ABSTRACT:
A four-way valve for reversible refrigeration cycle. It comprises a casing, a delivery tube in communication with a compressor and opening into the casing, a suction tube in communication with the compressor and opening into the casing, a pair of tubes in communication with two heat exchangers respectively, and opening into the casing one on each side of the suction tube, valve means for communicating the suction tube selectively with either one of the pair of tubes; and a two-way pilot valve mounted longitudinally to the casing. The two-way valve longitudinally mounted to the valve body of the reversible valve permits its vertical installment, thus remarkably reducing horizontal space required therefor.
