A lever float valve comprising a float stem with a central vertical axis; a float body coupled to the float stem and rotatable relative to the central vertical axis of the float stem; a valve segment positioned within the float body and configured to pivot around a first axis perpendicular to the vertical axis; and a lever comprising a float arm and a float coupled to the valve segment and configured to pivot around a second axis perpendicular to the vertical axis.

The invention relates to a tank for receiving fuel, said tank comprising a venting system comprising a flap for closing an opening made in the tank, said flap being subjected to a float and mounted in a hinged manner in the tank so as to adopt a closed position, pushed by the float when the level of fuel in the tank reaches a certain threshold, and an open, venting position, driven by the float when the level of fuel is below said threshold. According to the invention, the flap comprises a valve controlled by means that can open the valve when the flap is in a closed position and the level of fuel is below said threshold.

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.

A fluid limit vent valve assembly includes a lower case having a base portion and an outer wall extending from the base portion to define a lower case interior cavity and an opening at an end of the lower case opposite the base portion. A first slot extends through the outer wall. A fuel flow diverter is positioned in the interior cavity directly opposite first slot and extends along a path between the first slot and a vapor exit passage of the valve assembly. The flow diverter prevents splashing of liquid fuel into a vapor exit passage of the valve assembly. A second slot also extends through the lower case outer wall and is angularly spaced apart from the first slot.

Provided is a roll over fuel-vapor valve is provided including a housing defining a valve having a valve inlet port extending through a wall of the housing and a valve outlet port and a float member disposed between the inlet port and the outlet port and being displaceable between an open position and a closed position the hosing further comprising a fluid flow channel extending along a top portion thereof and having a first end and a second end, wherein the outlet port extending into the channel such that in the open position fluid flow is facilitated between the valve inlet port and the channel.

A fuel storage device includes a fuel tank, a circulation passage, a canister, a vapor passage, and an adjuster. The fuel tank is configured to store fuel. The circulation passage fluidly connects the fuel tank and a vicinity of a fuel supply port. The canister is configured to recover gas generated in the fuel tank. The vapor passage fluidly connects the fuel tank and the canister. The adjuster is configured to adjust a circulation flow rate of the gas flowing through the circulation passage in supply of the fuel, using a negative pressure.

A fuel tank unit may include a fuel tank, a canister configured to adsorb and desorb vapor generated in the fuel tank, a vapor conduit communicating the fuel tank with the canister, and a full tank fuel level limiting valve device connected to a fuel tank-side end of the vapor conduit. The full tank fuel level limiting valve device includes a full tank fuel level limiting valve and an actuator. The full tank fuel level limiting valve includes a float that is configured to float due to a buoyancy force of fuel in the fuel tank so as to close the full tank fuel level limiting valve when the fuel tank is filled up. The actuator includes a valve closure prevention member that is configured to move and press the float when the actuator is activated, so as to prevent the float from moving in a valve closing direction.

An apparatus for preventing fuel overflow of a vehicle fuel tank includes: a valve unit including a valve body, a housing configured to cover a lower part of the valve body, a float mounted on the valve body and configured to slide up and down, a vapor line opened and closed according to a movement of the float, and a fuel inlet hole; a cover unit coupled to and enveloping the housing, the cover unit having a plurality of windows along an outer circumferential surface at a height corresponding to the fuel inlet hole, thereby being formed to allow the fuel to be introduced into the valve unit; and a shielding unit mounted on the cover unit to shield open windows, the shielding unit able to rotate along a turning direction of the vehicle to form an inflow path of the fuel flowing into the fuel inlet hole.

A fuel device assembly including a valve assembly and a baffle plate, the valve assembly including a valve cover and a first weld plate provided at an upper end of the valve cover coupling the valve assembly to an interior-facing surface a fuel tank of a vehicle, the baffle plate including a body having a plurality of spaced apart holes formed therein and a housing member extending from the body for receiving and lockingly engaging the valve assembly.

There is provided a fill-up restriction valve including: a housing; and a float valve. The housing includes a housing body including a body-side peripheral wall, and a lower cap including a cap-side peripheral wall, the lower cap being installed to a lower side of the housing body by a joint portion. The joint portion includes an annular groove, an insertion wall portion, and an annular protrusion formed on one of the insertion wall portion and the annular groove, or an annular seal member disposed between the insertion wall portion and the annular groove. The annular protrusion or the annular seal member is configured to be in pressure-contact with the annular groove and the insertion wall portion in a state where the insertion wall portion is inserted into the annular groove.
