Abstract
A piston assembly for a compressor assembly is provided. The piston assembly has a piston and a valve sheet. The valve sheet is arranged at an end of the piston. The valve sheet has a valve sheet body with a mounting port, and a valve tongue connected to the valve sheet body. At least part of the valve tongue is arranged in the mounting port. At least part of a contour of the mounting port matches with a circumferential contour of one end of the piston close to the valve sheet.
Claims7
A piston assembly comprising:
- a piston;
- and
- a valve sheet arranged at one end of the piston closer to the valve sheet, wherein the valve sheet comprises:
- a valve sheet body defining a mounting port;
- and
- a valve tongue connected to the valve sheet body,
- wherein the one end of the piston closer to the valve sheet is provided with a cooperating groove, and a shape of the cooperating groove matches with a shape of the valve tongue,
- wherein the valve tongue comprises:
- a connecting portion connected to the valve sheet body;
- an extension portion arranged in the contour of the mounting port;
- and
- a connection portion configured to connect the connecting portion and the extension portion,
- wherein the extension portion is connected to the valve sheet body only through the connection portion and the connecting portion,
- wherein the valve tongue extends in an extending direction,
- wherein a part of the connecting portion is arranged in the mounting port,
- wherein a width of the connection portion along the extending direction is narrower than a width of the connecting portion along the extending direction and a width of the extension portion along the extending direction,
- wherein a contour of the mounting port is circular except where the part of the connecting portion that is arranged in the mounting port is provided,
- wherein a circumferential contour of the one end of the piston matches the contour of the mounting port, and
- wherein a spacer groove is formed between the connecting portion and the valve sheet body, and one end of the spacer groove away from the mounting port forms a processing hole, where the width of the connecting portion adjacent to the processing hole is smaller than a width of the connecting portion adjacent to the spacer groove.
