Abstract
A two-stage switch valve includes a valve body slidable in a flow passage of a fluid, and a spring urging the valve body upstream. The valve body includes a valve element slidable in the flow passage, an upstream guide having a ring shape and being slidable in the flow passage, and legs connecting the valve element and the upstream guide. The upstream guide is located upstream of the valve element. The legs are inclined from an axial direction of the upstream guide and extend from the upstream guide toward a center of the valve element.
