A float valve () is provided for use with a liquid medium, the float valve having an upright configuration and an inverted configuration. The float valve includes: a housing (), defining at least one inlet port () and at least one outlet port (); a float assembly () movable within the housing; and an auxiliary float member () movable within said housing. The float assembly () comprises a primary float member ('), different from the auxiliary float member, and a spring element (). The primary in float member is configured for closing the at least one outlet port when in abutment therewith, the spring element being configured for providing a biasing spring force to the primary float member in a direction towards said at least one outlet port. The auxiliary float member is configured for providing a net upthrust force with respect to the liquid medium under submerged conditions irrespective of whether the float valve is in said upright configuration or in said inverted configuration.

Float valve

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.
