    Abstract: The present invention relates to a four-port valve capable of controlling directions of the flow of two types of fluid. This four-port valve is configured in such a manner as that: the inside of a casing 1 is divided into four chambers 3a, 3b, 3c and 3d by a substantially-X-shaped partition wall 2; two opposed chambers 3d and 3c are determined as fixing chambers communicating with ports respectively connected with two types of passages in which directions of the flow of fluid are fixed while the remaining two opposed chambers 3a and 3b are determined as change-over chambers communicating with ports respectively connected with two types of passages in which directions of the flow of fluid are alternately changed over; valve openings 5ac, 5ad, 5bd and 5bc for communicating two chambers adjacent to the substantially-X-shaped partition wall 2 with each other are provided; a valve plate 6 for closing the valve openings and a drive shaft 8 for supporting and oscillating the valve plate 6 are provided in one chamber while a valve plate 6' for closing the valve openings is provided to the opposed chamber 3c so that valve plate 6' is connected with the valve plate 6 supported by the drive shaft 8 by a semi-circular or circular connecting ring 7 piercing through the valve openings 5ac, 5ad, 5bd and 5bc.
