Abstract: A by-pass mechanism including a door formed as a segment of a cylinder and mounted for swinging motion to alternate fluid flow control positions. A power element responsive to a changing condition of the controlled fluid is arranged for direct actuation of the door, with mechanical advantage. The door, and a mounting frame therefor, are constructed to impose minimal resistance to movement of the door in its travel to and from the alternate positions.
