Abstract
A linear compressor includes a frame including a frame body, a frame head that extends from a front end of the frame body, a flange groove defined in the frame head, and a body hole that passes through the frame body; a cylinder including a cylinder body inserted into the body hole, a cylinder flange, and a cylinder head provided on a front end of the cylinder flange; and a lock ring press-fitted to be coupled to the flange groove and provided in a space defined between the cylinder head and an inner circumferential surface of the flange groove.
Claims20
A linear compressor, comprising:
- a shell;
- a frame received in the shell, an outer surface of the frame being spaced apart from an inner surface of the shell;
- a cylinder inserted in an accommodation hole which passes through the frame;
- and
- lock ring, a portion of an outer surface of which is press-fitted into the accommodation hole of the frame,
- wherein an inner surface of the lock ring is configured to encircle a portion of an outer surface of the cylinder,
- wherein the outer surface of the cylinder facing the inner surface of the lock ring is spaced apart from the inner surface of the lock ring so as not to contact an entire inner surface of the lock ring.
A linear compressor, comprising:
- a shell;
- a frame received in the shell, an outer surface of the frame being spaced apart from an inner surface of the shell;
- a cylinder inserted in an accommodation hole which passes through the frame;
- and
- a lock ring, a portion of an outer surface of which is press-fitted into the accommodation hole of the frame, wherein an inner circumferential surface of the lock ring is configured to encircle a portion of an outer surface of the cylinder, wherein the frame includes:
- a frame body extending in a first direction;
- and
- a frame head extending in a second direction from a first end of the frame body, wherein the accommodation hole includes:
- a flange groove formed at a junction between the frame body and the frame head, the flange groove being configured to receive a first portion of the cylinder and having:
- a bottom part;
- and
- a side part vertically extending from an outer edge of the bottom part;
- and
- a body hole passing through the frame body to communicate with the flange groove and configured to receive a second portion of the cylinder, and wherein the cylinder includes:
- a cylinder body inserted into the body hole;
- a cylinder head received in the flange groove and having an outer diameter greater than an outer diameter of the cylinder body at a first end of the cylinder body;
- and
- a cylinder flange formed between the cylinder body and the cylinder head to be received in the flange groove and having an outer diameter greater than the outer diameter of the cylinder head.
