摘要： A five-port switch valve includes a cylinder having five chambers defined by four partitions, and two actuators. The valve body of one actuator alternately opens and closes a hole formed in the partition and a hole formed in the partition. The valve body of the other actuator alternately opens and closes a hole formed in the partition and a hole formed in the partition. By virtue of this structure, brine fed into the central chamber through a port is alternately fed into two pressure converters through ports.
