Abstract: A linear compressor, a shell for a linear compressor, and a method for manufacturing a shell of a linear compressor are provided. The shell may have at least one portion having a multilayer plate, in which at least two plates may be stacked in a direction substantially perpendicular to an axis of a piston so as to accommodate a cylinder, the piston, which may be reciprocated within the cylinder, and a motor assembly directly connected to the piston to provide a drive force to the piston. At least one resonator may be disposed in or at at least a portion of an inner surface of the shell.

Abstract: A linear compressor is provided. The linear compressor may include a cylinder that defines a compression space, a piston having a plurality of suction holes through which a refrigerant is introduced into the compression space, and a muffler connected to the piston and through which the refrigerant supplied to the piston flows. The muffler may include a seat seated on one side of the piston, and a protrusion arranged inside the piston. The protrusion may include plurality of flow pipes that extends from the seat to an inside of the piston to guide the refrigerant to the plurality of suction holes and a resonator arranged at one side of the plurality of flow pipes and having a resonance space therein.

Abstract: A linear compressor includes a cylinder that defines a compression space for a refrigerant, a frame that fixes the cylinder to a shell, a piston that axially reciprocates in an interior of the cylinder, a discharge valve that is provided in front of the cylinder to selectively discharge the refrigerator compressed in the compression space for the refrigerant, a discharge cover that is coupled to the frame and has a discharge space for the refrigerant discharged through the discharge valve, a valve spring that provides an axial resilient force to the discharge valve while supporting the discharge valve, and a valve support device that is coupled to the valve spring and supported by the frame to deliver vibration generated by the discharge valve to the frame.

Abstract: A reciprocating compressor is provided that may include a shell including a vibration absorbing member formed to be wound around an outer circumferential surface or an inner circumferential surface or stacked thereon, so that compressor vibration may be attenuated by frictional contact between the shell and the vibration absorbing member or between layers of the vibration absorbing member. Also a noise insulating layer may be formed between the shell and the vibration absorbing member or between the layers of the vibration absorbing member, so that a magnitude of noise may be reduced as vibration noise passes through the noise insulating layer, whereby vibration noise of the compressor, such as noise of a high frequency band, may be further attenuated by fine vibration.

Abstract: An linear compressor and a linear motor for a linear compressor is provided. The linear compressor may include a shell, in which a suction inlet may be provided, a cylinder disposed in the shell to define a compression space for a refrigerant, a frame coupled to an outer side of the cylinder, a piston reciprocated in an axial direction within the cylinder, a stator cover coupled to the frame, and a linear motor supported by the frame and the stator cover to provide power to the piston. The stator cover may include a body, and at least one frame coupling portion coupled to the frame. The at least one frame coupling portion may extend from the body toward the frame.
