Abstract

A linear compressor is provided. The linear compressor may include a shell having a cylindrical shape, a shell cover that covers both open ends of the shell, a cylinder accommodated into the shell and defining a compression space for a refrigerant, a piston that reciprocates within the cylinder in an axial direction to compress the refrigerant within the compression space, a motor assembly including a motor that provides power to the piston and a stator cover that supports the motor, and resonant springs seated on the stator cover that support the piston to allow the piston to perform a resonant motion. The resonant springs may be circularly arranged at three points having a same interval around a center in an axial direction.

Dependent claims

A linear compressor, comprising:

a cylindrical shell extending from a first end to a second end opposite to the first end, the first and second ends being open, the cylindrical shell having a constant diameter along a length thereof from the first end to the second end;
a first shell cover coupled to the shell to cover the first end;
a second shell cover coupled to the shell to cover the second end;
a compressor body provided in the shell to compress a refrigerant, the compressor body having a first end and a second end opposite to the first end;
a first support directly coupled to a center of the first shell cover to support the first end of the compressor body, the first support being spaced apart from the shell;
and
a second support coupled to an inner circumferential surface the shell to support the second end of the compressor body.
