Abstract
A reciprocating compressor is disclosed. The reciprocating compressor includes a shell, a driving motor, a driving shaft, a piston, a cylinder, and a suction muffler, and the suction flow path may include a valley portion formed as a cross-section area of the suction flow path becomes small. Accordingly, the structure of the suction muffler is simplified, thereby saving manufacturing cost of the suction muffler, a noise-reducing space is sufficiently secured while simplifying the structure of the suction muffler, thereby effectively reducing vibration and/or noise in the suction muffler, and the vibration and/or noise in the suction muffler can be more effectively reduced using the valley portion.
Claims20
A reciprocating compressor comprising:
- a shell;
- a driving motor arranged in an internal space of the shell;
- a driving shaft coupled to a rotor of the driving motor;
- a piston coupled to the driving shaft to reciprocate;
- a cylinder having the piston reciprocatably inserted thereinto to form a compression chamber together with the piston;
- and
- a suction muffler comprising a muffler entrance opening toward the internal space of the shell, a muffler exit opening toward a suction side of the compression chamber, a noise-reducing space located between the muffler entrance and the muffler exit, and a suction flow path connecting between the muffler entrance and the muffler exit with the noise-reducing space interposed therebetween,
- wherein the suction flow path comprises a valley portion formed as a cross-section area of the suction flow path becomes small.
