Abstract
A reciprocating compressor is provided that may include a shell, a suction pipe coupled to the shell, a driver provided inside of the shell that generates a rotational force, a compression device including a connecting rod that converts the rotational force into a linear driving force, a piston coupled to the connecting rod, and a cylinder into which the piston is movably inserted, a suction muffler provided inside of the shell that reduces a pressure pulsation of a refrigerant suctioned through the suction pipe, and a suction guide that extends from the shell to the suction muffler and includes at least one protrusion that contacts an inner surface of the shell.
Claims18
A reciprocating compressor, comprising:
- a shell;
- a suction pipe coupled to the shell;
- a driver provided inside of the shell that generates a rotational force;
- a compression device including:
- a connecting rod that converts the rotational force into a linear driving force;
- a piston coupled to the connecting rod;
- and
- a cylinder into which the piston is movably inserted;
- a suction muffler provided inside of the shell that reduces a pressure pulsation of a refrigerant suctioned through the suction pipe;
- and
- a suction guide that extends from the shell to the suction muffler, the suction guide including:
- a guide body having a front surface that faces an inner surface of the shell, the front surface being spaced apart from the inner surface of the shell;
- a plurality of protrusions that protrudes from the front surface of the guide body and contacts the inner surface of the shell, the plurality of protrusions being spaced apart from each other;
- and
- a space defined by the front surface and the plurality of protrusions and through which the refrigerant suctioned through the suction pipe flows into the inside of the shell.
A reciprocating compressor, comprising:
- a shell;
- a suction pipe coupled to the shell;
- a driver provided inside of the shell that generates a rotational force;
- a compression device including:
- a connecting rod that converts the rotational force into a linear driving force;
- a piston coupled to the connecting rod;
- and
- a cylinder in which the piston is movably inserted;
- a suction muffler provided inside of the shell that transfers a refrigerant suctioned through the suction pipe to the cylinder;
- and
- a suction guide coupled to the suction muffler that transfers the refrigerant suctioned through the suction pipe to the suction muffler, wherein the suction guide device includes:
- a guide body including a front surface spaced apart from an inner surface of the shell;
- a plurality of protrusions provided between the front surface and the inner surface of the shell, the plurality of protrusions protruding from the front surface and contacting the front surface of the guide body;
- and
- a space defined by the front surface and the plurality of protrusions and through which the refrigerant suctioned through the suction pipe flows into the inside of the shell.
A reciprocating compressor, comprising:
- a first shell;
- a second shell that forms a closed space with the first shell;
- a suction pipe coupled to the first shell;
- a driver provided inside of the closed space that generates a rotational force;
- a compression device including:
- a connecting rod that converts the rotational force into a linear driving force;
- a piston coupled to the connecting rod;
- and
- a cylinder in which the piston is movably inserted;
- a suction muffler provided inside of the closed space that transfers a refrigerant suctioned through the suction pipe to the cylinder;
- and
- a suction guide coupled to the suction muffler that transfers the refrigerant suctioned through the suction pipe to the suction muffler, wherein the suction guide includes:
- a guide body including a front surface spaced apart from an inner surface of the first shell;
- a plurality of protrusions provided between the front surface and the inner surface of the first shell, the plurality of protrusions protruding from and contacting the front surface of the guide body;
- and
- a space defined by the front surface and the plurality of protrusions and through which the refrigerant suctioned through the suction pipe flows into the inside of the closed space.
