Three-way valve and oxygen concentrator

Abstract

A three-way valve includes a manifold, a valve body, and a switching mechanism. The manifold is provided with a flow path including first, second and third ports, first, second and third passages leading to the first, second and third ports, and a valve chamber that communicates with the first, second, and third passages. The valve body is accommodated in the valve chamber and is displaceable to a first position at which the first port and the third port communicate with each other or a second position at which the second port and the third port communicate with each other. The switching mechanism switches a position of the valve body to the first position or the second position. The manifold is configured by a plurality of manifold members that have a plate shape and are stacked in a plate thickness direction.
