Изобретение относитс  к уплотнительной технике, в частности ж Зплотвени м манжетного ти.па.The invention relates to a sealing technique, in particular to the sealing of a cuff.

Известны у1плотнительные манжеты, рабоча  ножка которых оперта иа жесткий олорный элемент дл  шредотвращени  ее выворачивани  под действием давлени  уплотн емой среды.Known sealing cuffs are known, the working leg of which is supported and a rigid olor element to prevent its turning under the action of the pressure of the sealing medium.

Однако какое-либо регулирование величины удельного давлени  на рабочей кромке манжеты лрактически не возможно.However, any adjustment of the specific pressure at the working edge of the cuff is not practical.

Цель изобретени  - ловысить долговечность уплотнени .The purpose of the invention is to catch the durability of the seal.

Это достигаетс  тем, что между рабочей ножкой манжеты и опорным элементом выполнена замкнута  камера, св занна  с источником управл ющего давлени .This is achieved by the fact that a chamber connected to a source of control pressure is closed between the working leg of the cuff and the supporting element.

На чертеже изображен один из возможных вариантов описываемого уплотнени .The drawing shows one of the possible variants of the described seal.

Рабоча  кромка / прижимаетс  к уплотн емому валу (на чертеже не токазан) пружиной 2 и силами упругости материала манжеты .The working edge / is pressed against the sealed shaft (not shown in the drawing) by the spring 2 and the elastic forces of the cuff material.

Дл  Предотвращени  выворачивани  манжет , 1ПОД действием давлени  в уплотн емойIn order to prevent the cuffs from everting out, the pressure in the compacted

полости ее ножка 3 вместе с рабочей губкой 4 оперты на жесткий опорный элемент 5. Между ножкой 3 и элементом 5 выполнена замкнута  полость А, св занна  через отверстие ac источником управл ющего давлени  (на чертеже не показан).Its leg 3, together with the working sponge 4, is supported on a rigid support element 5. A cavity A is connected between the leg 3 and element 5 and is connected through an opening ac by a source of control pressure (not shown).

При повышении давлени  в уплотн емой .полости возрастает удельное давление на рабочей кромке, при этом в полость А нодаетс When the pressure in the compacted cavity increases, the specific pressure at the working edge increases;

более высокое давление, которое, воздейству  на поверхность Б  ожки 3, компенсирует в 13начительной мере действие давлени  уплотн емой полости и приводит к ослаблению прижати  рабочей кромки к валу, а следовательно , к снижению удельного давлени  на ней.the higher pressure, which, acting on the surface of the burner, compensates in a significant degree the pressure of the cavity being compressed and weakens the pressure of the working edge against the shaft, and consequently, decreases the specific pressure on it.

Предмет изобретени Subject invention

Уплотнительна  манжета, рабоча  ножка которой оперта «а жесткий опорный элемент, отличающа с  тем, что, с делью повышени  долговечности уплотнени , между ножкой и опорным элементом выполнена замкнута  камера , св -занна  с источником управл ющего давлени .A sealing cuff, the working leg of which is supported "and a rigid support element, characterized in that, in order to increase the durability of the seal, there is a closed chamber between the leg and the support element connected to the control pressure source.
