Estimating the term…
A method of packing elongated porous bodies moved between zones of different pressure, wherein the porous body (T) reciprocates through a pressurized packing agent (M). The packing agent is thixotropic and is supplied continuously to the porous cable (T) under a pressure exceeding the pressure in a higher pressure zone (P.sub.1) while the porous body (T) is impregnated with a thixotropic packing agent (M) such that the cross-section of the cable, throughout its entire length, is filled with packing agent (M). A hydraulic cylinder-type actuator utilizes a porous cable power transmission element packed in a chamber (7) filled with viscoelastoplastic material and communicated with means designed to develop in said chamber a pressure exceeding the pressure of the actuator working fluid.
A method of packing long-sized porous bodies moved between zones of different pressure, wherein the porous body (T) is moved between zones of different pressure, and is passed through a pressurized thixotropic packing agent (M) between the zones, characterized in that the packing agent (M) is a sealing compound with viscoelastoplastic properties having the following composition (mass percent):
A hydraulic cylinder with a flexible piston rod comprising a housing (3) with a work space (4) filled with a pressurized working fluid, said space accommodating therein a piston (5) coupled to a flexible rod (2) in the form of a rope and provided with at least one space packing assembly (6) having a chamber (7) filled with a viscous material, through which chamber is passed the flexible rod, characterized in that the viscous material is a viscoelastoplastic material and the chamber (7) of the packing assembly (6) is formed between two packing members (8, 9) positioned in the space of the housing (3), the chamber being coupled to means (10) for maintaining in said chamber a pressure exceeding the pressure of the working fluid in the work space (4) of the housing (3) irrespective of fluctuations in the pressure of the working fluid.
