Abstract
A linear compressor is provided that may include a cylinder, to which a discharge valve may be coupled; a first piston, which may be provided to enable a reciprocating motion in an inside of the cylinder; a second piston, which may be provided to enable a reciprocating motion in an inside of the first piston; a first compression chamber formed between the discharge valve and the first piston; and a second compression chamber formed between the first piston and the second piston. The first piston and second piston may move in opposite directions with respect to each other.
Claims23
A linear compressor, comprising:
- a cylinder, to which a discharge valve is coupled;
- a first piston, which is provided to enable a reciprocating motion in an inside of the cylinder;
- a second piston, which is provided to enable a reciprocating motion in an inside of the first piston;
- a first compression chamber formed between the discharge valve and the first piston;
- and
- a second compression chamber formed between the first piston and the second piston, wherein the first piston and second piston move in opposite directions with respect to each other.
A linear compressor, comprising:
- a cylinder to which a discharge valve is coupled;
- a first piston, which is provided to enable a reciprocating motion in an inside of the cylinder;
- a second piston, which is provided to enable a reciprocating motion in an inside of the first piston;
- a first compression chamber formed between the discharge valve and the first piston;
- and
- a second compression chamber formed in the inside of the first piston, wherein a refrigerant of the second compression chamber is suctioned into the first compression chamber when the first piston moves in a first direction and the second piston moves in a second direction, and a refrigerant of the first compression chamber is discharged and suction of the refrigerant is performed into the second compression chamber when the first piston moves in the second direction and the second piston moves in the first direction.
A linear compressor, comprising:
- a cylinder;
- a plurality of pistons coaxially provided within the cylinder and forming a plurality of compression chambers within the cylinder, wherein the plurality of pistons is capable of moving in a same direction and opposite directions with respect to each other to perform in-phase and anti-phase behaviors with respect to one another while performing two stage compression of a refrigerant.
