Aluminum piston used for anti-impact high-pressure piston accumulator

The utility model discloses an aluminum piston used for an anti-impact high-pressure piston accumulator. The aluminum piston comprises a piston body, a boss is arranged at the center of one end of the piston body, and a guide groove is arranged at the edge of the boss. The guide groove is arranged on the boss at the end of the piston body, the boss end at the end of the piston body is communicated with a hydraulic oil chamber so that the guide groove can buffer during operation, and accordingly impact of the piston body during operation is reduced, operation pressure of the accumulator can be increased, and service life of the accumulator can be prolonged.
