Abstract
A vortex-type flow regulation valve includes: a vortex chamber having a cylinder-shaped circumferential side wall, a first end wall and a second end wall; an inlet flow passage that extends along an inlet flow passage center axis and opens in the circumferential side wall; an outlet flow passage that extends along an outlet flow passage center axis and opens into the first end wall; a protrusion protruding into the vortex chamber from one of the first end wall and the second end wall; and a driving unit that causes the protrusion to move toward and away from the other of the first end wall and the second end wall, within the vortex chamber. The inlet flow passage center axis passes through a location distanced from a vortex chamber center axis, and the movement of the protrusion regulates the flow rate of a fluid flowing out from the outlet flow passage.
