Abstract
Provided is a linear compressor. The linear compressor includes a piston, a cylinder, and a bearing inflow passage. The bearing inflow passage includes a first bearing inflow passage extending inward from an outer circumferential surface of the cylinder in the radial direction and a second bearing inflow passage extending from the first bearing inflow passage to an inner circumferential surface of the cylinder. The second bearing inflow passage extends from the inner circumferential surface of the cylinder in a circumferential direction.
Claims20
A linear compressor comprising:
- a cylinder that extends in an axial direction;
- a piston received in the cylinder and configured to reciprocate relative to the cylinder along the axial direction;
- and
- a bearing inflow passage that penetrates the cylinder and that is configured to supply refrigerant to the piston, the bearing inflow passage comprising a front bearing inflow passage and a rear bearing inflow passage that are spaced apart from each other in the axial direction,
- wherein each of the front bearing inflow passage and the rear bearing inflow passage comprises a plurality of arc bearing inflow passages that are spaced apart from each other in a circumferential direction of the cylinder,
- wherein an arc bearing inflow passage among the plurality of arc bearing inflow passages extends from a portion of an inner circumferential surface of the cylinder along the circumferential direction in both sides with respect to a center of the arc bearing inflow passage, and
- wherein a cross-sectional area of the arc bearing inflow passage decreases along the circumferential direction as the arc bearing inflow passage extends away from the center of the arc bearing inflow passage.
