Method for filling and emptying a hydraulic actuator working chamber and the hydraulic actuator together with the control system, and the hydraulic actuator for the execution of the method according to the invention

摘要

Method of filling and emptying the working chamber of the hydraulic fitter intended for a versatile application in industrial practice, in particular in the heavy industry and specially designed for use in systems operating at elevated temperature or under high workload conditions, the hydraulic fluid is delivered to each working chamber (6,7) of the hydraulic fitter by means of a valve (12a,12b),the hydraulic supply line (8, 9) and is discharged through the valve (12c, 12d) second,a plumbing line (10, 11). Hydraulic power train with cylinder control system (1),where the diver is installed or the pressure (4) piston (3) is combined is characterised by two being carried to each working chamber (6, 7) of the fitter, each equipped with a valve (12a, 12b, 12c, 12d),hydraulic lines, one of which is a hydraulic supply line (8, 9),and the second hydraulic line (10, 11). Hydraulic power train constructed from cylinder (1),where a diver or pressure (4) piston (3) is installed, each of the workrooms (6, 7) of the fitter shall be equipped with two short attachments, the first being intended to connect the hydraulic supply line and the second to connect the hydraulic supply line.
