Abstract

1. Уплотнение подвижного вала гидравлической машины, содержащее корпус с крышкой, в котором установлена полая эластичная оболочка, выполненная с разъемом на одном торце для заполнения жидкостью и охватывающая вал, отличающееся тем, что оно снабжено цилиндром с установленным в нем дифференциальным поршнем, причем полость цилиндра под поршнем меньшей площади сообщена с полостью эластичной оболочки, а полость образованная частью поршня с большей площадью - с полостью цилиндра насоса, причем обе полости заполнены жидкостью, и снабжено емкостью с поршнем со штоком, заполненной уплотнительной жидкостью. ! 2. Уплотнение подвижного вала гидравлической машины по п.1, отличающееся тем, что в разъем эластичной оболочки вставлен ниппель, сообщающийся с полостью образованной поршнем с меньшей площадью, а в цилиндре в полости над поршнем с большей площадью, выполнено отверстие, снабженное эластичной диафрагмой, поджимаемой обоймой и сообщающееся с полостью цилиндра насоса. ! 3. Уплотнение подвижного вала гидравлической машины, содержащее корпус с крышкой, внутри которого образована герметичная камера для заполнения жидкостью и охватывающая вал, отличающееся тем, что оно снабжено цилиндром с установленным в нем дифференциальным поршнем, причем полость цилиндра под поршнем меньшей площади сообщена с полостью герметичной камеры, а полость образованная частью поршня с большей площадью - с полостью цилиндра насоса, обе полости заполнены жидкостью, и снабжено емкостью с поршнем со штоком, заполненной уплотнительной жидкостью, причем с торцов герметичной камеры установлены эластичные прокладки. ! 4. Уплотнение подвижного 1. The seal of the movable shaft of the hydraulic machine, comprising a housing with a cover, in which a hollow elastic shell is installed, made with a connector on one end for filling with liquid and covering the shaft, characterized in that it is equipped with a cylinder with a differential piston installed in it, and the cylinder cavity under the piston of a smaller area, it communicates with the cavity of the elastic shell, and the cavity formed by the part of the piston with a larger area communicates with the cavity of the pump cylinder, both cavities are filled with liquid and equipped with a capacitor a thaw with a piston with a stem filled with sealing fluid. ! 2. The sealing of the movable shaft of the hydraulic machine according to claim 1, characterized in that a nipple is inserted into the connector of the elastic shell communicating with the cavity formed by the piston with a smaller area, and a hole provided with an elastic diaphragm is made in the cylinder in the cavity above the piston with a larger area, compressible clip and communicating with the cavity of the pump cylinder. ! 3. The sealing of the movable shaft of the hydraulic machine, comprising a housing with a cover, inside which a sealed chamber for filling with liquid is formed and covering the shaft, characterized in that it is equipped with a cylinder with a differential piston installed in it, and the cylinder cavity under the piston of a smaller area communicates with the cavity chamber, and the cavity formed by the part of the piston with a larger area - with the cavity of the pump cylinder, both cavities are filled with liquid, and equipped with a container with a piston with a rod filled with a seal liquid, and elastic gaskets are installed from the ends of the sealed chamber. ! 4. Rolling seal
