Abstract
A linear compressor includes a shell, a motor in the shell, a mover coupled to the motor and configured to perform a reciprocating motion in an axial direction, a cylinder disposed in the shell, a piston coupled to the mover and configured to reciprocate in the cylinder, a spring that supports the piston in the axial direction, and a spring cap inserted into an end portion of the spring. The spring cap defines a space portion that is defined inside the spring cap and has a volume separate from the inner space of the shell, and a passage portion that extends through an axial side surface of the spring cap and is configured to provide communication between the space portion and the inner space of the shell.
Claims19
A linear compressor, comprising:
- a shell that defines an inner space therein;
- a motor disposed in the inner space of the shell, the motor comprising a mover configured to perform a reciprocating motion in an axial direction;
- a cylinder disposed in the inner space of the shell;
- a piston coupled to the mover of the motor and configured to reciprocate in the cylinder;
- a spring that supports the piston in the axial direction;
- a spring supporter coupled to the piston or the mover of the motor, the spring supporter defining a cap support hole;
- and
- a spring cap that is inserted into the cap support hole and supports an end portion of the spring,
- wherein the spring cap defines:
- a space portion that is defined inside the spring cap and has an interior volume, and
- a passage portion that extends through a first axial side surface of the spring cap and is configured to provide communication between the space portion and the inner space of the shell,
- wherein the spring cap comprises:
- a first cap inserted into a first side of the cap support hole, and
- a second cap inserted into a second side of the cap support hole opposite to the first side in the axial direction, and
- wherein the first cap and the second cap are in communication with each other through the cap support hole and define the space portion inside the first cap and the second cap.
