Compressor

A scroll compressor, comprising:

• a casing comprising a rotational shaft;
• a discharge cover fixed inside of the casing to partition the inside of the casing into a suction space and a discharge space;
• a first scroll that is revolved by rotation of the rotational shaft;
• a second scroll that defines a plurality of compression chambers together with the first scroll, the second scroll having at least one bypass hole that communicates with at least one of the plurality of compression chambers and a discharge hole that discharges a compressed refrigerant;
• a valve coupled to the second scroll to open and close the at least one bypass hole;
• a stopper configured to restrict a moving distance of the valve when the valve opens and closes the at least one bypass hole;
• and
• a coupling member configured to couple the valve and the stopper to the second scroll, wherein a coupling hole through which the coupling member passes is defined in each of the valve and the stopper, wherein a coupling groove to which the coupling member is coupled is defined in the second scroll, wherein the coupling member comprises a rivet, wherein a screw thread or unevenness is formed on an inner circumferential surface of the coupling groove of the second scroll, and wherein the coupling member is engaged with the screw thread or unevenness formed on the inner circumferential surface of the coupling groove when the coupling member passes through the valve and is coupled to the coupling groove.

A compressor, comprising:

• a first member having at least one hole through which a fluid flows;
• a valve coupled to the first member to open and close the at least one hole;
• a rivet configured to couple the valve to the first member;
• and
• a second member coupled to the first member, the second member having an avoiding space to avoid the rivet and the valve, wherein, when the rivet is coupled to the first member, a coupling body of the rivet is engaged with a screw thread or unevenness formed on an inner circumferential surface of a coupling groove of the first member.
