To provide a rotary type selector valve capable of precluding effectively a periodic change in flow generated in association with the rotation of a valve element.
The arrangement of the rotary type selector valve has a common flow passage hole 12s provided nearer the common side opening 38 of an internal flow passage 28 and a selective flow passage hole 16 in communication confronting to the select side opening 35 of the internal flow passage 28, and when the common side opening 38 moves in association with the rotation of the valve element 11 and approaches the common flow passage hole 12s, an operating condition is generated which gives a fluid passing resistance to the fluid path between the select flow passage opening 16 and the common flow passage hole 12s, and when the common side opening 38 of the internal flow passage 28 moves in association with the rotation of the valve element 11 and has separated farther from the common flow passage hole 12s, a resistance adjusting means X generates the disengage condition in which the given resistance is released.
