Abstract
A linear compressor is provided. The linear compressor may include a frame coupled to a cylinder, a gas hole defined in the frame, and a gas pocket that communicates with the gas hole and transfers a refrigerant gas to the cylinder.
Claims21
A linear compressor, comprising:
- a cylinder that defines a compression space for a refrigerant;
- a piston that reciprocates in an axial direction within the cylinder;
- a discharge valve provided at a front side of the cylinder to selectively discharge the refrigerant compressed in the compression space;
- a frame coupled to the cylinder and having a gas hole through which the refrigerant discharged through the discharge valve flows;
- a gas pocket provided between the cylinder and the frame and through which the refrigerant passing through the gas hole flows;
- and
- one or more gas inflow provided in the cylinder to introduce the refrigerant flowing through the gas pocket to an outer side of the piston.
4 more elements
The linear compressor according to clam 11, wherein the one or more gas inflow of the cylinder includes:
- a first gas inflow provided in a front portion of the cylinder;
- and
- a second gas inflow provided in a rear portion of the cylinder.
The linear compressor according to clam 13, wherein the discharge filter includes a plurality of filters.
A linear compressor comprising:
- a cylinder that defines a compression space for a refrigerant;
- a piston that reciprocates n an axial direction within the cylinder;
- a discharge valve provided to be operable and closable at one side of the cylinder;
- a frame coupled to the cylinder;
- a gas pocket formed between the cylinder and the frame and through which the refrigerant is introduced between the cylinder and the frame;
- and
- one or more gas inflow provided in the cylinder and through which the refrigerant in the gas pocket is introduced to an outer surface of the piston, wherein the frame includes a gas hole to allow the refrigerant discharged from the discharge valve to flow to the gas pocket.
