HYDRAULIC CYLINDER WITH DOUBLE-SIDE ROD Russian patent published in 2000 - IPC

FIELD: shipbuilding, mechanical engineering and other industries. SUBSTANCE: invention relates to lifting and transportation facilities. It is aimed at creating power double-action displacement hydraulic motors with rectilinear reciprocation of output member. Hydraulic cylinder has double-side rod coupled with piston and installed in hydraulic cylinder housing which is made with cylindrical end face necks. Rod can extended outwards from both sides of housing. Length of one of housing end face necks is not less than hydraulic cylinder travel value. Diameter of rod parts at different sides of piston can be either different or equal. EFFECT: prevention of corrosion, salt layer or fouling on rod side outer surfaces with piston in retracted position at operation of hydraulic cylinder in aggressive sea water. 3 cl, 2 dwg
