Изобретение относитс  к машиностроению , в частности к ротационным компрессорам .The invention relates to mechanical engineering, in particular to rotary compressors.

Цель изобретени  - повышение КПД путем уменьшени  мертвого объема и удельного давлени  в паре ротор-пластина.The purpose of the invention is to increase the efficiency by reducing the dead volume and the specific pressure in the rotor-plate pair.

Ротационный компрессор помещен под слоем рабочей смаэывающе-охлаждающей жидкости в герметичный кожух 1, в котором поддерживаетс  давление нагнетани . Компрессор содержит корпус 2, вертикальный вал 3 с эксцентриком 4, ротор 5, разделительную пластину 6, прижимаемую пружиной 7 к ротору 5. В разделительной пластине 6 со стороны ротора 5 имеетс  профилированна  по радиусу ротора 5 уплотни- тельна  цилиндрическа  вставка 8 с углом контакта ротора 5 с профилированным участком вставки 8, равным вот, и ограничитель углового перемещени  вставки 8 (винт 9) дл  предотвращени  проворачивани  профилированной цилиндрической вставки 8 вокруг ее продольной оси. В корпусе выполнены каналы подвода 10 и отвода 11 рабочей среды.A rotary compressor is placed under a layer of working coolant in a hermetic casing 1, in which the discharge pressure is maintained. The compressor includes a housing 2, a vertical shaft 3 with an eccentric 4, a rotor 5, a dividing plate 6 pressed by a spring 7 to the rotor 5. In the dividing plate 6 from the side of the rotor 5 there is a cylindrical insert 8 with a radially shaped rotor 5 with a contact angle 5 with a profiled portion of the insert 8, which is now equal, and a limiter of the angular displacement of the insert 8 (screw 9) to prevent the profiled cylindrical insert 8 from turning around its longitudinal axis. In the case, the supply channels 10 and outlet 11 of the working medium are made.

Компрессор работает следующим образом .The compressor works as follows.

При вращении вала 3 и ротора 5 происходит сжатие газа. При этом разделительна  пластина 6 под действием упругих сил пружины 7 и давлени  нагнетани  в кожухе 1 компрессора прижимаетс  к ротору 5 профилированным участком цилиндрической вставки 8. Рабочий газ сжимаетс  и вытесн етс  через канал 11 отвода. Удельное давление Ро и мертвый объем VM имеют оптимальную величину, определ емую углом контакта ротора 5 с цилиндрической вставкой 8 вот.When the shaft 3 and the rotor 5 rotate, the gas is compressed. In this case, the separator plate 6 under the action of the elastic forces of the spring 7 and the discharge pressure in the compressor housing 1 is pressed against the rotor 5 by the profiled section of the cylindrical insert 8. The working gas is compressed and expelled through the discharge channel 11. Specific pressure Po and dead volume VM have an optimum value determined by the contact angle of the rotor 5 with the cylindrical insert 8 here.
