Beschreibung
Zusammenfassung:	The hydraulic rapid adjusting piston assembly comprises a piston and a valve plate fixed to the lower portion of the piston, the piston is provided with a pressurization channel and a pressure relief channel, the upper end of the pressurization channel and the upper end of the pressure relief channel are both located on the upper surface of the piston, and the lower end of the pressurization channel is located on the right side wall of the piston. The lower end of the pressure relief channel is located on the lower surface of the piston, the valve plate does not shield an opening in the lower end of the pressure relief channel, meanwhile, the upper portion of the piston is connected with a rotating plate in a pivoted mode, an arc-shaped groove is formed in the lower surface of the rotating plate, and the arc-shaped groove is matched with the upper end of the pressurization channel and the upper end of the pressure relief channel. The method has the advantage that the preparation and maintenance difficulty of
