Abstract

A refrigerator includes a valve assembly located at a refrigerant path from a condenser to at least one expansion valve for controlling flow of a refrigerant from the condenser to the at least one expansion valve. The valve assembly includes a valve chamber, wherein the refrigerant drawn from the condenser is held in the valve chamber; at least one outlet hole through which the refrigerant held in the valve chamber is discharged to a corresponding outlet path connected to the at least one expansion valve; and a valve body for selectively opening and closing the at least one outlet hole as the valve body rotates, such that the refrigerant held in the valve chamber is selectively discharged to the corresponding outlet path.
