WIPO Patent Application WO/2017/130598

A1

A rotary valve body (24) has a first passage (32a), and changes the state of communication between the first passage and a second passage (37a). A housing (25) has: said second passage; and a valve chamber (35) that houses the valve body and into which the second passage opens. A seal member (26a) is held by being compressed between the outer surface (39) of the valve body and an inner wall surface (40) forming the valve chamber, has a third passage (45a), and prevents leakage between the valve chamber and the first passage, the second passage, and the third passage. The seal member is pressed in contact with the outer surface of the valve body and the inner wall surface of the valve chamber respectively at a peripheral edge (52) of an opening (50) on one side of the third passage and a peripheral edge (53) of an opening (51) on the other side. The peripheral edge of the opening on one side is arranged in a rotation path of an opening (43a) of the first passage. The peripheral edge of the opening on the other side surrounds an opening (41a) of the second passage. The diameter of the third passage is the greatest at either the opening on one side or the opening on the other side.
