Abstract
A compressor includes: a cylinder defining a compression space, a piston structure accommodated in the cylinder and including a mount member and a guide member, the guide member being configured to reciprocate inside the compression space of the cylinder in an axial direction to compress a refrigerant gas therein and a magnet frame configured to support a mover, the mover being coupled to the piston structure and configured to move together with the piston structure. The mount member connects the guide member to the magnet frame and the guide member is configured to be rotated with respect to the mount member.
Claims19
A compressor comprising:
- a cylinder defining a compression space;
- a piston structure accommodated in the cylinder and including a mount member and a guide member, the guide member being configured to reciprocate inside the compression space of the cylinder in an axial direction to compress a refrigerant gas therein;
- and
- a magnet frame configured to support a mover, the mover being coupled to the piston structure and configured to move together with the piston structure,
- wherein the mount member connects the guide member to the magnet frame,
- wherein the guide member is configured to be rotated with respect to the mount member,
- wherein the piston structure includes a rotatable coupling member coupled to an inner circumferential surface of the guide member, and
- wherein the rotatable coupling member includes:
- a shaft member inserted into the rotatable coupling member, and
- a cutoff portion in the axial direction, the cutoff portion configured to be press-fitted to fix the rotatable coupling member to the inner circumferential surface of the guide member.
A compressor comprising:
- a cylinder defining a compression space;
- a piston structure accommodated in the cylinder and including a mount member and a guide member, the guide member being configured to reciprocate inside the compression space of the cylinder in an axial direction to compress a refrigerant gas therein;
- and
- a magnet frame configured to support a mover, the mover being coupled to the piston structure and configured to move together with the piston structure,
- wherein the mount member connects the guide member to the magnet frame,
- wherein the guide member is configured to be rotated with respect to the mount member,
- wherein the piston structure includes a rotatable coupling member coupled to an inner circumferential surface of the guide member,
- wherein the rotatable coupling member includes:
- a support portion supported inside the guide member, and
- a shaft member inserted into the support portion,
- wherein the mount member comprises:
- a joint portion rotatably coupled to the shaft member,
- a mount extension portion extending from the joint portion, and
- a mount coupling portion extending outward from one end of the mount extension portion in a radial direction, the mount coupling portion being connected to the magnet frame,
- wherein the joint portion is disposed at the support portion and defines a through-hole through which the shaft member is inserted, and
- wherein the shaft member passes through a central axis of the piston structure and is disposed at a center of gravity of the guide member to thereby reduce moment caused by eccentricity of the piston structure.
