Abstract

A module (49, 149, 249) for use in a vehicle fuel system, said module comprising a housing (7) having a first port (9), a second port (41) and a passage (57) between the first port and the second port; a closure body (11) that is moveably arranged in said housing; wherein said closure body is configured for closing the passage between the first port and the second port in a first position of the closure body and for allowing access to the passage in a second position of the closure body; and a pump (13) that is integrated in said housing (7), wherein said pump (13) communicates with the firstport (9) and is configured for pumping fluid into or out of the first port (9) while the closure body (11) is in the first position, characterized in that the module (49, 149) further comprises a motor (15) and a closure body actuator (67) configured for positioning the closure body (11, 111) in at least the first position and the second position, wherein said closure body actuator is driven by said motor (15), and said motor is configured for driving the pump (13) while the closure body is in the first position.

Description

technical field [0001] The present invention relates to the field of vehicle fuel systems with vapor control, and modules for use in such systems. More generally, the invention relates to the field of conventional vehicles and hybrid vehicles. Background technique [0002] A vehicle fuel system may be used to store fuel and provide fuel to an engine. For example, a motor vehicle that includes an internal combustion engine may be provided with a vehicle fuel system that includes a vehicle fuel tank that stores liquid fuel (eg, gasoline, diesel, methanol, ethanol) and / or other fuels. Liquid fuel in the vehicle's fuel tank may evaporate into volatile fuel vapors in the vehicle's fuel tank. Vehicle fuel systems are generally provided with vapor outlets for venting fuel vapors from the fuel system. Emission of fuel vapors into the atmosphere forms part of vehicle emissions. To control emissions of volatile fuel vapors, vehicle fuel systems are typically provided with evaporat...
