Abstract

Изобретение может быть использовано в уплотнени х подвижных узлов гидравлических и пневматических устройств. Цель изобретени - повышение экономичности вибрационного уплотнени за счет снижени потребл емой мощности от источника питани . Пьезокерамическое кольцо (К) 8 установлено с возможностью деформации. Между К 8 и уплотн емой поверхностью размещен умножитель хода К 8, выполненный в виде установленной с нат гом,по уплотн емой поверхности упругой кольцевой скобы 4 трапециевидного профил . Умножитель обращен меньшим основанием к уплотн емой поверхности и жестко соединен с торцами К 8. Эластична прокладка 14 установлена на торцовой поверхности корпуса . Торцовые поверхности скобы 4 выполнены в виде бурта, взаимодействующего с прокладкой 14. Цилиндрический элемент 6 скобы 4 взаимодействует с устройством поджима, установленным со стороны высокого давлени . В скобе 4 в осевом направлении выполнены прорези 9. Полость между К 8 и скобой 4 и прорези 9 заполнены эластичным материалом. 2 ил.The invention can be used in seals of movable units of hydraulic and pneumatic devices. The purpose of the invention is to increase the efficiency of vibratory compaction by reducing the power consumption from the power source. The piezoceramic ring (K) 8 is installed with the possibility of deformation. Between K 8 and the surface to be compacted, there is a K 8 travel multiplier, made in the form of an elastic ring clip 4 of a trapezoidal profile installed with a tension on the sealing surface. The multiplier faces the smaller base to the sealing surface and is rigidly connected to the ends of the K 8. Elastic gasket 14 is installed on the end surface of the housing. The end surfaces of the bracket 4 are made in the form of a collar interacting with the gasket 14. The cylindrical element 6 of the bracket 4 cooperates with a pressing device mounted on the high pressure side. In the bracket 4 in the axial direction, the slots 9 are made. The cavity between the K 8 and the bracket 4 and the slots 9 are filled with an elastic material. 2 Il.
