованной стенками затвора 5, поршня 3 и корпуса 1, от выхлопной камеры 10, образованной другими стенками затвора 5, поршня 3 и корпуса 1. Двигатель снабжен выхлопным отверстием 7. Выход устройства для подачи и сжигания топлива 8 расположен в камере сгорания 6. Выемка 11 выполнена в роторе 2 перед поршнем 3 со стороны направления его вращения таким образом, чтобы обеспечить выравнивание давления в упомянутых камерах 9 и 10 в момент прохождения поршнем 3 выхлопного отверстия 7. Геометрические размеры двигателя и выемки определяются расчетом с учетом мощности двигателя, его назначения, условия обеспечения достаточно быстрого выравнивания давления в камерах и других параметров двигателя. Положение поршня и расположение выемки в начале рабочего цикла обозначены А, их положение в конце цикла обозначено Б.The invention is illustrated in the drawing, which schematically shows a cross section of an engine. The rotary internal combustion engine includes a hollow body 1, a cylindrical rotor 2 with a piston 3 mounted on the axis 4, a shutter 5 for locking the working chamber 9 formed by the walls of the shutter 5, the piston 3 and the housing 1, from the exhaust chamber 10 formed by other walls of the shutter 5 of the piston 3 and the housing 1. The engine is equipped with an exhaust opening 7. The output of the device for supplying and burning fuel 8 is located in the combustion chamber 6. The recess 11 is made in the rotor 2 in front of the piston 3 from the direction of rotation so as to ensure alignment the pressure in the said chambers 9 and 10 at the moment the piston 3 passes the exhaust outlet 7. The geometric dimensions of the engine and the recess are determined by taking into account the engine power, its purpose, the conditions for ensuring fairly rapid pressure equalization in the chambers, and other engine parameters. The position of the piston and the location of the recess at the beginning of the working cycle are indicated by A, their position at the end of the cycle is indicated by B.

После закрытия затвора 5 и прохождения поршнем 3 выхода из камеры сгорания 6 (положение А) образуется разрежение, подается топливо, жидкое или твердое, через устройство для подачи и сжигания топлива (не показано) и происходит его воспламенение и сгорание в камере сгорания 6. При этом образуется повышенное давление в рабочей камере 9, образованной стенками затвора 5, поршня 3 и корпуса 1, и поршень 3 приходит в движение. Выхлопное отверстие 7 открыто. При прохождении поршнем 3 выхлопного отверстия 7 газы из рабочей камеры 9 выходят в атмосферу. Для открытия затвора 5 необходимо уравнять давление в рабочей 9 и выхлопной камере 10, что происходит посредством выемки 11 в момент прохождения поршнем 3 выхлопного отверстия 7 (положение Б). После открытия затвора 5 поршень 3 приходит в первоначальное положение, затвор 5 закрывается. Цикл работы завершен.After the shutter 5 is closed and the piston 3 passes the exit from the combustion chamber 6 (position A), a vacuum forms, fuel, liquid or solid, is supplied through a device for feeding and burning fuel (not shown) and it ignites and burns in the combustion chamber 6. When this creates an increased pressure in the working chamber 9, formed by the walls of the shutter 5, the piston 3 and the housing 1, and the piston 3 is set in motion. Exhaust port 7 is open. When the piston 3 passes the exhaust opening 7, the gases from the working chamber 9 are released into the atmosphere. To open the shutter 5, it is necessary to equalize the pressure in the working 9 and exhaust chamber 10, which occurs through the recess 11 at the moment the piston 3 passes the exhaust opening 7 (position B). After opening the shutter 5, the piston 3 comes to its original position, the shutter 5 closes. The work cycle is completed.
