A fuel shut-off valve includes a housing, a float valve, and a tubular fuel inflow portion. The housing includes a communicating opening that communicates with the outside of the fuel tank, a tubular portion that extends in a vertical direction, and an inlet for liquid fuel located in the tubular portion at a position below the communicating opening. The float valve selectively closes and opens the communicating opening by moving vertically. The fuel inflow portion is provided outside the tubular portion and has a first end having an inflow port for liquid fuel and a second end connected to the inlet. The inflow port is opened at a position that is above the inlet and spaced outward in a radial direction from the tubular portion. The housing includes a discharge port for discharging liquid fuel in the housing.

A fill limit vent valve includes a float valve, a housing, and a lid. The housing includes a cylindrical outer wall and a tubular portion. The outer wall has a central axis. The tubular portion accommodates the float valve. The lid is placed on the upper end of the tubular portion and has a communicating opening. The housing includes a fuel passage that has an inlet and a discharge port. The discharge port is connected to the communicating opening. A section of the tubular portion that faces the fuel passage is constituted by a curved surface. A guide wall that has at least one guide surface is provided between the fuel passage and the inlet. A straight line on the curved surface that is parallel with the central axis is defined as a generatrix. The guide surface extends along the curved surface while being inclined relative to the generatrix.

A valve assembly includes a housing having first and second body portions cooperating to enclose a cavity. The first body portion includes a cap having a nozzle that extends from the cap, and the nozzle defines an outlet. The first body portion includes a seat defining an orifice in fluid communication with the outlet and the cavity. A float is disposed inside the cavity. A seal is spaced from the seat when the float is in the initial position and the seal engages the seat when the float is in the displaced position. In certain configurations, the cap, the nozzle, and the seat are formed together as one piece. In certain configurations, a second side wall surrounds the float and extends across the window to obstruct direct fluid communication between the window and the float. A gap is unobstructed between a first side wall and the second side wall.

A casing 100 of fuel shutoff valve 10 includes a housing 120 having a partition part 122 with a communication hole 124, the partition part 122 dividing the inside of the casing into an upper space CU and a lower space CL, a check valve case 140 supporting a check valve structure 142, and a cutoff valve case 160 storing a float 162. The casing 100 includes a communication passage C10 connecting a space C16 storing the float 162 and a space C14 in the check valve case 140 and having a delivery opening 168 of the cutoff valve case, the communication hole 124, and a reception opening 146 of the check valve case. The reception opening 146 deviates relative to the delivery opening 168. The check valve case 140 includes an additional flow path part C142 allowing the circulation of fuel vapor, together with the communication hole.

There is provided a valve device for a fuel tank including: a housing; a first float valve accommodated in a first valve chamber; and a second float valve accommodated in a second valve chamber. The housing includes a housing body and a lower cap. The housing body has a housing body peripheral wall. The housing body peripheral wall has a first valve chamber forming wall that forms an outer periphery of the first valve chamber, and a second valve chamber forming wall that has a contour shape different from that of the first valve chamber forming wall and that forms an outer periphery of the second valve chamber. The lower cap has a cap peripheral wall having a shape fitting to the housing body peripheral wall.

The application relates to a fill level valve for a pressure equalization line of a fluid tank assembly, wherein the pressure equalization line is fluidically connected between a fluid tank and a filling line opening into the fluid tank, and wherein the fill level valve includes a connecting piece which can be arranged on the fluid tank. It is provided here that a dip tube, which can be arranged in the fluid tank, and which is fluidically connected to the connecting piece, originates from the connecting piece, wherein a flow resistance formed by a constricted flow cross section is provided in the dip tube. The application furthermore relates to a fluid tank assembly.

A fully-integrated, flow-control module for top-fill fuel tanks operates with a fuel line attached that supplies fuel under pulsating pressure. There are two bleed paths in the module, which open and close sequentially in response to the position of a fuel float within the module. In order for a main valve plunger, which controls fuel entry into the tank, to fully close, both bleed paths must be closed. A first bleed path closes first, followed by closure of the second. For the main valve plunger to fully open, both bleed paths must be open. The second bleed path opens first. Movement of the main valve plunger is controlled by both a biasing spring and pressure beneath the plunger. Pressure beneath the plunger builds up to a level sufficient for the biasing spring to fully close the plunger against a valve seat when both bleed paths are closed.

A filling device includes a filling pipe to extend into a liquid container for fluidic connection to the liquid container, a filling head operatively connected to the filling pipe, a venting pipe to vent the liquid container, the venting pipe having an open venting pipe section at an end thereof, and an indicator member configured to visually indicate a filling condition of the liquid container. During a filling sequence of the liquid container in a condition in which the liquid container is not full of liquid, the indicator member is to be impinged upon by outflowing air in the venting pipe at a force such that the indicator member assumes a first recognizable condition. During a filling sequence of the liquid container in a condition in which the liquid container is full of liquid, the indicator member is not impinged on by outflowing air in the venting pipe at a force such that the indicator member assumes a second recognizable condition.

A fuel tank vent shutoff valve is provided with a leak countermeasure for preventing liquid fuel leaking from the vent shutoff valve into an evaporative emissions canister. In one embodiment, the vent shutoff valve includes a case disposed over a valve body. The case includes a floor surface surrounding an opening and a cover disposed over the case. The case also includes a flange structure extending away from the floor surface towards an inside surface of the cover. The inside surface includes an annular wall aligned over the opening and extending towards the floor surface of the case. The annular wall includes a first section having a first height that is greater than a second height of a second section. A free end of the first section extends past a free end of the flange structure of the case to prevent fuel from leaking into the evaporative emissions canister.
