Abstract
A pilot valve for reliably moving a switching valve of a gas control valve. The pilot valve includes a bottomed cylinder-shaped valve body having an opening at one end, spools slidably accommodated in the valve body, and resilient members disposed at other ends of the spools opposite to the opening side to urge the spools toward the opening side. The valve body has at least three through-hole portions substantially equally spaced in a longitudinal direction. The spools allow communication between at least two mutually adjacent through-hole portions. The resilient members are configured to press the spools toward the opening side of the valve body in cooperation with a pressing device, thereby switching the spools from a state where the spools are positioned at a side of the valve body opposite to the opening side to a state where the spools are positioned at the opening side.
