A muffler for a compressor and a compressor having the same are provided, in which a suction noise device and a discharge noise device may be integrally formed to reduce a number of components of a suction side muffler and a discharge side muffler so as to reduce leakage of refrigerant generated at an assembled portion of the muffler, and to reduce a length of a suction passage and a discharge passage. Such a division between the suction noise device and the discharge noise device may prevent discharged refrigerant from unintentionally heating suctioned refrigerant, which may reduce suction loss. The formation of the suction and discharge noise devices using a plastic material may reduce fabricating costs, and the structures of the suction and discharge side noise spaces may be simplified and noise removal effects may be improved, reducing an overall size of the muffler and improving noise effects. |

1. A muffler for a compressor, the muffler communicating with a compression chamber having a suction opening, which is opened and closed by a suction valve of a valve assembly, and a discharge opening, which is opened and closed by a discharge valve of the valve assembly, formed therein and being coupled to the valve assembly of a compression portion, the muffler comprising: a suction noise portion including a suction side noise space in communication with the suction opening of the compression chamber; a discharge noise portion including a discharge side noise space in communication with the discharge opening of the compression chamber; and a connection-fixing portion that integrally connects the suction noise portion and the discharge noise portion to each other, wherein a portion of the suction noise portion and a portion of the discharge noise portion are integrally formed as a one-piece component having at a suction side and a discharge side a connection housing, of the connection-fixing portion coupled to the valve assembly of the compression portion, wherein an internal pressure strength of a material of the discharge noise portion is greater than an internal pressure strength of a material of the suction noise portion, wherein the suction noise portion includes a suction side upper housing and a suction side lower housing coupled to a lower end of the suction side upper housing so as to form the suction side noise space therebetween, wherein the discharge noise portion includes a discharge side upper housing and a discharge side lower housing such that the discharge side upper housing is coupled to the discharge side lower housing so as to form the discharge side noise space therebetween, wherein the suction side upper housing and the discharge side upper housing are integrally formed with two opposite sides of the connection housing of the connection-fixing portion coupled to the compression portion and wherein an internal pressure strength of materials of the suction side upper housing, the discharge side upper housing, and the connection housing are greater than an internal pressure strength of a material of the suction side lower housing and the discharge side lower housing. |
