A METHOD OF PACKING LONG-SIZED POROUS BODIES AND A HYDRAULIC CYLINDER UTILIZING SAME A b s t r a c t o f the D i s c l o s u r e The method of packing long-sized porous bodies moved between zones of different pressure, wherein the porous body moved between zones of different pressure reciprocates through a pressurized packing agent. The packing agent is an agent possessing thixotropic properties and supplied continuously to the porous body under pressure exceeding the pressure in a higher pressure zone while the porous body is impregnated with a thixotropic packing agent such that the cross-section of the porous body throughout the entire length thereof be filled with packing agent. The hydraulic cylinder utilizing said method comprises a chamber filled with a viscoelastoplastic material and communicated with means designed to develop in said chamber a pressure exceeding the pressure of the working fluid in the space of the hydraulic cylinder housing.
