Valve unit for a motor vehicle fuel supply system

摘要

A valve unit for the fuel-supply system of a vehicle includes a body (3) adapted to be connected rigidly to an element of the supply system, particularly a tank or fuel filler pipe, in a position which is normally higher than the level of the fuel. The body (3) includes a valve housing (5) and a cover (7) for the housing (5) having means (11) for connection to a service duct of the vehicle. The cover (7) is made separately from the housing (5) and releasable retaining means (5a, 7c) are provided for attaching the housing (5) to the cover (7). The cover (7) is formed from a material which can be welded directly around an aperture in the element of the supply system. <IMAGE>
