Distribution valve

A distribution valve, comprising:

• a valve main body, having a first outlet, a second outlet, and an inlet;
• a cylindrical valve body, rotatably fitted into the valve main body;
• and
• a driver, configured to rotate the valve body,
• wherein the valve body comprises a peripheral wall portion that functions as a sealing surface portion that closes the first outlet and the second outlet, and a bottom surface portion that functions as a sealing surface portion that closes the inlet,
• the peripheral wall portion is formed with a first opening portion and a second opening portion configured to continuously change an opening area of the first outlet and an opening area of the second outlet by rotation of the valve body,
• the bottom surface portion is formed with a third opening portion configured to change an opening area of the inlet within a predetermined range by rotation of the valve body, and
• the distribution valve distributes a fluid flowing into the valve body from the inlet to the first outlet and the second outlet, wherein
• a valve seat member provided with a seal portion that seals by contacting the bottom surface portion is arranged in the inlet, and
• the valve seat member is movable in an axial direction of the valve body, and is configured such that the seal portion adheres to the bottom surface portion as the valve seat member is pressed toward the valve body by a supply pressure of fluid acting on the inlet.
