Muffler for compressor and compressor having the same

A compressor, comprising a casing;

• a cylinder block of a compression portion provided in the casing and having a compression chamber;
• a valve assembly of the compression portion installed on the cylinder block and having a suction opening and a discharge opening in communication with the compression chamber;
• and an integral muffler coupled to the valve assembly so as to be in communication with the compression chamber, the integral muffler including:
• a suction noise portion having a suction side noise space in communication with the suction opening of the valve assembly;
• a discharge noise portion having a discharge side noise space in communication with the discharge opening of the valve assembly;
• and
• a connection-fixing portion that integrally connects the suction noise portion and the discharge noise portion to each other and includes a connection housing, 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 of the connection housing, of the connection-fixing portion being 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 or the discharge side lower housing.
