го соединени  на корпусе 2 и упираетс в крестовину 10. Сопло снабжено установленным внутри диффузора 3 конусом , il, к основанию которого при реплен один из отражательных дисков 7, причем этот диск выполнен с кольцевой выемкой 12 на рабочей поверх ности. Конус 11 соединен с диском 7 болтом 13. Корпус 2 соединен с материало проводом 4 с помощью хомута 14. Сопло работает следующим образом. Подготовленный в установке 1 материал , например бетонна  смесь, поступает под давлением по напорному материалопроводу 4 к соплу. Проход  через диффузор 3 корпуса 2, материал за сче конуса 11 поступает в зазор между дис ками 6 и 7 и через радиальную кольцевую щель 8 выбрасываетс  под давлением на внутреннюю поверхность тела вра щени , например, сердечник центрифуги рованной трубы. При осевом перемещении сопла материал равномерно наносит с  по всему внутреннему сечению изготавливаемого тела вращени . Можно последовательно наносить несколько слое Благодар  конусу, установленному внутри диффузора, повышаетс  надежность работы сопла и улучшаетс  качество наносимого сло  за счет более равномерного нанесени  сло  и образовани  более плотной его структуры. Кроме того, предлагаемое согшо поэ вол ет значительно повысить производительность за счет сокращени  цикла нанесени  материала на внутреннюю поверхность тела вращени . Формула изобретени  Сопло дл  нанесени  материала на внутреннюю поверхность тела вращени , содержащее соединенный с напорным материалопроводом корпус с диффузором и отражательными дисками, установленными с зазором, образующим радиальную кольцевую щель дл  прохода материала, отличающеес   тем, что, с целью повышени  надежности работы и улучшени  качества наносимого сло , сопло снабжено установленным внутри диффузора конусом, к основанию которого прикреплен один из отражательных дисков, причем последний выполнен с кольцевой выемкой на рабочей поверхности . Источники информации, прин тые во внимание при зкспертизе: 1.Справочник Машины, механизмы и оборудование дл  бетонных и железобетонных работ , м., Стройиздат, 1974, с. 209, рис. 110. The joint is mounted on the housing 2 and rests on the crosspiece 10. The nozzle is provided with a cone mounted inside the diffuser 3, il, to the base of which, when replenished, one of the reflective disks 7, and this disk is made with an annular recess 12 on the working surface. The cone 11 is connected to the disk 7 by a bolt 13. The case 2 is connected to the material by a wire 4 by means of a collar 14. The nozzle operates as follows. The material prepared in installation 1, for example, a concrete mixture, flows under pressure through a pressure material 4 to the nozzle. The passage through the diffuser 3 of the housing 2, the material beyond the cone 11 enters the gap between the disks 6 and 7 and through the radial annular slot 8 is ejected under pressure onto the inner surface of the rotational body, for example, the core of the centrifuged tube. When the nozzle is axially moved, the material evenly applies a rotation around the entire internal section of the body to be made. Multiple layers can be applied successively. Thanks to the cone installed inside the diffuser, the reliability of the nozzle operation is improved and the quality of the applied layer is improved due to a more even application of the layer and the formation of a more dense structure. In addition, the proposed technique significantly increases productivity by reducing the cycle of application of the material to the inner surface of the body of revolution. The invention includes a nozzle for applying material to the inner surface of a body of revolution, comprising a housing connected to a pressure material pipe with a diffuser and reflective discs installed with a gap forming a radial annular slot for material to pass through, in order to increase reliability and improve the quality of the applied layer, the nozzle is provided with a cone installed inside the diffuser, to the base of which one of the reflective disks is attached, the latter being made with an annular recess a working surface.
