Abstract (en)
[origin: CN106286437A] The present invention discloses a hydraulic system which has a hydraulic cylinder (2) having at least three separated action surfaces (48, 50, 52) capable of loading pressure medium. The pressure medium can load the first action surface (48) and the second action surface (50) to allow the piston element/rod elements (12) of the hydraulic cylinder (2) to move at the outside direction. A storage sequence valve (42) is arranged to load the second action surface (50) on the outside direction (8) through the pressure medium of a loaded storage (38).
