A housing has an intake passage extending substantially in a vertical direction of a vehicle. A valve is configured to open and dose the intake passage. A shaft supports the valve. A bearing supports the shaft. A hose is connected with an upper side of the housing in the vertical direction and configured to lead intake air into the intake passage. A communication passage configured to communicate an inside of an internal combustion engine of the vehicle with the hose. The communication passage has an opening in the vicinity of a point directly above the bearing. The hose has a wall surface defining a condensate passage, which connects the opening with a target location from which condensate is to be dropped.

A fuel vapor treatment apparatus that includes a purge valve for controlling a quantity of fuel vapor purged from a canister. The apparatus also includes a controlling device that drives the purge valve based upon flow characteristic of the purge valve to a control amount for driving the purge valve to control a flow quantity of fluid flowing in the purge valve. The apparatus additionally includes a purge switching valve for switching communication of the purge valve between the canister and atmosphere. Furthermore, the apparatus includes a measuring device, which measures fluid pressure produced by opening the purge valve. The apparatus also includes a correcting device, which controls the purge switching valve and corrects the flow characteristic based upon pressure measured by the measuring device when the purge valve and the atmosphere communicate and based on the control amount in which the purge valve controlling device drives the purge valve.

Fuel vapor treatment apparatus

An electromagnetic valve device for reducing noise resulting from an internal collision of a movable core against a guide member has a fixed core, a cylindrical movable core, a valve member, for reciprocating in an axial direction of the movable core in a cooperative manner with the movable core to open and close fluid paths, coil sections for forming a magnetic field by electrical conduction thereof to attract the movable core to the fixed core so as to move the movable core in the axial direction, and a guide member having a guide wall for guiding the movable core in the axial direction from inside of the movable core in its radial direction. A space is formed inside the guide wall in its radial direction.

Electromagnetic valve device

A fluid controlling electromagnetic valve is formed by mechanically fixing one axial end portion of a stator core to an annular portion of a yoke, after the primary molding of a coil bobbin, and by sandwiching flanges of the coil bobbin having a coil wound by a predetermined number of turns around the outer circumference of a guide portion, between the rear end face of the annular portion of the yoke and front end face of an annular magnetic plate. A secondary molding is performed including a piece for regulating the axial moving distance of a valve member, to mold a housing of the fluid controlling electromagnetic valve.
