Beschreibung
Zusammenfassung:	The invention provides a servo digital hydraulic oil cylinder. Comprising a cylinder barrel, a rear end cover, a servo motor, a front end cover, a piston rod and a shaft sleeve, wherein the rear end cover is fixedly mounted on one side of the cylinder barrel; the servo motor is fixedly mounted on one side of the rear end cover through a connecting sleeve; the front end cover is fixedly mounted on the other side of the cylinder barrel; the first oil pipe is communicated with the cylinder barrel and the interior of the bottom of the rear end cover. According to the servo digital hydraulic oil cylinder, the sealing section extends out of the rear end cover, so that when high-pressure hydraulic oil enters the left side of the cylinder barrel through the second oil pipe, the stress area of the hydraulic oil acting on the side face of the sealing section is small, and the generated acting force is relatively small; therefore, the piston rod is not prone to instantaneous stagnation in the rightward moving process, r
