摘要： A valve unit includes a housing which has a partition wall in which an opening portion is formed, a float valve which is disposed within a valve chamber R1 thereof, and a check valve which is disposed within a valve chamber R2. A valve seat is provided on a lower surface side of the partition wall, and plural radially-extending thin ribs are formed therearound. Plural axially-extending check valve guide ribs are provided at predetermined circumferential intervals with in the vent chamber R2, and plural axially-extending float valve guide ribs are provided at predetermined circumferential intervals within the valve chamber R1. The thin ribs and the check valve guide ribs are formed circumferentially alternately so as not to be superposed on each other when viewed from an axial direction of the housing.

摘要： There is provided a valve device including: a housing; a float valve; and a pressure adjusting valve. A first valve seat is formed from a peripheral edge of a valve hole. An accommodation portion is provided in a protruding manner from a surface of a partition wall. An inner periphery of the accommodation portion is provided with a reduced diameter portion and an increased diameter portion. A height of an upper end of the reduced diameter portion is equal to or greater than a front surface of the pressure adjusting valve in a state where the pressure adjusting valve is in contact with the first valve seat. The pressure adjusting valve is configured to be beyond the upper end of the reduced diameter portion when the pressure adjusting valve is raised to a maximum due to an increase in pressure in a fuel tank.

摘要： There is provided a valve device for a fuel tank. A housing is provided with a valve chamber and a vent chamber defined via a partition wall. The partition wall is provided with an opening. A float valve is received in the valve chamber to be movable up and down. The float valve includes a lower member and an upper member. The upper member includes a top portion, an outside wall extending from the top portion, and an elastic engaging piece configured to engage with an engaged portion of the lower member. The elastic engaging piece extends from a location on the back surface of the top portion, which is located inward from the outside wall, and is configured to elastically return after being bent in an outward radial direction of the upper member and thus to engage with the engaged portion of the lower member.
