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.

Fuel-vapor valve system and components therefor

A fuel tank isolation valve (FTIV) is provided, configured for being disposed in fluid flow communication with a fuel tank and a carbon canister of a fuel system, the FTIV including an integrated controller and a solenoid coupled to a valve, the solenoid being movable between a normally closed position in which the valve is closed and prevents fluid communication through a first flowpath through the FTIV, and an open position in which the valve is open and allows for fluid communication through the first flowpath, the integrated controller being configured for generating actuation signals to the solenoid, responsive to parameter signals received from one or more sensors associated with the fuel tank. A sensing system for use with a fuel system is also provided, the sensing system including the FTIV and at least one such sensor. A fuel system is also provided, including a fuel tank and a carbon canister, and also including the sensing system for use therewith.

Solenoid assembly for a valve

A pressure relief valve () is provided having a first tubing () connectable to a fuel tank () and a second tubing () connectable to a fuel vapor treating device (), the pressure relief valve comprising: an externally actuated (hereinafter EA) valve () disposed between the first tubing () and the second tubing () and being configured for pulsed actuation by a controller () thereby allowing pulsed fluid flow through a primary port () disposed between the first tubing () and the second tubing ().

Pressure relief valve

Provided is a fuel accessory for a vehicle's fuel system, the fuel accessory including a housing configured with a confined space, at least one fluid inlet port extending into the confined space, at least one fluid outlet port extending from the confined space, and at least one liquid drain port extending from the confined space. An inlet flow path defined by the inlet port extends tangentially relative to a wall portion in the confined space.

Vehicle fuel accessory

A draining device for draining fuel from a fuel vapor system into a fuel tank is provided, the draining device comprising a port configured to be coupled to a fuel vapor accessory and a sealing member displaceable between a closed position in which the port is closed by the sealing member and an open position in which fuel from the fuel vapor accessory can be drained into the tank, wherein the sealing member is displaced into the open position when pressure in the tank is substantially equal to the atmospheric pressure and the fuel level in the tank is below the fuel level in the fuel vapor accessory.

Draining device

Provided is a fuel valve including a uniform valve housing accommodating a roll-over valve (ROV), an over-pressure relief valve (OPR) and a pressure retention valve (PRV), wherein a pressure retention disc is substantially axially displaceable within a top chamber of the valve housing, between a normally closed portion in which it sealingly bears over an outlet port of the flow path and an open position; the pressure retention disc is configured with a cutout portion at least partially enveloping a pressure relief port of the valve.

Fuel valve

A valve for a fuel tank is provided, comprising a housing configured with a float chamber and a disk chamber being in flow communication through an intermediate flow path. The disk chamber is configured with a fluid outlet port from the intermediate flow path and a valve outlet and a fluid inlet port is sealable by a sealing member of a float member axially displaceable within the float chamber to selectively facilitate fluid flow to or from the float chamber via the valve. The fluid outlet port is sealable by a pressure holding member axially having an under pressure bleed valve displaceable between a sealed position wherein the under pressure bleed valve is sealed, and an open position wherein the under pressure bleed valve is open, providing passage of fluid therethrough.

Roll over valve

Provided is a roll-over fuel valve configured with a float-sealable fluid path module including a float member axially displaceable within a float housing, between an open position and a closed position. The float member is normally biased in direction of the closed position and the float member includes an open liquid chamber for collecting liquid, thus taking part in the force equilibrium acting on the float member.

A fuel vapor control valve comprising a housing. The housing comprising inlet and outlet ports in flow communication via first and second valve controlled passages. The first valve controlled passage being configured to admit fuel vapor flow in a direction from the inlet port to the outlet port only when pressure at the inlet port exceeds a predetermined threshold. The second valve controlled passage being configured to admit vapor flow in a direction from the outlet port to the inlet port only when pressure at the inlet port drops below pressure at the outlet port. The fuel vapor control valve further comprising a sealing arrangement disposed at an external portion of the housing between the inlet and outlet ports.

Vehicle fuel system and components thereof

Disclosed is a valve having a housing formed with a downstream port and an upstream port, with an axially displaceable plunger biased into sealing engagement of a major flow path extending between the downstream port and the upstream port for admitting flow only in the upstream direction, with the plunger formed having a normally closed minor flow path for admitting flow only in a downstream direction.

Double check valve for a fuel system

A liquid vapor separator for a vehicle's fuel system, said liquid vapor separator comprising a body having an inlet connectable with a venting system of a fuel tank and a vapor outlet connectable to a fuel vapor treating device, and a condensation space for condensation of fuel droplets, said space being in flow communication with said inlet and with said outlet, and said condensation space extending at or being in flow communication with a filler neck of the fuel system.

Liquid vapor separator
