TANK VENTING CONTROL ASSEMBLY. |
摘要 |
<p>An apparatus is provided for controlling venting of fuel vapor through an aperture in a fuel tank. The apparatus comprises a housing mounted in the aperture and a valve moveable in the housing between a blocking position blocking flow of fuel vapor from the fuel tank through the housing and a venting position allowing flow of fuel vapor from the fuel tank through the housing. A spring biases the valve towards its blocking position. A mechanism is provided for using fuel vapor from the fuel tank to move the valve against the spring towards its venting position. The using mechanism includes a venting control chamber receiving fuel vapor from the fuel tank in a conduit communicating fuel vapor from the fuel tank to the venting control chamber. The conduit includes a first portion and a second portion moveable relative to the first portion to define an intermediate portion. The apparatus further includes a flexible partition extending between the valve and the first portion to provide a barrier to prevent fuel vapor venting through the housing from entering the intermediate portion.</p> |
