Abstract
A valve device has a valve housing, a valve member, a guide member and a valve control unit. A center axis of a vapor outlet pipe is defined as a passage axis of a vapor outlet passage. A cross section of the vapor outlet pipe on a plane perpendicular to an axial direction of the vapor outlet pipe is defined as an outlet-pipe cross section. An area of the outlet-pipe cross section is defined as an outlet passage area. An overlapping area, in which the outlet-pipe cross section overlaps with an outlet-nearest wall portion, is formed when viewed them in the axial direction of the vapor outlet pipe and when the outlet-pipe cross section is projected on the outlet-nearest wall portion. The valve housing and the guide member are so formed that the overlapping area is smaller than a half of the outlet passage area.
